ENGINE COOLING SYSTEM MAINTENANCE
NEVER remove radiator cap on an overheated engine until
engine has cooled.
Overheating is caused by a faulty cooling system or low
coolant level. Proper maintenance of cooling system will
help prevent overheating.
Park vehicle on level ground. Lower the rpm below cruising speed on an overheated
engine until temperature drops to operating range. If temperature continues to rise, shut
down completely and allow 10 minutes for engine to cool before adding coolant.
2. Open radiator cap access cover(1). Using
a rag, slowly unscrew radiator cap (2).
When steam subsides, remove cap (2).
Start engine and idle. Add coolant to top
of filler neck and replace cap (2).
4. Run engine for 1 minute longer to
eliminate any air locks; recheck coolant
level and add coolant if necessary.
Faulty Cooling System
If radiator is clogged or dirty, notify Unit maintenance.
