COOLANT STRENGTH / TYPE
Test the strength of the coolant using an antifreeze
hydrometer.
• A 50/50 or 60/40 mixture of antifreeze and distilled
water will provide the optimum cooling, corrosion
protection, and freeze protection.
• Do not use tap water, straight antifreeze, or straight
water in the system. Tap water contains minerals and
impurities which build up in the system. Straight water
or antifreeze may cause the system to freeze, corrode,
or overheat.
