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.
NEVER REMOVE COOLANT RECOVERY CAP WHILE ENGINE IS RUNNING OR HOT. SERIOUS INJURY MAY RESULT. PLEASE REFER TO YOUR OWNER'S GUIDE IF YOU SHOULD EVER NEED TO REMOVE RECOVERY CAP.
Locate the engine coolant reservoir and remove cap.
Add a 50/50 mixture of engine coolant and distilled water to engine coolant reservoir. Fill to marked level on reservoir.
Do not add directly to the radiator. (Straight water can be used in an emergency, but should be replaced with above 50/50 mix as soon as possible.)
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.
Use only coolant recommended in your owner's guide.
Do not use coolant additives-they may void your warranty and cause damage.
