Removal And Installation

RADIATOR

Removal and Installation


WARNING:
Do not remove 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 turn to release built-up pressure. Carefully remove the radiator cap by turning it all the way.
NOTE:
When removing components such as hoses, or tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

REMOVAL

1.Drain engine coolant from the radiator. Changing Engine Coolant.

CAUTION:
- Perform this step when engine is cold.
- Do not spill engine coolant on drive belt.
2.Remove air duct (inlet).
3.Disconnect the reservoir tank hose.
4.Remove radiator hoses (upper and lower).
5.Disconnect harness connectors from fan motors, and position harness aside.
6.Remove the cooling fan assembly to radiator bolts and remove cooling fan assembly.
7.Remove radiator upper mounts.
8.Move the radiator assembly to the rearward direction of vehicle, and then lift it upward to remove.

CAUTION:
Do not damage or scratch A/C condenser if equipped and radiator core when removing.

INSPECTION AFTER REMOVAL

Inspect radiator for leaks as follows:
- Apply pressure using suitable tool and Tool.





WARNING:
To prevent the risk of the hose coming undone while under pressure, securely fasten it down with a hose clamp.










- Check for leakage.

INSTALLATION

Installation is in the reverse order of removal.

CAUTION:
Do not damage or scratch A/C condenser if equipped and radiator core when installing.

INSPECTION AFTER INSTALLATION

- Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level.
- Use procedure below to check for fuel leakage.
- Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
- Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.
- Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
- Bleed air from passages in lines and hoses, such as in cooling system.
- After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
