TEST OR INSPECTION
Coolant in engine oil will sometimes give engine oil a milky appearance.
Remove water pump engine oil level dipstick (WP 0243). Inspect water pump engine oil
level dipstick for signs of coolant or oil level above oil dipstick full mark.
If oil shows signs of coolant or oil level is above oil dipstick full mark,
replace water pump engine (WP 0219).
If oil does not show sign of coolant and oil level is below add mark, fill
oil to proper level.
