Cylinder Head Assembly

CYLINDER HEAD





Lightly lubricate head bolts under bolt head and on threads, with engine oil and install. Using the sequence shown, tighten bolts in the following steps:

Tighten bolts 70 Nm (52 ft. lbs.).
Back off 360° in sequence.
Tighten bolts 105 Nm (77 ft. lbs.).
Re-check all bolts 105 Nm (77 ft. lbs.).
Tighten all bolts an additional 1/4 turn (90°).






BOLT RE-USABILITY





Visually inspect the cylinder head bolts for damaged threads, corroded/pitted surfaces, or a reduced diameter due to bolt stretching.

If the bolts are not damaged, their "free length" should be measured using the cap screw stretch gauge provided with the replacement head gasket. Place the head of the bolt against the base of the slot and align the bolt with the straight edge of gauge. If the end of the bolt touches the foot of the gauge, the bolt must be discarded. The maximum bolt free length is 132.1 mm (5.200 in.).

Check block surface for distortion.
Maximum variation end-to-end 0.076 mm (0.003 in.)
Maximum variation side-to-side 0.051 mm (0.002).
