•
Before removing the engine and transaxle assembly, make sure hoses and wire connectors are disconnected.
•
When remove the engine and transaxle assembly, be careful not to damage any surroundings parts or body components.
Installation
Install in the reverse order of removal.
Perform the followings :
•
Refill engine with engine oil.
•
Refill transaxle with fluid.
•
Refill radiator and reservoir tank with engine coolant.
•
Clean battery posts and cable terminals with sandpaper. Then, assemble them and apply grease to prevent corrosion.
•
Inspect for fuel leakage.
–
After assembling 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.
•
Switch heater control knob to "HOT" position.
•
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, and add coolant if needed.
This will allow trapped air to be released from the cooling system.
–
Put radiator cap on tightly, then run the engine again and check for leaks.
