WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could
occur from high-pressure
engine coolant escaping from the radi ator. Wrap a thick cloth around the radiator cap. Slowly turn it a
quarter of a turn to release built-up pressure. Carefu lly remove radiator cap by turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Drain engine coolant from radiator. Refer to CO-8, "Draining Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove air duct. Refer to EM-26, "
Removal and Installation".
3. Disconnect radiator hose (lower) from water inlet. Refer to CO-13, "
Exploded View".
4. Remove water inlet, thermostat, and rubber ring. NOTE:
Engine coolant will leak from cylinder block, so have a receptacle ready below.

• Place a thread (A) so that it is caught in the valves of thermostat
(1). Immerse fully in a container (B) filled with water. Heat while
stirring.
• The valve opening temperature is the temperature at which the valve opens and falls from the thread.
• Continue heating. Check the full open valve lift amount.
• After checking the maximum valve lift amount, lower the water
temperature and check the valve closing temperature.
• If out of the standard specificati on range, replace the thermostat.
INSTALLATION
Installation is in the reverse order of removal.
Thermostat
• Install thermostat making sure rubber ring (1) groove fits securely
to thermostat flange (A).
CAUTION:
Do not reuse rubber ring.
• Install thermostat (2) into the cylinder block (1) with jiggle valve (A) facing upward.
Water Inlet
After installation, attach the water inlet clip (A) on the oil level gauge
guide (1) positioned at location (B) as shown.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points. Standard : Refer to
CO-25, "
Standard and Limit".

THERMOSTAT
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leaks 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.
