Tighten the cylinder head bolts as follows:

 

 

 

1. Step 1: Torque all the bolts in sequence to 22 ft. lbs. (29 Nm).
2. Step 2: Torque all the bolts in sequence to 51 ft. lbs. (69 Nm).
3. Step 3: Loosen all bolts in sequence by 180 degrees, then loosen an additional 180 degrees.
4. Step 4: Tighten all bolts in sequence: 40-45 degrees.

 

This is the information I found online for my 1999 SOHC engine. I have dealt with a few head gasket jobs and the torque specs were somewhat higher and I never had to loosen all bolts 360 degrees in two steps. I broke a 1/2 inch drive ratchet that i needed to use a cheater bar on to get the head bolts loose because the were very tight so these specs just don,t sound right.  What do you people  think?

 

Thanks

 

 

 

No that's not correct.

 

The loosening step is correct, but the final torque sequence is not.

 

Tighten all bolts in sequence to 21 ft-lbs

tighten to 51 ft-lbs

Loosen all 180 degrees

Tighten bolts 1 & 2 to 25 ft-lbs

tighten bolts 3-6 to 11 ft-lbs

tighten all 90 degrees

tighten all an additional 90 degrees

Put a small amount of engine oil on the end of the threads and on the washer.

Thanks. Something just sounded wrong with that info.

 

Peace

Service manual actually says to loosen 180° twice ( 360° total), but there is really no need since the bolts are completely loose after the first 180°.

This is for a 2000, but same thing. It's a sohc 2.5, all the FSMs up to 2004 use the same sequence and specs.

Look on the last page of this PDF for the torque sequence and instructions
