How to Add Coolant to the Coolant
Surge Tank
If you have not found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible but
the coolant level is not at the FULL COLD mark on the
front of the coolant surge tank, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. See Engine Coolant on page 5-28 for

Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle's
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The
engine could catch fire and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
