DANGER: Do not open the hood while the engine is running. Doing so could result in serious injury from
contact with moving parts.
Unlatch and raise the hood up to gain access the engine. Refer to
“Raising and Lowering Hood” in the “Operation” section this
manual for procedure.
The engine radiator, charge air cooler, hydraulic oil cooler and the
air conditioning condenser are in a top to bottom stacked
arrangement located in front of the engine. The cooling fan pushes
air from the front of the hood, through the coolers and out past the
engine.
Cooling Package Cleaning
Cleaning should be directed from the inside (engine) of the
cooling package toward the outside (front). Use a pressure washer
or compressed air to clean the fins. Be careful not to bend the fins.
Inspect the cooling package every 50 hours of operation for debris
and any leakage of the fittings. Repair any leaks immediately.
Straighten any dented or damaged cooling fins.

bottle is only for catching overflow from the radiator.
