Maintenance & Adjustments

Engine

Read the Kohler engine operator’s manual for any service or

maintenance information pertaining to the engine.

Engine Coolant

Checking Engine Coolant Level

Before each use, the engine coolant level in the overflow

reservoir should be checked to ensure it is within the operating

range. Engine coolant absorbs heat from the engine and

transfers the heat to the air flowing through the radiator. If the

coolant level becomes low, the engine may overheat and could

cause severe damage to the engine.

Use a permanent type antifreeze containing corrosion and rust

inhibitors. Dilute the antifreeze with water at a 1 : 1 ratio to mix

the coolant solution (50% antifreeze : 50% water).

NOTE: Distilled water is recommended for the coolant solution

IF your tap water has a high mineral content. Minerals cause

scaling in the engine and the radiator coolant passages. System

efficiency will be greatly reduced over time and severe engine

damage may result. Refer to the antifreeze manufacturer’s

instructions for additional information on dilution procedures.

Check the coolant level when the engine is cold and the

utility vehicle is on a level surface.

Raise the hood and check the coolant level in the overflow

reservoir on the right side of the engine.

If the coolant level is below the “LOW” mark, remove the

cap from the reservoir and add coolant solution to the

“FULL” mark. Refer to Fig. 6-1.

NOTE: The cooling system is a closed type. Normally, to prevent

air from entering the system, the radiator cap should not be

removed.

If the overflow reservoir is empty, the radiator cap should be

removed and the coolant level in the radiator checked before

adding coolant to the reservoir. If necessary, first refill the system

through the radiator filler neck as follows:

WARNING: It is dangerous to remove the radiator

cap when the system is hot. Allow the system to

cool before removing the radiator cap.

Turn the radiator cap counterclockwise to the first stop to

release any pressure.

Push downward on the cap and turn counter-clockwise

until the cap stops then lift cap off.

Slowly pour coolant into the filler neck until the level

reaches the bottom of the filler neck overflow flange.

Wait a few minutes to allow as much air as possible to

escape through the filler neck, then reinstall the radiator

cap.

Fill the overflow reservoir to the “FULL” mark.

Start the engine and allow it to run for a short period. Stop

the engine.

Recheck the coolant level in the overflow reservoir and

refill as needed. Reinstall the reservoir cap.

Changing the Engine Coolant

The engine coolant should be drained and replaced with new

coolant solution every 2 years or 500 hours.

Dilute the antifreeze with water at a 1 : 1 ratio to mix the coolant

solution (50% antifreeze : 50% water).

Change the engine coolant as follows:

Drain the coolant when the engine is cold.

Place the unit on a level surface and raise the hood.

Slide the overflow reservoir upward and off the reservoir

bracket to access the radiator drain plug.

Locate the radiator drain plug in the lower right rear corner

of the radiator.

Place a suitable container beneath the drain plug and

remove the cap from the overflow reservoir.

Turn the drain plug counterclockwise to re-move. Allow

as much of the old coolant as possible to drain from the

system.
