Is Your Engine Bay Getting a Shower?

Attention Fiat, Peugeot Motorhome Based Vehicles

Is Your Engine Bay Getting a Shower? The Hidden Water Leak in the Engine Compartment that could lead to big repair bills!

If you’re driving a Fiat Ducato, Peugeot Boxer, or similar van-based motorhome, you might be driving with a "hidden" risk that could lead to significant repair bills down the road. It’s a common issue that many owners don't realize exists until it’s too late: the scuttle panel water leak.

For those of us in the community who spend time in our vans, keeping them in top condition is a priority. Unfortunately, one of the most persistent issues across these popular chassis models (especially those from 2014 onwards) is water ingress into the engine bay.

The Problem: Why It Matters

The plastic panel sitting between your windscreen and your engine bay—known as the scuttle panel—is designed to channel rainwater away from your engine. However, over time, the seal between this panel and the windscreen can deteriorate or buckle.

When this happens, the panel fails to do its job. Instead of water draining safely away, it flows directly into the engine compartment. This isn't just a minor annoyance; it can lead to:

• Corroded Injectors: Constant exposure to moisture causes rust, which can lead to difficult startups and expensive repairs.

• Wiper Linkage Failure: Water collecting near the mechanism can cause the linkage to rust prematurely.

• Electrical Damage: Water dripping onto engine electronics or connectors can cause failure, which is notoriously difficult to diagnose and fix.

The Fix: How to Stop the Drip

The good news is that this is a manageable DIY job if you’re handy, and the results will give you peace of mind during the next storm.

I’ve put together a guide with a video that walks you through the entire process. In the video, we cover:

• Identifying the failure points: Seeing exactly where the water enters [00:26].

• Disassembly: How to safely remove the wiper arms and the scuttle tray [02:28].

• Deep Cleaning: Why removing years of dirt and degreasing the surfaces is critical before sealing [04:57].

• Sealing: Replacing poor-quality original seals with a robust, long-term solution [07:38].

• Maintenance: Ensuring your drainage hoses are clean and secure [01:47].

A Few Pro-Tips for Motorhome Owners:

1. Regular Checks: Don’t wait for a breakdown. Periodically check your drainage hoses for debris. A simple cable tie can sometimes be used to keep drain holes clear [01:55].

2. Don’t Ignore the "Normal" Excuse: If a garage tells you water in the engine bay is "normal," take it with a grain of salt. While some mist is inevitable, constant pooling water is not and will cause long-term harm.

3. Prevention is Key: If your scuttle panel looks like it’s pulling away from the glass, address it immediately. A proactive repair is always cheaper than replacing rusted injectors or damaged electronics.

Whether you're a seasoned mechanic or a DIY beginner, taking an hour or two to seal this area is one of the most effective ways to protect your motorhome investment.

16 Easy Jobs to Get Your Motorhome Ready

 

16 Easy Jobs to Get Your Motorhome Ready for Trouble-Free Touring

As the touring season approaches, spending a little time on motorhome maintenance can save a lot of frustration once you're out on the road. Whether your motorhome has spent the winter in storage or you've continued touring throughout the colder months, carrying out a few simple checks now can help ensure a safe and trouble-free adventure.

Assuming your annual habitation service and MOT are up to date, here are 16 straightforward jobs every motorhome owner should consider before setting off on their next trip.

1. Check Your Vehicle Battery

A healthy starter battery is essential. Inspect it for any signs of damage, swelling or corrosion and check that it is holding a full charge. If necessary, recharge the battery according to the manufacturer's guidelines.

2. Inspect Your Leisure Battery

Your leisure battery powers many of your onboard systems when you're off-grid. Make sure it is fully charged and capable of holding that charge. Older batteries may benefit from a conditioning charge using a dedicated battery charger.

3. Clean Corroded Battery Terminals

White powdery deposits on battery terminals indicate corrosion. Carefully clean these away and protect the terminals with a light coating of petroleum jelly to help prevent future oxidation.

4. Check Tyre Pressures

Tyres are one of the most important safety items on any motorhome. Verify that all tyre pressures match the manufacturer's recommendations, including the spare wheel if you carry one.

