Take care that no foreign material gets into the cylinder, or into coolant passages or oil passages.
(2) Make sure that the gasket has the proper identification mark for the engine.
(3) Lay the cylinder head gasket on the cylinder block with the identification mark at the front top.
56. INSTALLATION OF CYLINDER HEAD ASSEMBLY
(1) Use a scraper to clean the gasket surface of the cylin- der head assembly.
Caution
Take care that no foreign material gets into the
coolant passages or oil passages.
(2) Using the special tool and a torque wrench, tighten the bolts to the specified torque in the order shown in the
figure. (in two or three cycles.)
Caution
Install the head bolt washers as shown in the
diagram.

(1) Use a scraper to clean the gasket surface of the cylin- der head assembly.
Caution
Take care that no foreign material gets into the
coolant passages or oil passages.
(2) When installing the cylinder head bolts, check that the shank length of each bolt meets the limit. If the limit is
exceeded, replace the bolt.
Limit: Max. 99.4 mm (3.91 in.)
(3) Apply engine oil to the threaded part of the bolt and the washer.
(4) According to the tightening sequence, tighten the bolts
to the specified torque 80 Nm (58 ftlbs.).
(5) Loosen bolts completely.
(6) Torque bolts to 20 Nm (14.5 ftlbs.).
(7) Tighten bolts
l/4 turns (90”) more.
(8) Tighten bolts
l/4 turns (90”) additionally.
TSB Revision 21. CONNECTION OF HIGH-PRESSURE FUEL HOSE
When connecting the high-pressure fuel hose to the fuelrail, apply a coating of engine oil to the hose union, and in-
sert so that the O-ring is not damaged.
