shallishanti? Posted February 15, 2007 Posted February 15, 2007 What are the cambelt change intervals for the various HDi engines? Particularly interested in the Mk1 2.0. Quote
proinnsias Posted February 15, 2007 Posted February 15, 2007 I can't comment on the HDi change interval - my manual's a few miles away !! but http://www.honestjohn.co.uk/forum/post/index.htm?t=7920 has an interesting formula : Take a belt base life of 60,000 miles. Now apply the following factors as multipliers: Crank pulley teeth (half cam pulley number) 19t 0.7; 20t 0.9; 21t 1.0; 22t 1.05. Next, apply the following factors as multipliers: Fixed tensioner 1.0; Undamped sprung tensioner 0.8; 3/4 wide belt 0.75;1 wide belt 1.0; Diesel engine 0.85. As an example, the old Ford CVH 1.4 engine had 19 teeth on its crank pulley (0.7), a fixed tensioner (1.0), and a 3/4 wide belt (0.75). Change interval becomes 60,000 x 0.7 x 1 x 0.75 = 31,500 miles.

shallishanti? Posted February 15, 2007 Author Posted February 15, 2007 Thanks (I think!). Sounds a bit complex and far fetched to me. Begs the question - how many teeth are on the pulley? I'm trying to weigh up service costs wrt to buying cars at certain mileages. Quote

I'm trying to weigh up service costs wrt to buying cars at certain mileages. had mine done @ 100k, told 60-70k safest option, but worst option is after belt breaks. if in doubt, change it Quote
proinnsias Posted February 15, 2007 Posted February 15, 2007 had mine done @ 100k, told 60-70k safest option, but worst option is after belt breaks. if in doubt, change it I just had a look in the service handbook from my C5 - HDi engines are at 100k miles for normal wear, or 80k for severe ... Hope that gives you good news <_< Quote
shallishanti? Posted February 15, 2007 Author Posted February 15, 2007 100k miles - wow that IS good news!!! Many thanks - helps me no end. Quote
shallishanti? Posted February 24, 2007 Author Posted February 24, 2007 Well I've taken the plunge and have purchased a 52 plate 2.0Hdi SX Estate. Pick it up on tuesday. It drives very nicely, full service history etc. Hopefully won't have to come back for too much advice! Quote
