RADIATOR
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.

THERMOSTAT
INSTALLATION
Installation is in the reverse order of removal.
• Use the following procedure to install the thermostat.
- Install thermostat making sure rubber ring (1) groove fits securely
to thermostat flange (A).
CAUTION:
Replace the rubber ring with a new one.
- Install thermostat (1) into the thermostat housing (2) with jiggle valve (A) facing upwards.
• Use the following procedure to install the thermostat housing.
- Securely insert the rubber ring into the mating groove of thermostat housing and install it. CAUTION:
Replace the rubber ring with a new one.
- Install the thermostat housing to the cylinder block without displacing the gasket from the gasket position.

INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• 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 leak-
age at connection points.
• Start engine. With engine speed increased, che ck 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 fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
