Cambelt or Chain? How to Check Which One Your Car Has
Three possibilities: dry cambelt, timing chain, or a wet belt in oil. Each has a very different service cost. Here is how to find out for free.
Whether your engine has a cambelt, a timing chain, or a wet belt makes a huge difference to running cost. Chains are usually sealed inside the engine and last the life of the car. Dry cambelts need replacing every few years. Wet belts have their own short interval and a habit of taking the oil pump with them when they fail.
The fastest way to find out
Send us your registration and the year on WhatsApp. We will check it against the manufacturer schedule and tell you in two minutes. Free, no obligation, no sales pitch attached.
If you want to check yourself
- Find your exact engine code. It is on the V5 logbook in section D2, or stamped on the engine block, or shown on the bonnet sticker.
- Search the engine code plus the phrase 'timing belt or chain'. Owner forums and manufacturer workshop schedules will tell you straight.
- Open the bonnet. A dry cambelt usually lives behind a black plastic cover on one end of the engine. A chain is inside the engine and there will be no cover. A wet belt is also hidden inside, with no cover visible.
Common examples we see every week
- Ford Fiesta 1.0 EcoBoost: wet belt in oil. Plan for replacement at 6 years or 100,000 miles.
- Peugeot 208 1.2 PureTech: wet belt. Same conservative interval.
- VW Golf 1.4 TSI EA211: dry cambelt. Replace every 5 years.
- BMW B58 3.0 (newer 3 Series and Z4): chain, no scheduled replacement.
- Audi 2.0 TFSI EA888 (Gen 3 onwards): chain, no scheduled replacement.
- Toyota Yaris 1.5 hybrid: chain.
- Mini 1.6 N14 petrol: chain, but a known tensioner failure point worth checking on older cars.
What happens if you ignore the schedule
A snapped cambelt or wet belt on an interference engine, which is most modern engines, lets the valves and pistons meet at the wrong moment. Bent valves, cracked pistons, sometimes a holed block. We have rebuilt engines that would have cost a tenth of the rebuild if the belt had been changed on time.
If you genuinely do not know what is in your engine, ask before the next service. Two-minute WhatsApp answer, no charge.
