Hi I read up on here and understood an 07 Cooper diesel is a cambelt. So my car had fsh by Mini Oxford by previous owner but now has 160,000 on clock. I asked service desk to confirm its a belt not chain, he said chain, I said not according to this site, so he went away and came back confirming it is a belt. He said they have never changed one ever and no life or mileage is given to changing it and no damage is caused if it snaps apart from it leaving you stranded, so can anyone confirm he is correct about the no damage if it snaps point, and also don't always trust the answer from a main dealer because the first response was incorrect, any help appreciated, thankyou.
Look at these pics: RealOEM.com Diagram Selection
It looks like a toothed belt from crank to cam, but there's also a chain with a tensioner between the two camshafts.
With a compression ratio of 16.5:1, I seriously doubt that the R56 Cooper D is a non-interference engine.
I would expect valves would get bent with a snapped belt.
Hi Cristo, that diagram is interesting, that belt is like the v belt on Mercedes, and that's the word I was looking for, non-interference. Well my mileage is miles not kilos so maybe worth changing, it seems they have a belt and chain, chain for camshafts and belt for timing and alternator etc I presume?, thanks for the reply.
i had my cambelt changed in april sounded like a load of birds tweeting under the bonnet, had a replacememnt water pump changed at same time as they are all connected to the belt, cost £495, runs like a dream !!!
Thanks for posting Andy. A couple of years ago I rang my local mini dealears and asked when the cambelt should be changed as it was not mentioned in the services, the person said all mini/BMW cars after 2007 are cam chain.
My Mini Cooper D is 57 reg with the PSA engine and does have a cam belt. Ive just had it changed (not by the dealers)
The engine has done 99,800 miles and the belt had signs of wear but was ok. The water pump had a very slight leak, ie stain down from the shaft seal.
The cam belt kit is £116 and includes a new water pump. Total cost including fan belt and antifreeze £285.
My advice to anybody needing work done, either do it yourself or go to a trusted local garage with a good reputation.
