I have a 1990 honda civic. I just changed the head gasket I need to know the head bolts torque specs thank you. It is a D 15.

Go on your computer in your browser and type in '1990 Honda Accord 2.2 4 cylinder head bolts torque specifications'. You will get back the engine bolt layout with the bolts numbered with the torque specs. You tighten the bolts according to the numbers of the bolts in the order starting with number 1 and working to the highest number.

The 12mm head bolts torque to 15 ftlbs.
the 10mm head bolts torque to 9 ftlbs.
crosshatch pattern for the sequence.

Check to make sure the plugs are tight and torqued to manufacturer's specs. Also, your Valve cover gasket(s) may need replaced.

Help need torque spec for cylinder head bolts 1986 honda civic dx 1.5 pls...

Tighten the cylinder head bolts to their final torque specification in two steps. Use a crisscross sequence starting with the bolts at the middle of the head and working toward the outer bolts.

1. Step 1: Tighten each bolt to 22 ft. lbs. (30 Nm).
   
2. Step 2: Tighten each bolt to 61 ft. lbs. (85 Nm).

Hope helps.

Hello claudian1535,

Below is an image showing the torque sequence. The torque procedure is a three step process:

Step one torque all head bolts to 14 ft.lbs.
Step two torque all head bolt to 36 ft.lbs.
Step three torque all head bolts 49 ft.lbs.




I hope this helps.

The Head bolts are located below the cams, so you have to take the cams out to get to the bolts.
The torque specs for the head bolts in sequence is 20, 40, then end at 63ft lbs. Be sure to apply anti sieze or dip the head bolts in oil, before you torque them down or you might pull out the threads. (Not a good thing TRUST ME!)
Hope this helps.

My main concern is that in 1990 Honda offered 2 engines...the D15B1 or the D16A6. I am going to assume that the engine in question is a D16A6, and the torque specs is; 47 ft/lbs for cylinder head bolts. When installing the bolts, dip them in CLEAN motor oil before inserting them into the block, and then tighten them as follows; there are 5 bolts in the front of the head, and 5 bolts in the rear. For the sake of explaination the front bolts are numbered from left to right...1,2,3,4,5 and the rear bolts are numbered from left to right...6,7,8,9,10. The correct tightening sequence for this arrangement would be; 3,8,2,9,4,7,5,6,1,10. I would recommend tightening the bolts to ~26 ft/lbs the first round, and then to 47 ft/lbs for the final round. Hope that this helps.

wow. a lot of bad information on this site. Refer to a manual for the proper torque sequence. The civic I believe is a two step torque procedure. First 22 ft lbs, than 53 ft lbs.
