SERVICING 

Coolant does not usually need replacing. In case of larger repairs when coolant needs to be drained, new coolant 
must be used because, old has been exposed to oxidation and dirt. Flush cooling system when replacing coolant. 
To flush, fill system with clear water, and run engine for approximately 2 minutes. Drain cooling system. See 
DRAINING, FILLING & BLEEDING . Flushing system should remove most coolant residue. 

Coolant to water ratio must not exceed 60%. Frost protection and cooling efficiency will decrease if the 
percentage of coolant is too high. For coolant to water ratio, see COOLANT MIXTURE 
RECOMMENDATIONS table under COOLING SYSTEM SPECIFICATIONS. 

WARNING:

Cooling system is pressurized, when engine is at operating temperature. 
Wear gloves, and other appropriate protection. Slowly and carefully 
release system pressure, before performing any repairs.
