Regular Maintenance

CHECK ENGINE COOLANT LEVEL

The engine coolant level and quality should be checked before each use, when the engine is cool and off.

1.Remove the radiator pressure cap (A, Figure 17) to check the fluid level.

2.Coolant level should be 1/2” (13mm) below the bot- tom of the filler tube. If coolant level is low, add coolant until level is 1/2” (13mm) below the bottom of the filler tube. Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant specifications.

3.Check the coolant level in the radiator overflow bottle (Figure 18). If coolant level is low, add coolant until level is at the “FULL” line. Proper coolant mix is a 50/50 mixture of ethylene glycol and distilled water. See engine owners manual for engine coolant speci- fications.

CHANGE ENGINE COOLANT

See engine owners manual for specific engine coolant procedures. The drain valve is located at the base of the right-hand side of the radiator.

CLEAN RADIATOR, SCREEN & OIL COOLER

Clean the radiator, screen and oil cooler fins before each use, or as required (depending on conditions) to allow proper air-flow through radiator and hydraulic oil cooler.

1.Raise the seat plate.

2.Remove the wing bolt (E) from the oil cooler mount and pivot the oil cooler (D) forward to access the radiator screen.

3.Lift the screen keeper handles (C) up and pull for- ward. Remove the radiator screen and flush with water or blow clean with air. Flush the radiator core with water or blow clean with air. See engine owners manual for proper radiator cleaning procedures.

4.Clean all dirt, grass, and debris from the oil cooler fins.

5.Reinstall the radiator screen. Push the screen keep- er handles back and down to retain the screen.

6.Pivot the oil cooler back and reinstall the wing bolt.

WARNING

PRESSURIZED SYSTEM

Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool.

Loosen the cooling system pressure cap slowly in order the relieve the pressure.
