Water Outlet Removal and Installation

Water Outlet and Water Piping: Removal and Installation

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 of a turn to release built-up pressure. Carefully remove radiator 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.

Removal

1) Drain engine coolant from the radiator. Refer to [Changing Engine Coolant] Service and Repair.

CAUTION:
- Perform this step when engine is cold.
- Do not spill engine coolant on drive belts.

2) Remove the air duct. Refer to [Air Cleaner and Air Duct: Exploded View] Exploded View.
3) Disconnect radiator hose (upper) at water outlet side. Refer to [Radiator: Exploded View] Exploded View.
4) Remove water outlet.
5) Remove throttle body coolant hose at heater pipe.
6) Remove heater core coolant hose at heater pipe.
7) Remove oil cooler coolant hose at heater pipe.
8) Remove oil level gauge and oil level gauge guide.
9) Remove exhaust manifold heat shield.
10) Remove heater pipe and O-ring.

CAUTION:
Do not reuse O-ring.

Installation

Installation is in the reverse order of removal.

- Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.

Inspection after Installation

- Check for engine coolant leaks. Refer to [Engine Coolant: System Inspection] Initial Inspection and Diagnostic Overview.
- Start and warm up engine. Visually check for engine coolant leaks. Repair as necessary.
