PINPOINT TEST 1: LOSS OF COOLANT

PINPOINT TEST 1		LOSS OF COOLANT
STEP	INSPECTION		ACTION
1	CHECK THE ENGINE COOLANT LEVEL NOTE: Allow the engine to cool before checking the engine coolant level. Key OFF. Visually check the engine coolant level at the degas bottle Is the engine coolant level within specification?	Yes	Go to next step.
1		No	REFILL the engine coolant as necessary. Go to step 4.
2	CHECK THE DEGAS BOTTLE PRESSURE RELIEF VALVE WARNING: To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Inspect the pressure relief cap for foreign material between the sealing gasket and the diaphragm. Is the pressure relief cap OK?	Yes	Go to step 5.
2		No	CLEAN or INSTALL a new pressure relief cap. TEST the system for normal operation. Go to next step.
3	CHECK THE ENGINE COOLANT FOR INTERNAL LEAK Key OFF. Inspect the engine coolant in the degas bottle for signs of engine oil or transaxle fluid (A/T only). Is oil evident in the coolant?	Yes	If engine oil is evident, GO to ENGINE INSPECTION . If transaxle fluid is evident, REPAIR or REPLACE the radiator.
3		No	Go to next step.
4	CHECK THE ENGINE AND THE TRANSAXLE (A/T ONLY) FOR COOLANT Remove the oil level dipsticks from the engine and transaxle. Is coolant evident in the oil?	Yes	If coolant is in the engine, GO to ENGINE INSPECTION . If coolant is in the transaxle, REPAIR or REPLACE the radiator.
4		No	Go to next step.
5	PRESSURE TEST THE ENGINE COOLING SYSTEM Carry out the cooling system pressure test. Does the engine cooling system leak?	Yes	REPAIR or REPLACE components as necessary. TEST the system for normal operation.
5		No	Go to next step.
6	CHECK DEGAS BOTTLE NOTE: Allow the engine to cool before adding coolant to the degas bottle. Add coolant to the degas bottle until the fluid is between the fill marks. Does the degas bottle leak?	Yes	REPLACE the degas bottle. TEST the system for normal operation.
6		No	System is operating correctly at this time.
