just about to put the head back on my diesel, can anyone tell me the torque specs? I've got a bentley manual but it only cover petrol models.

thanks

Hi,

I've got a Haynes diesel Golf manual and it says stage 1 is 7.5 kgfm, and then stage 2 is another 1/4 turn to each bolt. It also says DON'T retorque after 1600km. This is for the 1.5 litre motor.

The Bentley says 90Nm and 66ft.lbs. Procedure:
"Torque head bolts to 50Nm (37ft.lb). Go over the sequence a second time, torquing the bolts to 70Nm (52ft.lbs), and then a third time torquing the bolts to 90Nm (66ft.lbs)"
Straight from 'The Bible'. The 1.5 doesn't have "stretch" bolts so the procedure is simple. The Bentley makes no mention of re-torquing after a given milage or period.

thank guys,

can't wait to get it on the road, I drive 50k's to work, my Syncro is a little heavy on the juice and I don't like racking up too many k's on it and my other car is a '79 bmw 323i 5speed and it is only a matter of time before I get busted speeding in it. :twisted:

Interesting that two different manuals give different proceedures! Converting kgfm to Nm means multiplying by 9.81, so in Nm the Haynes stage 1 is 74Nm, then an additional 1/4 turn, so the end result is about the same as the Bentley manual.

I had the head off in my 1980 1.5 GLD back in 1991, and these are the numbers I used. The head gasket hasn't leaked in 14 years, so I guess this torque has been OK!

I've also had a 1985 GTD turbo diesel with the stretch bolts, with these the tensioning is much less forgiving that the non-stretch type. When I replaced the head on this car a couple of the old bolts snapped while removing them. They snapped just below the surface of the head - what a pain!

By the way, what have you had to do to your car?

The Audi 100 diesel that I had (RIP....What a shame!) needed stretch bolts. It was an '81 model privately imported from NZ. I got the new bolts from Canada, and the head gasket too. Had to buy a 12pt in-head socket to do the job. Just as an aside, it really pi**es me off that we don't get fine cars like that in Oz.
