INSTALLATION
1. Cylinder head gasket NO. 2 installation
(1) Operate the engine stand, and make the bank 2 side face upward.
(2) Clean the bolt holes in the cylinder block (block 2 side).
CAUTION:
To avoid erroneous tightening of the bolts, clean out the bolt holes sufficiently by blowing with compressed air to eliminate engine coolant etc.
(3) Apply THREE BOND 1217G or equivalent to both sides of a new cylinder head gasket NO. 2 as shown in the figure.
