Always use new cylinder head bolts to ensure a leak-tightassembly.
Torque retention with used bolts can vary, which may result incoolant or
compression leakage at the cylinder head mating surface area.
18. For vehicles through 1994, tighten the cylinder head attaching bolts, in sequence,
to the following specifications:
{ Step 1: 37 ft. lbs. (50 Nm)
{ Step 2: 45 ft. lbs. (60 Nm)
{
Step 3: 52 ft. lbs. (70 Nm)
{ Step 4: 59 ft. lbs. (80 Nm)
19. For 1995 vehicles, tighten the cylinder head attaching bolts, in sequence, to the
following specifications:
{ Step 1: 15 ft. lbs. (20 Nm)
{ Step 2: 29 ft. lbs. (40 Nm)
{
Step 3: 37 ft. lbs. (50 Nm)
20. For vehicles through 1992, retighten the cylinder head bolts, in sequence, one at a
time in the following manner:
1. Long cylinder head bolts: Loosen the bolts and
back them out 2-3 turns. Retighten to 11-18 ft. lbs.
(15-25 Nm). Then tighten the bolt an additional 85-
105° and go to the next bolt in sequence.
2. Short cylinder head bolts: Loosen the bolts and
back them out 2-3 turns. Retighten to 11-18 ft. lbs.
(15-25 Nm). Then tighten the bolt an additional 65-
85°.
18. For 1993-95 vehicles, retighten the cylinder head bolts, in sequence, one at a time
in the following manner:
1. Long cylinder head bolts: Loosen the bolts and
back them out 2-3 turns. Retighten to 11-18 ft. lbs.
(15-25 Nm). Then tighten the bolt an additional 85-
95° and go to the next bolt in sequence.
2. Short cylinder head bolts: Loosen the bolt and back
them out 2-3 turns. Retighten to 7-15 ft. lbs. (10-20
Nm). Then tighten the bolt an additional 85-95°.
When cylinder head attaching bolts have been tightenedusing the above
procedures, it is not necessary to retighten bolts afterextended engine
operation. However, bolts can be checked for tightness ifdesired.
