A new cambelt means peace of mind
Cambelt replacement
Cambelts or timing belts need changing at regular intervals depending on the manufacturer; however, due to the fact that leisure vehicles typically cover low mileages, we recommend replacing your cambelt based on time rather than distance. For example, Fiat recommends cambelt replacement every 5 years, while based on our experience we recommend that the Ford wet cambelts are replaced every 3 years.
Some engines are manufactured with a timing chain that is essentially maintenance-free.

Cambelts Explained
How often should I change the cambelt on my vehicle?
A cambelt controls the timing of your engine's internal components.
How often should I change the cambelt on my vehicle?
A cambelt controls the timing of your engine's internal components.The cambelt (or timing belt) is a crucial part of your motorhome’s engine. It synchronises the crankshaft and camshaft, making sure the engine’s valves open and close at the right time during each cylinder’s intake and exhaust strokes. If this timing is off, the engine won’t run properly.
In many engines, the cambelt also drives the water pump and other vital components. As it is made of reinforced rubber, it wears over time and needs regular replacements to avoid engine damage.
How often should I change the cambelt on my vehicle?
Typically every 3 - 5 years (Depending on manufacture). We recommend 3 - 5 years, as motorhomes and campervans rarely cover the distance, to trigger a mileage-driven renewal.

Typically every 3 - 5 years (Depending on manufacture). We recommend 3 - 5 years, as motorhomes and campervans rarely cover the distance, to trigger a mileage-driven renewal.The recommended interval varies by engine manufacturer but for most motorhomes (especially those with Fiat Ducato, Peugeot Boxer bases), the cambelt should be replaced every 5 years or 60,000–80,000 miles. Check your owner’s manual for the specific schedule. For the “wet belt” fitted to the 2.0L Ford Transit range, we recommend a 3 year interval between new cambelts.
If you haven’t driven far, the rubber will still degrade over time. So, if your motorhome is mostly in storage or used seasonally, the time-based interval is really important. Leaving a cambelt too long increases the risk of failure, which can cause engine damage.

What happens if my cambelt breaks?
Your engine could suffer severe damage, which can require a full rebuild or replacement.

Your engine could suffer severe damage, which can require a full rebuild or replacement.If a cambelt fails, it can cause serious engine damage that’s costly to repair. In some cases, replacement may be the more practical option, which is why keeping on top of your cambelt schedule is such a smart way to protect your motorhome and avoid unexpected expenses.
Can I tell if my cambelt is about to fail?
In most cases you usually cannot and cambelts often fail without warning.
Can I tell if my cambelt is about to fail?
In most cases you usually cannot and cambelts often fail without warning.Cambelts rarely give clear signs before they fail. Unlike a squeaky fan belt, a timing belt may appear fine even when it’s nearing the end of its life. Cracks, fraying, or worn teeth might be visible during inspection but many failures happen internally or suddenly.
That’s why preventative replacement based on time or mileage is the safest route. Mechanics may spot early signs during a service, but there’s no reliable way to visually predict failure without removing the belt, which is a labour-intensive job.

Can I drive my motorhome if the cambelt is overdue for replacement?
We do not recommend as it's a major risk, you could seriously damage your engine.
Can I drive my motorhome if the cambelt is overdue for replacement?
We do not recommend as it's a major risk, you could seriously damage your engine.Driving with an overdue cambelt is a gamble. While the vehicle may still run normally, every mile you drive increases the risk of the belt snapping without warning. If that happens, especially in an interference engine, the damage can be severe. Potentially causing bent valves, piston damage, or a completely ruined engine.
It’s easy to put off because the vehicle “feels fine” but a cambelt doesn’t show visible wear like tyres or brakes. If you’re even slightly overdue, it’s strongly recommended to get it changed before your next long trip or tour. It’s a classic case of prevention being far cheaper (and less stressful) than the cure.

Does my motorhome have a cambelt or a timing chain?
It depends on the engine, some use belts and others use chains.
Does my motorhome have a cambelt or a timing chain?
It depends on the engine, some use belts and others use chains.Most motorhomes based on Fiat Ducato, Peugeot Boxer, or similar platforms use diesel engines with cambelts. Some Ford Transit-based models use timing chains, however the 2.0L “wet belt” Ford engine uses a timing belt.
Timing chains typically last longer and don’t have a strict replacement schedule but they’re not maintenance-free and can stretch or fail in high-mileage engines.
If you’re unsure, check your owner’s manual or ask your service provider. Knowing what your engine uses is essential for planning maintenance and avoiding unexpected breakdowns.
