Cooling System Maintenance and Service

Important service notes:

• Do not operate the engine without coolant in

system.

• Do not remove the radiator cap when hot. Engine

coolant is hot and under pressure and can cause

severe burns.

• To prevent engine overheating and damage, use

the recommended anti-freeze mixture in the

cooling system.

• To prevent engine damage, do not pour cold water

into a hot engine.

• To prevent engine damage, do not use anti-freeze

with stop-leak additive(s) or put other additives in

the cooling systems.

• Cooling system capacity is approximately 1.4 L

(1.47 qt.).

Maintenance

This engine is liquid-cooled, circulating a mixture of

ethylene glycol and water for dependable operation. A

pump is used to circulate the coolant through the

system and radiator. A thermostat contained in the

system assures automatic temperature control and

rapid warm-up. Correct coolant level and cleaning any

debris accumulation from the inlet screen and radiator

surfaces are critical to insuring long life, proper system

performance, and preventing overheating. Check the

coolant level in the overflow reservoir, and clean away

any debris accumulation daily or before each use. At

the same time, inspect the hoses and all connections

for signs of leakage.

Servicing

Engine coolant should be changed every 2 years or

every 1000 hours, whichever comes first. When

changing the engine coolant, the system should also

be flushed to remove any contaminants left behind

during draining. Following are recommended

procedures for checking, draining, flushing, and filling

the cooling system.

Checking Coolant Level

The coolant level should be checked at the overflow

reservoir, located under the upper blower housing

assembly.

1. Unhook the retaining straps and remove the upper

blower housing and screen assembly. See Figures

8 and 9.

Figure 8. Unhooking Retaining Straps.

Figure 9. Removing Upper Blower Housing and

Screen Assembly.

2. Check the coolant level within the overflow

reservoir. Coolant level should be between the

''Max. Level'' and ''Min. Level'' marks on the

reservoir. See Figure 10. Do not operate the

engine with the coolant level below the ''Min.

Level'' mark.

Add coolant to the overflow reservoir as required.

Use equal parts of ethylene glycol and water only

(distilled or deionized water is recommended).
