Remove Engine Shrouds and Clean Cooling Fins

Service Interval: Every 80 hours

1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2.Remove cooling shroud clean-out covers from engine and clean cooling fins. Also clean dust, dirt, and oil from external surfaces of engine, which can cause improper cooling.
