Installation

Installation is in the 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 and let it cool down. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system.
