Checking and Adding Engine Coolant

The internal combustion process of an engine produces a tremendous amount of heat–more than enough to damage your engine if unprotected. That’s where engine coolant comes in. Maintaining coolant level is vital to the well being of your car or truck.

CAUTION: NEVER REMOVE COOLANT RECOVERY OR RADIATOR CAP WHILE ENGINE IS RUNNING OR HOT. SERIOUS INJURY MAY RESULT. PLEASE REFER TO YOUR OWNER’S GUIDE FOR INSTRUCTIONS ON CHECKING AND ADDING COOLANT

Important: Please read and understand all procedures and precautions in your Owner’s Guide regarding this process.

1. When the engine is cold, open hood, locate engine coolant reservoir and remove cap.
2. Use only the coolant recommended in your Owner’s Guide.
3. Add a 50/50 mixture of engine coolant and distilled water to engine coolant reservoir. Fill to the cold-fill level or within the cold-fill range as listed on the engine coolant reservoir.
4. Do not add directly to the radiator. (Straight water can be used in an emergency, but should be replaced with 50/50 mixture of the coolant as soon as possible.)
5. If coolant is added, check the level a few more times. You may need to add a bit more, as the level may change. Continue to “top it off” until level remains consistent.
6. Use only coolant recommended in your Owner’s Guide.
7. Do not use extra coolant inhibitors or additives–they may void your warranty and cause engine damage.