5. Inspect Tyre Condition

Look closely for cracks, cuts, bulges, uneven wear or other signs of damage. Motorhome tyres often age before they wear out, so condition is just as important as tread depth.

6. Give the Tyres a Thorough Clean

Cleaning tyres isn't just about appearance. Washing away dirt and grime makes it easier to spot any defects that could otherwise go unnoticed.

7. Test the Brakes

After a period of storage, brake discs can develop surface rust. Take the motorhome for a short drive and check that braking performance feels normal and consistent.

8. Check the Handbrake

A handbrake can become sticky when a motorhome has been parked for extended periods. Ensure it applies and releases smoothly without hesitation.

9. Inspect Brake Discs

Following a short drive, inspect the brake discs. They should appear clean and shiny. Any excessive rust, scoring or poor braking performance should be investigated by a qualified technician.

10. Check All Exterior Lights

Confirm that headlights, sidelights, brake lights, indicators, reversing lights and fog lights are all working correctly. Don't forget to ask someone to help if needed.

11. Test Interior Lighting

Check every interior light fitting, replacing failed bulbs where necessary and ensuring all connections remain secure.

12. Test Habitation Appliances

Run each appliance, including the fridge, heating, water heater and cooker. Identifying faults at home is far better than discovering them on your first night away.

13. Inspect Windows and Rooflights

Open and close all windows, roof vents and skylights. Check seals for signs of wear and ensure all catches operate correctly. Spay all the seals lightly with silicone lubricant to keep them soft and subtle.

14. Lubricate Door Locks

Locks that sit unused can become stiff and difficult to operate. Applying a suitable dry lubricant helps keep lock mechanisms working smoothly and prevents costly damage.

15. Lubricate Locker Hinges and Latches

External lockers are exposed to the elements and can seize if neglected. A suitable silicone-based lubricant can help keep hinges and catches operating freely.

16. Clean and Sanitise the Water System

Puriclean Water Tank Cleaner

Fresh water tanks and pipework should be thoroughly cleaned before the touring season begins. Use a dedicated tank-cleaning product, flush the entire system and rinse thoroughly with clean water. This not only freshens the water supply but also helps eliminate unwanted odours from the grey-water system.

Essential Supplies for the Job

Most of these maintenance tasks require only basic equipment, including:

• Car shampoo and warm water
• Microfibre cloths

• Silicone lubricant

• Graphite lock lubricant
• White vinegar
• Petroleum jelly
• Old toothbrushes and small brushes
• A tyre pressure gauge
• A multimeter

Keeping these items in your motorhome maintenance kit will make regular checks quicker and easier throughout the year.

A Little Effort Goes a Long Way

None of these jobs require specialist mechanical knowledge, yet together they can significantly improve reliability, safety and comfort on tour. Spending a few hours carrying out these simple checks before the season starts can help prevent breakdowns, avoid costly repairs and give you peace of mind wherever your travels take you.

We hope this checklist helps you get your motorhome prepped and ready for many miles of trouble-free touring.

 Lithium vs. Lead-Acid

 Is a Lithium Leisure Battery Worth the Investment for Your Motorhome or Campervan?

If you have spent any time browsing motorhome forums, social media groups, or accessory shops recently, you will undoubtedly have noticed a massive shift in how we power our leisure vehicles. The traditional lead-acid leisure battery a staple of the touring community for decades is facing serious competition from modern lithium technology.

But as you look at the options available on the market, one glaring question inevitably arises: Are lithium leisure batteries actually worth the money for a motorhome or campervan?

Upgrading your electrical setup is one of the most significant modifications you can make to your vehicle. It is not a decision to be taken lightly, as it directly impacts how you travel, where you can stay, and how much money stays in your wallet. Ultimately, whether lithium is a must-have upgrade or an expensive overkill comes down to two major factors: your initial budget and your personal touring style.

To help you cut through the marketing jargon and make an informed decision, we have put together a highly detailed breakdown of the comprehensive pros and cons of lithium leisure batteries, looked at through the lens of real-world touring.

