ENGINE COOLANT CHECK
WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling
system can burn you badly. Also, you can
be burned if you spill coolant on hot engine
parts.
Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield.
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure; steam and hot liquid can come
out forcefully when the cap is loosened
slightly.
Do not add coolant further than the
MAX mark.
Note: If your vehicle is equipped with a
diesel engine, refer to the Diesel
Supplement.
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance (page 439).
Note: Make sure that the level is between
the MIN and MAX marks on the coolant
reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See Adding Engine Coolant
in this chapter.
