3.
Remove the under cover (A).
Tightening torque:
7.8 ~ 11.8N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7lb-ft)
Disconnect the battery negative terminal.
Remove the air cleaner assembly. (Refer to Intake and exhaust system in this group)
Remove the under cover (A).
Tightening torque:
7.8 ~ 11.8N.m (0.8 ~ 1.2kgf.m, 5.8 ~ 8.7lb-ft)
Loosen the drain plug (A), and drain the coolant.
Remove the radiator cap to speed draining.
Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.
Disconnect the over flow hose (A) from the radiator.
Remove the radiator upper hose (A) and the lower hose (B).
Install the radiator hoses as shown illustrations.
Disconnect the fan motor connector (A).
Tightening torque:
8.8 ~ 10.8 N.m (0.9 ~ 1.1 kgf.m, 6.5 ~ 7.9 lb-ft)
Disconnect the ATF cooler hoses (A). (Refer to AT group)
Remove the fan assembly (A).
Remove the horn (A), ambient sensor (B), radiator mounting bracket (C) and then remove the radiator upper mounting bracket assembly (D).
Separate the condenser from the radiator and then pull the radiator (A) upper from vehicle.
Installation is in the reverse order of removal.
Fill the radiator with coolant and check for leaks.
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 engine and let it cool dwon. Check the coolant level and add coolant if needed. This will allow trapped air to be removed from the cooling system.
Put the radiator cap on tightly, then run engine again and check for leaks.
Remove the radiator cap, wet its seal with engine coolant, then install it to pressure tester.
Apply a pressure of 93 ~ 123kPa (0.95 ~ 1.25kgf/cm², 14 ~ 19psi).
Check for a drop in pressure.
If the pressure drops, replace the cap.
Wait until engine is cool, then carefully remove the radiator cap and fill the radiator with engine coolant, then install a pressure tester on it.
Apply a pressure of 93 ~ 123kPa (0.95 ~ 1.25kgf/cm², 14 ~ 19psi).
Inspect for engine coolant leaks and a drop in pressure.
If the pressure drops, check hoses, the radiator and the water pump for leakage. If there is no leakage, inspect the heater core, the cylinder block and the cylinder head.
Remove the tester and reinstall the radiator cap.
Check for engine oil in coolant and/or coolant in engine oil.
