REMOVAL

WARNING:

• Never remove reservoir tank cap when engine is hot. Serious burns could occur from high-pressure

engine coolant escaping from reservoir tank. 

• Wrap a thick cloth around the reservoir tank cap. Slowly turn it a quarter of a turn to release built-up

pressure. Then turn it all the way.

1.

Drain engine coolant from radiator. Refer to 

CO-30, "Draining"

• Never spill engine coolant on drive belts.

2.

Remove air duct (inlet). Refer to 

EM-144, "Exploded View"

.

3.

Remove reservoir tank hose at radiator side (CVT models).

4.

Disconnect connector from resistor and fan motor, and move harness to aside.

5.