The Pros: Why Lithium is Revolutionizing Motorhome Power

There is no denying that lithium technology brings a massive leap forward in performance. If you are looking to elevate your touring experience and gain true independence on the road, a lithium setup offers several game-changing advantages.

1. Massive Weight Savings (Boosting Your Payload)

Every motorhome and campervan owner knows the constant struggle of managing vehicle weight. With strict legal payload capacities, every kilogram counts. Traditional lead-acid or AGM batteries are incredibly heavy, often weighing anywhere between 25kg to 35kg each. If you want a multi-battery setup to get more power, you can easily eat up 70kg of your payload just on batteries.

Lithium batteries are significantly lighter often up to 50% to 60% lighter than a lead-acid battery of equivalent physical size. By switching to lithium, you instantly free up valuable payload capacity, giving you more headroom for water, bikes, gear, or just peace of mind when crossing the weighbridge.

2. 100% Usable Capacity (Double the Power)

One of the biggest hidden flaws of standard lead-acid batteries is their "usable" capacity. If you buy a 100Ah lead-acid battery, you cannot actually use 100Ah of power. To avoid permanently damaging the battery chemistry and drastically shortening its lifespan, you should never discharge a lead-acid battery below 50%. This means your 100Ah battery only gives you 50Ah of real-world energy.

Lithium batteries change the game entirely. They allow you to safely access nearly 100% of their stated capacity without causing any harm to the cells. Therefore, a single 100Ah lithium battery delivers the same amount of usable power as a 200Ah lead-acid bank, effectively doubling your available energy in a much smaller footprint.

3. An Incredible Lifespan (A Long-Term Investment)

The upfront price of lithium can cause immediate sticker shock, but looking at the lifespan changes the math completely. A standard lead-acid battery exposed to regular use might last between 300 to 500 charge cycles before its performance degrades significantly—meaning you could be replacing it every few years.

In contrast, a high-quality lithium leisure battery typically lasts over ten times longer, often rated for 3,000 to 5,000 cycles at a high depth of discharge. When you view it as a long-term investment, a lithium battery will outlast multiple sets of lead-acid batteries, usually proving to be the cheaper financial choice over the span of its life.

4. Lightning-Fast, High-Efficiency Charging

Lithium batteries accept charge much faster and more efficiently than lead-acid alternatives, which face increased internal resistance as they fill up. If you have a solar panel setup on your roof, this efficiency is a massive bonus.

On cloudy days, during winter touring, or during unexpected periods of bad weather, a lead-acid battery will struggle to absorb weak solar energy efficiently. A lithium battery, however, will eagerly soak up every single watt your solar panels can generate, maximizing your charging windows and keeping you powered up when conditions are less than ideal.

5. Seamless Handling of Heavy-Drain Inverters

As our vehicles become mobile homes, we are bringing more high-powered household gadgets on the road—think coffee machines, hair dryers, microwaves, and laptops. To run these, you need a motorhome inverter to convert 12V battery power into 230V household electricity.

Drawing massive amounts of current causes a severe voltage drop in lead-acid batteries, often causing the inverter to trip out even if the battery isn't empty. Lithium batteries maintain a steady, high voltage throughout their entire discharge cycle, handling heavy-drain appliances with absolute ease.

The Cons: When is Lithium NOT Worth It?

Despite the incredible technological advantages, lithium isn't a magic bullet that is automatically right for every single traveler. There are valid scenarios where sticking with traditional technology is the smarter, more economical choice.

1. The High Upfront Initial Cost

While prices across the market are steadily falling, the initial purchase price of a lithium battery remains significantly higher than a standard flooded, gel, or AGM lead-acid battery. If you are on a tight budget or only use your motorhome a few times a year, justifying that immediate layout of cash can be difficult.

2. Potential Charging System Upgrades

You cannot always just drop a lithium battery into an older motorhome and call it a day. Lithium batteries have specific charging profiles. To get the most out of them—and to protect your vehicle's alternator—you may need to install a Battery-to-Battery (B2B) charger or upgrade your existing mains charger and solar regulator. This potential extra outlay for installation and components needs to be factored into your overall budget.

