Engine, Cooling, Fuel and Exhaust / 6-25
MAINTENANCE
7. Monitor coolant level and engine / low coolant warning lamps while running; stop as necessary to top off the
coolant. Allow the system to cool completely before removing the pressure cap.
8. After the system has cooled to room temperature, verify that the coolant level is in the surge tank sight glass.
Filling above the sight glass level with a cold engine is not recommended, since this will reduce the trapped air
space that is available for expansion as the coolant temperature increases.
System is full when no additional coolant can be added and heater lines are hot, indicating the presence of coolant.
6-19. Fuel System
6-19.1 Fuel Delivery System
Inspect fuel system for signs of damage, leaking, or chafing. Replace or repair as necessary.
6-19.2 Fuel Filters
Diesel fuel injection nozzles are manufactured to an accuracy of a few thousandths of a millimeter and are matched
precisely to each other. Impurities in the fuel can subject fuel injector components to premature damage or wear.
Replace fuel filters in accordance with the engine manufacturer’s recommendations.
6-20. Exhaust System
IMPORTANT: Periodic exhaust inspection is particularly important with all 2010 EPA & 2013 EPA diesel
engines. The muffler is part of the Diesel Particulate Filter (DPF). The exhaust pipe ahead of
the DPF will be wrapped with heat insulation. The insulation is critical to the DPF active
regeneration performance. If the insulation is damaged or missing, the internal DPF
temperature may not be high enough to burn off the particulates (soot). Likewise if pipe
clamps are loose, critical heat may escape, affect the regeneration performance and
emissions compliance.
Inspect exhaust pipe connections to check for loose clamps or corrosion. Repair or replace as necessary. Refer to
the engine manufacturer’s maintenance manual for additional information on the Diesel Oxidation Catalyst (DOC)
and Diesel Particulate Filter (DPF).
On all 2010 EPA & 2013 EPA diesel engines, the exhaust temperature can reach 1350°F during an active
regeneration cycle. An active regeneration cycle could occur automatically whenever the speedometer
indicates a speed above 5 mph. This can occur when the vehicle is in motion, or when the apparatus is
operating in stationary pump mode with an engine rpm sufficient to indicate 5 mph on the speedometer.
An exhaust temperature mitigation device is included at the tailpipe to reduce high exhaust
temperatures before the exhaust exits the tailpipe. Extreme caution should always be used when
working in the vicinity of the exhaust outlet. Failure to heed this warning may lead to personal injury or
death.
