440 cylinder head bolt torque.

Post by molteniman » Mon Apr 15, 2013 10:18 am

Good afternoon. Before I torque the cylinder heads bolts on a B18U engine, I want to get the sequence right. The Haynes manual says 22 lbft, then 52, wait 3 minutes and slacken, then 15 lbft and finally angle-tighten 123 degrees +/- 2. However, the instructions with the head gasket (British Gaskets Group) say 22 lbft, the 50 degrees, then -180 degrees, then 18 lbft and finally 213 degrees. Which is correct, or do both arrive at the same tightness? Any help would be gratefully appreciated.

Welcome to Matthew's Volvo Site.

The attached corresponds with the Haynes manual and is from a reputable trade book.

Before starting lightly oil the screw threads and the bolt head mating surfaces then put them in finger tight.

I wouldn't think that the gasket instructions are correct as the final 213 degrees is a lot more than 123 degrees and would result in the head being too tight.

Many thanks for lightening response. Weather permitting, I'll finish the job tomorrow. Fingers crossed.
