Engine Cooling System
Checking Coolant Level
Check the coolant level daily before starting the
machine, or after every ten hours of use.
1. Park the machine on a level surface.
2. Perform the “Mandatory Safety Shutdown
Procedure” on page 20.
3. Wait until the engine has cooled. See
“Maintenance and Service Safety Practices” on
page 25.
4. Open the engine cover according to “Engine
Access” on page 126.
5. Model RT250:
a. Wait for the machine to cool completely.
Do not remove radiator cap when the coolant is
hot. Serious burns may occur.
b. Remove the radiator cap. Coolant level is
correct when it is level with the bottom of
the radiator fill tube.
6. Models RT175/RT210: Check the coolant level
in the expansion reservoir (R, Fig. 134). Coolant
level must be between the full (T) and low (S)
marks on the expansion reservoir. Add coolant to
the expansion reservoir as required.
IMPORTANT:
The coolant system is specifically
designed for coolant level top-off only through the
expansion reservoir. Do not add coolant directly to
the radiator.
