When installing a new head on a red 202 what tension should the bolts be ? And do I tension them evenly at different stages ?
Griffo,
102N/M in 3 stages 50, 80 and then your 102N/M
Sequence,
Front of  12  8  4  1  5  9  13
Engine   11  7  3  2  6  10  14
I've just put mine together with a monoTorque Gasket set. This is what they recommended.
The sequence and torque is consistent with other types of Gaskets.
Addo,
I should add that a MonoTorque doesn't need retensioning (supposedly), If using others you'll need to retension. Don't forget to use 'head stud sealer' from GMH on all your head stud threads.
Thanks Addo
That looks to be the ducks guts on what I need , plus the tip on head stud dealer
Cheers,
Oops
That should read "head stud sealer " not ( dealer ) or are we playing cards ?
From memory, and believe me, it's a while ago, but there is only 1 or 2 of the head bolts that go through the water jacket, and these are the only ones that need the GM Sealer.
A very good tip is to put a smear of grease on the underside of the head of the bolt. Virtually eliminates friction, which means that your torque wrench is measuring torque only, and not bolt-to-head friction as well. It's also amazing the difference it makes to the "feel" of the procedure, if that makes any sense.
Cheers,
Chesy.
