• Do not remove the radiator cap when the engine is hot. The coolant is under pressure and severe scalding could result. The engine
•
m ust be cool before servicing the cooling system.
If the engine must be running to do some work, make sure the area is well-ventilated. Never run the engine in an enclosed area.
The exhaust contains poisonous carbon monoxide gas that may cause loss of consciousness and lead to death.
•
Use only distil led water and ethylene glycol in the cooling system. A 50 - 50 mixture is recommended for maximum corro­
sion protection. Do not use alcohol-based antifreeze .
•
Add coolant at the reserve tank. Do not remove the radiator cap except to refi l l , coolant mixture testing or drain the sys-
tem, or to test the coolant mixture.
•
Avoid spilling coolant on painted surfaces .
•
After servicing the system , check for leaks with a cooling system tester.
