MAINTENANCE
It is extremely important that when antifreeze is used, that it be mixed with water in a separate container before adding. NEVER add straight antifreeze to the radiator. Recommended mix is 50/50 lowtox (propylene glycol)
The radiator for this cooling system is provided with two drain valves; one at each end of the lower tank. When draining the system, it is necessary to open both these valves to drain the radiator completely.
Add coolant to the bottom of the fill cap again. Install radiator pressure cap. Add coolant to the proper line on the over flow tank between FULL and LOW.
Overflow bottle
When refilling the system, it is important that all trapped air be purged. The following procedure will help to insure this:
1.Make sure the engine is level. Fill the overflow reservoir up to the MAX mark with coolant mixture.
2.Slowly fill the radiator to the bottom of the filler neck with coolant mixture.
3.With radiator cap off, start the engine and let it warm up
4.Reinstall the radiator cap and run the engine a short time with the system sealed while watching the temperature gauge. If the temperature gauge goes past 230 degrees and does not drop back to approximately 190 degrees, indicating the thermostat has opened, allow the engine to cool down, check for leaks and repeat the procedure.
This is a sealed system. If it becomes necessary to add coolant mixture at a later date, check for leaks and if the overflow reservoir has not been drained completely, add coolant mixture to the reservoir only. This will help prevent air pockets in the radiator top tank and lessen the chance of introducing contaminates to the system.
