Closed cooling system includes water pump, crossflow radiator, radiator fan with electric wire, thermostat, heater core, hoses and sensors
The radiator fan with electric wire turns on when the contact temperature sensor is triggered.
On automatic transmission models, some of the fluid circulates through the transmission fluid cooler.

Checking the coolant level
Check the coolant level when the engine is cold.
Remove the cap and use the marks on the cap dipstick to determine the coolant level, which should be between the marks F and L.
Add coolant if necessary.
Coolant quality
Check for buildup of rust or scale around the cap or radiator neck.
Check that the coolant is clean and free of contaminants.
Change the coolant if necessary.
Checking the tightness of the cooling system
Remove the radiator cap.
Make sure the coolant level reaches the filler neck.
Mount the radiator cap tester to the filler neck and pressurize the cooling system to 150 kPa.
Check that the pressure in the cooling system is maintained for 2 minutes.
Do not remove the radiator cap when the engine is hot, as escaping vapors can cause severe burns.
Close the radiator cap with a thick rag and slowly unscrew the cap until steam escaping hisses.
After the steam stops escaping, slowly unscrew and remove the cap from the radiator.
Make sure the tested areas are free of moisture.
When the tester is removed, be careful not to spill coolant from the tester.
Be careful when installing and moving the appliance and do not damage the radiator filler when checking.
If not, locate the leak and fix it.
Checking the pressure radiator cap
Use the adapter to attach the radiator cap to the radiator cap tester.
Increase pressure until cap valve moves.
Main valve opening pressure: 96.1-124.5 kPa
Main valve closing pressure: 83.4 kPa
Make sure the valve opens and closes within the specified limits.
Replace the radiator cap if the valve opens and closes outside the specified limits.
Before checking, make sure that the lid is clean and free of rust and foreign matter that could interfere with its operation.
Checking the thermostat
Immerse the thermostat in a tank of water and gradually heat the water
Checking the valve opening temperature.
Standard value 82°C, full opening 95°C
Checking the height of the full opening of the valve: about 8 mm or more at 95 ° C
If the valve opening height does not meet the standard, the thermostat must be replaced
