Allow the engine to cool before releasing the radiator cap.
Loosen the cap slowly to release any remaining pressure.
Radiator cleaning is performed while the engine is running.
Lock out and tag the controls alerting personnel that
service work is being performed. Do not remove radiator
cap unless it is required. Observe the coolant level in the
coolant recovery tank.
NOTE: Do not mix ethylene glycol and propylene glycol
antifreeze together.
1. When the engine is cold, remove radiator cap and check the
coolant level inside the radiator. Do not rely on the level of
coolant in the coolant recovery tank. Refill radiator as required.
Refer to coolant concentration table. (See page 4-94)
2. Check to make sure that coolant transfer line from the
coolant recovery tank to the radiator is free and clear of
obstructions, or is not pinched.
3. Observe the level of coolant in the coolant recovery tank.
The normal cold engine fluid level must be between
"FULL" and "LOW" marks on tank.
4. If the coolant is below the "LOW" mark, add genuine part of
50% concentration coolant to the tank.
