Cooling System
Maintenance
Cleaning the Radiator and the
Screen
Service Interval: Every 200 hours
Every 1,500 hours
Every 1,500 hours
To prevent the engine from overheating, the screen and
radiator must be kept clean. Normally, check the screen and
radiator daily and, if necessary, clean any debris off these
parts. However, it will be necessary to check and clean the
screen and radiator frequently in extremely dusty and dirty
conditions.
Note: If engine shuts off due to overheating, first check the
radiator and screen for excessive buildup of debris.
Clean the radiator as follows:
1. Remove the screen.
2. Working from the fan side of the radiator, blow with
low pressure (25 psi) compressed air (do not use
water). Repeat the step from the front of the radiator
and again from the fan side.
3. After the radiator is thoroughly cleaned, clean out
debris that may have collected in the channel at the
radiator base.
4. Clean and install the screen.
