All You Need To Know About Wet Timing Belts
A wet timing belt, found in many modern vehicles like Ford Fiesta, Ford Focus, Ford Transit, Peugeot 208, Citroën Berlingo, Toyota Aygo, Toyota Proace and Volkswagen models, operates inside the engine and is lubricated by oil. Wet belts reduce friction, enhance performance, and generally last longer than traditional dry belts.
This crucial component synchronizes engine parts, ensuring smooth function. Regular maintenance and timely replacement of the wet timing belt are essential to avoid engine damage. Learn about wet timing belt replacement intervals and how it impacts cars, vans, and motorhomes with TSI or EcoBoost engines.
Many manufacturers have adopted wet timing belts in modern vehicles, especially in newer engines designed for improved efficiency and reduced emissions. Some common makes and models that have engines with wet belts include:
- Ford: Various models, including the Ford Fiesta, Ford Focus, Ford Transit vans, and Ford Ranger, often feature wet timing belts, especially in 1.0L and 1.5L EcoBoost engines.
- Peugeot: Many Peugeot vehicles, such as the Peugeot 208, Peugeot 308, and Peugeot Boxer vans, also utilize wet timing belts in their newer engine designs.
- Citroën: Similar to Peugeot, Citroën models like the Citroën Berlingo and Citroën C3 often have wet timing belts fitted.
- Volkswagen Group: Vehicles from Volkswagen, Audi, SEAT, and Škoda may also feature wet timing belts, particularly in smaller TSI and TDI engines.
- Ford: Various models, including the Ford Fiesta, Ford Focus, Ford Transit vans, and Ford Ranger, often feature wet timing belts, especially in 1.0L and 1.5L EcoBoost engines.
- Peugeot: Many Peugeot vehicles, such as the Peugeot 208, Peugeot 308, and Peugeot Boxer vans, also utilize wet timing belts in their newer engine designs.
- Citroën: Similar to Peugeot, Citroën models like the Citroën Berlingo and Citroën C3 often have wet timing belts fitted.
- Volkswagen Group: Vehicles from Volkswagen, Audi, SEAT, and Škoda may also feature wet timing belts, particularly in smaller TSI and TDI engines.
Although wet timing belts tend to last longer than traditional belts, they still need regular inspection and replacement. Manufacturers generally recommend replacing the wet timing belt between 60,000 and 150,000 miles or at specific time intervals. Neglecting this maintenance can result in costly repairs if the belt fails.
In conclusion, while wet timing belts offer advantages like extended life and smoother performance, they are still a crucial part of the engine that requires attention. If your car, van, or motorhome has a wet timing belt, consult your manufacturer’s maintenance schedule to ensure your engine stays in top condition.

The customer service was 1st class.
John & Sharon King - Dethleff A Class Motorhome
I was pleasantly surprised to be given a bill much less than anticipated
John Barnes - Thurton resident
I can easily see why they get 5 stars
⭐⭐⭐⭐⭐
I had my Ford Focus ecoboost cambelt and water pump changed today. I chose this garage because of the reviews and I can easily see why they get 5 stars. Fantastic service from start to finish. The ecoboost has a wet internal belt so it does need extra care, but when Ford wanted £2000 to carry the work out I looked else where. And that’s why I chose Thurton Auto Centre, and I would recommend you do the same. I cannot fault anything. All the parts used were genuine Ford and carried out to a high standard. The mechanic even showed me my old belt saying it was the right thing to do as it was on its way out! Thanks again.

You don’t get that level of professionalism just anywhere
⭐⭐⭐⭐⭐Motorhome Buying Experience at Thurton Auto CentreMy wife and I bought a Detheffs Motor Home …. Right from the moment we arrived to just view the vehicle we were greeted by Kevin who was not overbearing like most high pressure salesman.. quite the opposite.!!! He explained all the features and left us to take our time to look inside and out and then after a while return to see if we had any questions.?? Which we had a few as we have never owned a Motor Home before…. We shook hands and left with absolutely no pressure to push us into a sale.… after we returned the next day we once again had to good guided tour of the home and we then decided to go ahead and purchase the Vehicle …. They then said the vehicle will go into the valeting shop for a thorough clean inside and out not that it needed it ?? But my God what an amazing job they’ve done.Terry then came over to see us and between Kevin & Terry the whole process of buying with total confidence couldn’t have gone smoother.!!! Absolutely nothing was to much trouble .. you don’t get that level of professionalism just anywhere … For all our servicing and retro fits we will not be going anywhere else .. Thurton Auto Centre scores 10/10 For us ….Terry & Nicola Local residents

I can't recommend this garage enough. I broke down on way to Bedfordshire and they sorted my car out straight away. Absolutely brilliant

Five stars isnt enough i would give 10 if i could
⭐⭐⭐⭐⭐
Drove down for the weekend from london and had something go wrong with my car. They managed to fit me in at really short notice and they didnt try to rip me off. I was able to drive back to london safely and without having to be inconvenienced by being stuck there until i found a way of fixing my car or getting it back. Five stars isnt enough i would give 10 if i could

would recommend Thurton Auto Centre to anyone who are feeling let down by their own garage. They are an independently owned garage who genuinly wants to look after its customers hoping they will return, I certainly will.
Huge Thank You...
