CHECK ANTIFREEZE LEVEL
(Diesel Model)
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 19) 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 antifreeze specifications.
3. Check the coolant level in the radiator overflow bottle
(Figure 20). 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 antifreeze specifica-
tions.
CHANGE ANTIFREEZE
(Diesel Model)
See engine owners manual for specific antifreeze proce-
dures. The antifreeze drain valve is located at the base
of the right-hand side of the radiator.
CLEAN RADIATOR, SCREEN & OIL
COOLER
(Diesel Model)
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
