Kia Rio: Radiator: Inspection

Radiator Cap Testing

1.	Remove the radiator cap, wet its seal with engine coolant, then install it to pressure tester.

2.	Apply a pressure of 93 ~ 123kPa (0.95 ~ 1.25kgf/cm², 14 ~ 19psi).

3.	Check for a drop in pressure.

4.	If the pressure drops, replace the cap.

Radiator Leakage Test

1.	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.

2.	Apply a pressure of 93 ~ 123kPa (0.95 ~ 1.25kgf/cm², 14 ~ 19psi).

3.	Inspect for engine coolant leaks and a drop in pressure.

4.	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.

Fan Motor

1.	Disconnect the fan motor connector from the resistor.

2.	Connect the battery voltage to the "+" terminal and ground to "-" terminal.

3.	Check the cooling fan motor operates well.

1. Disconnect the battery negative terminal. Tightening torque (-) terminal (without battery sensor): 7.8 ~ 9.8N.m (0.8 ~ 1.0 ...
