Operation
The primary purpose of a cooling system is to maintain engine temperature in a range that will provide satisfactory
engine performance and emission levels under all expected driving conditions. It also provides hot coolant for heater
performance and cooling for automatic transmission oil. This is done by transferring heat from engine metal to cool-
ant, moving the heated coolant to the radiator, and then transferring the heat to the ambient air. Engine Coolant Flow Diagram - 1.6L & 1.8L & 2.0L

Cooling System Pressure Test
WARNING!
Always allow the engine to cool before opening the cooling system. Do not remove the coolant pressure relief
cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and
hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may
result in serious personal injury.
CAUTION:
Do not pressurize the cooling system beyond the maximum pressure listed in the specifications
table in this section, or cooling system components can be damaged.
1. Turn the engine off.
2. Check the engine coolant level. Adjust the coolant level as necessary.
3. Attach the pressure tester to the coolant recovery reservoir. Install a pressure test pump to the quick-connectfitting of the test adapter.
4. Pressurize the engine cooling system to 111 kPa. Observe the gauge reading for approximately 2 minutes. Pres- sure should not drop during this time. If the pressure drops within this time, inspect for leaks and repair as nec-
essary.
5. If no leaks are found and the pressure drops, the pressure relief cap may be leaking. Install a new pressure relief cap and retest the system.
6. If no leaks are found after a new pressure relief cap is installed, and the pressure drops, the leak may be inter- nal to the radiator transmission cooler (if equipped). Inspect the coolant for transmission fluid and the transmis-
sion fluid for coolant. Repair as necessary.
7. If there is no contamination of the coolant or transmission fluid, the leak may be internal to the engine. Inspect the coolant for engine oil and the engine oil for coolant.
8. Release the system pressure by loosening the pressure relief cap. Check the coolant level and adjust as nec- essary.
Cooling System Concentration Test
CAUTION:
Do not mix types of coolant, corrosion protection will be severely reduced.
Coolant concentration should be checked when any additional coolant is added to the cooling system or after a cool-
ant drain, flush and refill. The coolant mixture offers optimum engine cooling and protection against corrosion when
mixed to a freeze point of -37°C to -46°C. The use of a hydrometer or a refractometer can be used to test coolant
concentration.
