A couple of questions before I set to on changing the cambelts, firstly is there more than one type of belt tensioner on this engine? If there are options, how do I know which one to get? (I remember on my 1.6K there were 2 options) Secondly, whats the best way to change the rear belt? When I did it last time the engine was out of the car and we removed one of the pulleys, as there's a lip on one of the pulleys, obviously to stop the belt coming off. Thanks all, I've got the pulley lock for the front end, and doing the job should be ok, having done it twice before, apart from now having to do the job with the engine in.
