INSTALLATION
Note to the following, and install in the reverse order of removal.

For a location with a positioning pin, insert it securely into hole of
mating part.

For a part with a specified installation orientation, refer to com-
ponent figure in EM-110, "
2WD MODEL" .

When installing engine mounting bracket on cylinder block,
tighten two upper bolts (shown as A in figure) first. Then tighten
two lower bolts (shown as B in figure). (LH and RH sides)

Tighten rear member mounting bolts in numerical order shown
in figure.
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.

Use procedure below to check for fuel leakage.
–Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil, working fluid,
fuel and exhaust gas.Slinger bolts:
