Re: 36K Cam Belt change for the GT JTDm
Checking the cambelt at 36k service appears to be part of that service.
When my 2004 GT JTD was serviced at 36,000 miles last March at Fish Bros at Swindon they tried to inspect the cambelt as part of that service but then phoned to say that they could not remove an inspection cover since the screw was cross-threaded into the block. They said they needed to remove the engine to drill it out but it would be covered by the 3rd year warranty.
They ended up replacing the cambelt and tensioner, but also the waterpump as it showed signs of leaking - fortunately all done under warranty.
Incidentally, VW seem to be as cautious as Alfa about cambelts now, at least on petrol engines. The local dealer says that the cambelt must be replaced on my wife's 2003 Polo Twist 1.4 petrol which has only covered less than 35,000 miles, because it is now 4 years old!
The handbook had stated that it should not need replacing until 120,000. The dealer says that it is a generic page which does not apply to this model and that, anyway, VW have now changed the service requirement.
