When should you change the cam belt on the Peugeot 1.2 PureTech petrol engine? Confusion around cam belt changes are common but the answer for the 1.2 petrol engine in the 2008 is anything but straightforward.

The cam belt - or timing belt to use its correct term - plays a vital role in the operation of your car because it controls the timing of the engine and prevents the pistons and valves in the cylinders from smashing into one another. 

Not all engines use cam belts - some use chains which are lubricated by the engine oil and are designed to last the life of the car. Obviously, avoiding costly belt changes is something that's seen as a big bonus for car buyers. That's why some manufacturers, like Peugeot, have started to use a 'wet belt' system for their petrol engines which protects the belt by lubricating it with oil and allowing it to last much longer than a conventional system.

As a general rule, I recommend a cam belt change every 60,000 miles or five year (whichever comes first). This is because most failures we hear about occur when the cam belt is past these milestones. And take it from us, the impact of a cam belt failure on an engine is usually terminal. 


The 1.2 PureTech is one of these wet belt engines. However, while some of Peugeot's wet belt rivals promise up to 10 years or 150,000 miles of trouble-free motoring on the same cam belt, the 2008 and its 1.2 PureTech will only go up to 60,000 miles and/or six years before it needs to be replaced. 

What's more, because the 1.2 PureTech engine uses a special belt in the oil system, the cost to replace it is higher, with dealers quoting a minimum of £500. In comparison, a standard cam belt in a small car will set you back £300 at a local garage or around £400 at a dealer. 

Now I don't know why the 2008's wet belt system requires a change every 60,000 miles or six years (whichever comes first). But I do know from the feedback we have received via ASK that some Peugeot owners have suffered problems with the timing belts in the older versions of the 1.2 PureTech engine. Perhaps these issues have prompted Peugeot to err on the side of caution. 

But to answer the original question, when should you change the cam belt on the Peugeot 1.2 PureTech petrol engine? Every 60,000 miles or six years (whichever comes first). Just don't expect it to be a cheap job.
