Installation

Install the other parts in reverse order of removal.

Perform the following :

•

Adjust a shift cable.

•

Refill engine with engine oil.

•

Refill a transaxle with fluid.

•

Refill a radiator and a reservoir tank with engine coolant.

•

Place a heater control knob on "HOT" position.

•

Clean battery posts and cable terminals and assemble.

•

Inspect for fuel leakage.

–

After assemble the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes.

–

Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.

•

Bleed air from the cooling system.

–

Start engine and let it run until it warms up. (until the radiator fan operates 3 or 4 times.)

–

Turn Off the engine. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system.
