Adding Coolant

When adding coolant, or refilling the system, a minimum

solution of 50% recommended HOAT ethylene glycol

engine coolant (antifreeze) and distilled water should be

used. Use higher concentrations (not to exceed 70%) if

temperatures below ⫺34°F(⫺37°C) are anticipated.

Use only high purity water such as distilled or deionized

water when mixing the water/engine coolant solution.

The use of lower quality water will reduce the amount of

corrosion protection in the engine cooling system.

NOTE: It is the owner’s responsibility to maintain the

proper level of protection against freezing according to

the temperatures occurring in the area where the vehicle

is operated.

NOTE: Mixing coolant types will decrease the life of the

engine coolant and will require more frequent coolant

changes.

When additional coolant is needed to maintain the

proper level, add the recommended concentration of

antifreeze and water to the coolant bottle. Do not overfill.

NOTE: Failure to follow the antifreeze concentration

and replacement recommendations, or failure to use

antifreeze formulated to prevent corrosion of all cooling

system metals, may result in radiator plugging, overheat-

ing, or cooling system leaks such as in core hole plugs.

WARNING!

Never add coolant to the radiator when the engine is

overheated. Do not loosen or remove pressure cap to

cool an overheated engine. The coolant is under

pressure and severe scalding could result.