3. Overkill for "Campsite-Only" Tourers

Your touring style is the ultimate deciding factor. If your idea of the perfect holiday involves driving straight to an organized campsite, plugging into the 230V Electric Hook-Up (EHU), and staying there until it is time to go home, you do not need lithium.

When plugged into a campsite grid, your onboard appliances run off the site's electricity, and your battery is kept constantly topped up. If your 12V power is only ever used for LED lighting and charging your phone while driving between sites, a healthy, budget-friendly lead-acid battery will meet your requirements perfectly without breaking the bank.

4. The Need for Supporting Infrastructure

If you don't have solar panels installed, don't wild camp, and have no intention of ever upgrading your setup to support off-grid living, you will lose out on the core benefits that make lithium so attractive. Without a way to generate power on the move, the rapid-charging capabilities of lithium won't be fully utilized.

The Verdict: Should You Make the Switch?

At the end of the day, deciding whether a lithium leisure battery is worth the money comes down to a clear look at how you like to travel.

If you are a site-hopper who loves the convenience of organized holiday parks, rarely uses an inverter, and values keeping your initial costs low, saving your money and sticking to a high-quality standard lead-acid battery makes total sense.

However, if you are a freedom-loving tourer who regularly heads off-grid, relies heavily on solar power, values every kilogram of payload, and wants a lightweight, long-lasting power source that will confidently run your favorite household gadgets in the middle of nowhere, lithium is undeniably worth every single penny. It shifts your focus away from battery monitoring and puts it back where it belongs: enjoying the journey.

If you have weighed the options and decided that lithium is the ultimate upgrade for your upcoming adventures, we highly recommend looking into Fogstar Batteries. Renowned within the UK and European motorhome community for their exceptional reliability, robust built-in Bluetooth Battery Management Systems (BMS), and top-tier customer support, they offer some of the best value-for-money lithium lifepo4 cells on the market today.

Healthy Water, Happy Touring

 

Healthy Water, Happy Touring: How to Maintain Your Motorhome’s Fresh and Waste Systems

There is nothing quite like pitching up after a long drive, turning on the tap to make a well-deserved brew, and being greeted by a funky, stagnant smell or mysterious black flecks floating in your water.

It’s an easy area to forget about—especially if you are new to the motorhoming world—until a strange taste or foul odour forces you to notice. Fortunately, keeping your onboard water systems hygienic, fresh, and free-flowing doesn't require a degree in engineering. With a few simple habits and regular maintenance, you can keep your plumbing in tip-top shape.

Here is your ultimate guide to maintaining your motorhome’s fresh and waste water systems.

---

1. Refreshing the Freshwater Tank

Your freshwater tank is the core of your off-grid system, but it requires regular attention. When water sits stagnant, it develops a microscopic, slimy layer known as biofilm, which acts as a breeding ground for bacteria.

To keep your drinking water safe, aim to deep-clean your tank every few months, and never leave water sitting inside it for more than two weeks.

The Cleaning Process

• Ditch the Bleach: Avoid using household bleach or Milton fluid. While they are great disinfectants, they can degrade rubber plumbing seals and leave an unpleasant chemical taste that is incredibly hard to flush out. Instead, opt for dedicated caravan and motorhome products like Puriclean or Solbio.

Solbio Fresh Water Tank Cleaner

• The "Slosh" Trick: Empty your tank entirely, refill it partway with warm water, and add your specialist cleaner. Next, take your motorhome for a quick drive around the block. The movement of the vehicle will slosh the mixture around, scrubbing the interior walls of the tank.

• Flush it Through: Once back, fill the tank completely with fresh water and open all your taps until it runs empty. Refill it one more time, thoroughly flushing the lines, including the shower and the toilet flush.

---

2. Don't Forget the Pipes and Water Filters

Cleaning the tank is only half the battle. Stale water, organic residue, and limescale can easily accumulate inside your narrow pipework. Running your cleaning solution through the taps helps, but the best prevention is to completely drain the entire system between trips, especially if your motorhome will be sitting idle for a while.

If your setup features an inline water filter, make sure to replace it strictly according to the manufacturer's schedule. If left too long, neglected filters become a prime source of foul odours.

