ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed in
Scheduled Maintenance Information.
Note:
Make sure that the level is between the COLD FILL RANGE marks
on the coolant reservoir.
Note:
Coolant expands when it is hot. The level may extend beyond the
upper COLD FILL RANGE mark.
Note:
If the level is at the lower COLD FILL RANGE mark, below the
lower COLD FILL RANGE mark, or empty, add coolant immediately. See
Adding Engine Coolant
in this chapter.
The coolant concentration should be maintained within 48% to 50% which
equates to a freeze point between -30 °F (-34 °C) and -34 °F (-37 °C).
Note:
For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:
Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
WARNING:
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.
WARNING:
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.
WARNING:
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.
