Cambelt change 4.2

[Ianmanchester]

Hi looking at changing the cambelt on my 4.2 'ars' engine. Apart from eurocarparts can anyone recommend a parts specialist. Euro car parts want the best end of 450 for the kit.

try these, as you are prob aware you should change rollers and tensioner and prob water pump aswell, this link does a kit with belt and tensioner and also belt and pump but no rollers, but its up to you if you want to put OEM parts on your engine or dealer parts or a mix as the dealer will sell you rollers etc.

Thanks George,
Does anyone know the differences in 4.2 engines? ie, mine is a ARS, but there are various other codes, this is all in the quest to find a cambelt kit, I have seen othere kits for AWN engines (mostly american websites), but will a kit like this fit.
