Cooling System Inspection

WARNING:

To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or hot. The coolant system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly. Failure to these instructions may result in personal injury.

CAUTION:

Check the coolant level, engine oil and transaxle fluid, top off the coolant if needed, if there is engine coolant in the engine oil or transaxle fluid the cause must be corrected and oil/fluid changed or major component damage may occur.

Inspect the coolant color:
1. If engine coolant has a clear, light green or blue indicates higher water content than required.
2. Dark brown could indicate unauthorized stopleak may have been used.
3. An iridescent sheen on top of the coolant could indicate a trace of oil is entering the system.
4. A milky brown color may indicate that either engine oil or transaxle fluid is entering the cooling system. If transaxle fluid is suspected the cause may be a leaky radiator, pressure test the cooling system. Refer to PRESSURE TEST . If engine oil is suspected the cause of the leak may be i engine.
5. If transaxle fluid is contaminated with engine coolant the cause may be a leaky radiator, pressure test the system. Refer to PRESSURE TEST .
If engine coolant appearance is good, test the engine coolant concentration with the battery and antifreeze tester:
1. Maximum coolant concentration is 60/40. (2). Minimum coolant concentrations 40/60.
Adjust coolant range and level if necessary:
1. If coolant is low, add specified coolant mixture only.
2. If the engine coolant tests to weak, add straight engine coolant until the readings are within acceptable levels.
3. If the engine coolant tests strong, remove some of the engine coolant and add water until the readings are within acceptable levels.