---

3. Descaling the Hot-Water Boiler

Many tourers assume that because the boiler heats water, it automatically stays clean. In reality, limescale builds up inside your boiler just like it does in a domestic kettle—particularly if you frequently tour hard-water areas.

Official Truma Guidance: The boiler needs regular sterilisation and descaling. Standard camping cleaning products are ideal, but you can also safely use commercial descaling products, vinegar essence, or citric acid.

How to Descale Safely

1. Mix your approved descaling solution into your freshwater tank.

2. Turn on the hot tap briefly to draw the mixture directly into the boiler.

3. Let it sit for the recommended time to dissolve the scale, then flush the system thoroughly with clean water.

4. Avoid Milton or bleach here at all costs, as they can corrode the internal heating elements and damage crucial seals. An annual descale keeps your system running efficiently and your hot water smelling fresh.

---

4. Taming a Grumpy Grey Waste Tank

If the fresh tank is the heart of your plumbing, the grey waste tank is the stomach—and it can get incredibly smelly. Grease, soap scum, and tiny food particles collect here, creating the perfect recipe for foul odours that waft back up through your plug holes.

Top Tips for a Clean Grey Tank

• The Laundry Liquid Trick: Before heading off on a journey, pour a capful of biological laundry liquid down your drain. The active enzymes will break down grease and organic matter, while the motion of your drive provides a thorough scrubbing action. Simply empty the tank when you arrive at your destination.

Solbio

• The Solbio Alternative: Another fantastic method is to pour roughly 20ml of Solbio fluid down your kitchen and bathroom traps after a trip, along with about 20 litres of water. Let it slosh around on your drive home, then empty it safely at home or a disposal point.

• Block the Bits: Always fit simple mesh strainers to your plug holes to catch food scraps, and periodically flush your drains with warm (never boiling) water to maintain a healthy flow.

---

5. Choosing the Right Hoses and Avoiding Contamination

Believe it or not, your choice of filling hose matters. Never use a standard green garden hose to fill your freshwater tank. Garden hoses are prone to internal algae and mould growth when left rolled up in damp spots, and they can leach harmful chemical plasticisers into your drinking water.

Instead, always carry a dedicated, food-grade freshwater hose. These are specifically designed with smooth internal surfaces to prevent bacteria from clinging, and their opaque construction blocks out sunlight to stop algae growth.

MYPURECORE Blue 12mm 1/2" Cold Water Hose Pipe

The Golden Rules of Water Hygiene

• Total Separation: Keep your freshwater hose completely isolated from your waste hoses, leveling ramps, or anything else that sits on the dirty ground. Cross-contamination is the fastest way to ruin your water supply.

• BYO Hose: If a campsite has a communal hose dangling at the water tap, ignore it. You have no way of knowing where it has been or what has crawled inside it. Use your own hose and carry a small selection of tap connectors so you can hook up effortlessly anywhere in the UK or across Europe.

6. Winterizing: Preventing Frozen and Burst Pipes

Winter touring is brilliant, but frozen plumbing can cause catastrophic, expensive damage. If you are touring in a cold snap, insulate any exposed external pipework, activate your onboard tank heaters if you have them, or invest in aftermarket insulation jackets. Always disconnect your fresh water hose overnight during sub-zero temperatures to prevent it from freezing solid.

When storing your motorhome for the winter, you must completely purge all water from the entire system to prevent frost damage:

• Open All Drains: Open your fresh and grey waste valves, alongside any dedicated boiler drain valves.

• Dry the Pump: Run your taps until the water stops flowing entirely, then immediately turn off the water pump so it doesn't run dry and burn out.

• Position the Taps: Leave all your taps open, pointing exactly halfway between the hot and cold settings. This allows air to circulate and prevents pressure build-up.

• Drop the Shower: Drop your shower head down onto the shower tray so any remaining water in the hose can drain out freely.

• Purge the Lines: For ultimate peace of mind, consider an aftermarket air-pressure drain assistant, which gently blows compressed air through the plumbing to clear out those last stubborn pockets of water.
