ENGINE COOLANT
Checking engine coolant
• Check the level of engine coolant
when the engine is cold.
• The coolant should be at the
"cold fill level" or with the "cold
fill range" as listed on the engine
coolant reservoir.
• Refer to the Scheduled
Maintenance Guide for service
interval schedules.
Make sure to use a 50/50 mixture of engine coolant and distilled water.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you.
You can also 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.
Note: Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the recovery reservoir
when the engine is cool. Add the proper 50/50 coolant mixture to the
"cold full" level. For all other vehicles, follow these steps to add engine
coolant.
1. Turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the reservoir. Slowly turn the cap
counterclockwise until pressure begins to release.
