Removal and Installation

REMOVAL

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully remove the 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 spilling.

CAUTION:

Perform this step when the engine is cold.

Remove engine under cover. Refer to Removal and Installation.

Drain engine coolant. Refer to Draining.

Remove clip (A) of CVT water hose from bracket (1).

Remove air cleaner and air duct. Refer to Removal and Installation.

Release hose clamps (1) and (2).

CAUTION:

Never reuse hose clamps (1).

Remove CVT water hose (1) and (2) from CVT oil warmer.

Remove clip (A) of CVT water hose from bracket (1).

Release hose clamps (1).

CAUTION:

Never reuse hose clamps.

Remove CVT water hose (1) from oil cooler.

Release hose clamp (1).

Remove CVT water hose (1) from water pipe.

Remove water control valve mounting bolts (A) and then remove water control valve (1).

NOTE:

When disassembling water control valve, put matching marks on water control valve hoses, water control valve pipe, hose clamp and water control valve.

INSTALLATION

Note the following, and installation is in the reverse order of removal.

CAUTION:

• Never reuse hose clamps.

Inspection

INSPECTION AFTER REMOVAL

Water control valve

1. When coolant is cold, place dial gauge (A) on the pellet (B) of water control valve. And then measure elongation (M1) between the inlet of tube and the top of pellet.

   

2. When elongation (M1) is 39 mm (1.54 in) or less, change the water control valve because malfunction of valve contract is expected.

3. Fully immerse the water control valve (1) in a container (A). Continue heating the water while stirring.

   

4. Continue heating water 5 minutes or more after bringing the water to a boil.

5. Quickly take the water control valve out of the hot water, and measure within 10 seconds the elongation (M2) between the inlet of tube and the top of pellet after placing dial gauge (A) on the pellet (B).

   

   CAUTION:

   Carefully handle the hot water control valve to prevent from scalding.

6. Lift amount of the pellet is calculated as the following formula; M1–M2=Lift amount

   Specified lift amount: Refer to Water Control Valve .

7. When the lift amount is out of standard, replace the water control valve.

INSPECTION AFTER INSTALLATION

Start the engine, and check the joints for coolant leakage. Refer to Inspection.
