COOLING SYSTEM
WARNING: Never remove the heat exchanger cap under any condition
while the engine is operating. Failure to follow these instructions could
result in damage to the cooling system, engine, or cause personal injury.
CAUTION: DO NOT add coolant to any engine that has become
overheated until the engine cools. Adding coolant to an extremely hot
engine can result in a cracked block or cylinder head.
Coolant Level
CAUTION: DO NOT mix DEX-COOL (pink/orange colored) with
traditional (green) ethylene glycol. Refer to the mixture chart on the
container for additional antifreeze protection information. DO NOT use
alcohol or methanol antifreeze, or mix them with the specified coolant.
Plain water may be used in an emergency (except in freezing
temperatures), but replace it with the specified coolant as quickly as
possible to avoid damage to the system.
KEM Equipment and General Motors recommends the use of DEX-COOL only.
Do not use alcohol or methanol antifreeze, or mix them with specified coolant.
Plain water may be used in an emergency, but replace it with the specified
coolant as quickly as possible to avoid damage to the system. Do not let the
engine run hot with only water acting as the primary coolant.
Check the coolant level of the heat exchanger daily and only when the engine is
cool. Generally a good time to do this is just prior to starting the engine for the
first time each day.
Heat Exchanger
1. Check the coolant level in the heat exchanger daily (prior to operation)
2. Make sure the coolant level is within ¾ to 1 ½ inches below the filler neck seat
3. Check the condition of the rubber seal on the coolant filler cap
4. Make sure the rubber seal is clean and free of any dirt particles.
5. Make sure the filler neck is clean then replace cap.
6. Check all hoses and connections for leaks.
7.Check all hoses and belts for cracks, frayed points, or spongy areas (replace
as necessary).
