48. INSTALLATION OF CYLINDER HEAD GASKET
(1)Use a scraper to clean the gasket surface of the cylinder
block.
Caution
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.
47. INSTALLATION OF CYLINDER HEAD ASSEMBLY
(1)Use a scraper to clean the gasket surface of the cylinderhead 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.
41. APPLICATION OF SEALANT TO SEMI-CIRCULAR PACK-
ING
Apply a coating of the specified sealant to the semi-circularpacking and the cylinder head to top surfaces.
Specified sealant: MOPAR Part No.4318034 or equiva-
lent
