ENGINE MAINTENANCE - Maintenance Requirements Chassis Fuel Filter / Water Separator Daily and refueling maintenance check for the chassis fuel filter/water separator. 2. Inspect for clearance to other components (i.e. electrical harnesses, etc.). 3. Inspect hose/pipe condition – deterioration/signs of leaking. system plugging and overheating problems. This procedure should be followed as part of daily and refueling maintenance checks. Perform the following steps to check the coolant level: 1. Check that vehicle is a on a level surface. 2. Ensure engine has not been run for several hours. 2 This procedure should be followed as part of daily and refueling maintenance checks. 1.
Drain trapped water (if equipped). Cooling Fan Daily and refueling maintenance check for engine cooling fan. Air Intake Piping Daily and refueling maintenance check for engine air intake piping. This procedure should be followed as part of daily and refueling maintenance checks. 1. Inspect for cracks. 2. Inspect for clearance to other components. This procedure should be followed as part of daily and refueling maintenance checks. 1. Inspect hose/pipe condition – deterioration/signs of leaking. 2. Inspect hose clamps for tightness and pinching/cutting of hoses. 3. Inspect clearance to other components. 4. Check air restriction gauge.
CAUTION Due to thermal expansion the coolant level CANNOT be checked if the cool- ant is above ambient temperature or the engine has not completely cooled. The coolant level indicated on a warmed system will be inaccurate and can lead to low coolant conditions dur- ing cold-starts. Coolant Level Daily and refueling maintenance check for engine coolant level. Replacement or top up coolant should have the same antifreeze concentration and corrosion inhibitor content as the original coolant in the cooling system. If operating in sub-freezing conditions, a 60/40 mix of antifreeze and distilled water may be substituted.
Always dilute antifreeze to the correct concentration based on freeze protection before adding it to the cooling system. Adding or using 100% antifreeze in a cooling system may result in cooling Aftertreatment Exhaust Piping Daily and refueling maintenance check for aftertreatment exhaust piping. 3. Check coolant level. It should be visible through the clear plastic surge tank. 4. Add coolant as necessary until proper level is reached. This procedure should be followed as part of daily and refueling maintenance checks. 1. Inspect for cracks. See Radiator Fill Procedure on page 66 for coolant level indentifieres for different surge tanks. 30 Y53-1166-1G1 (08/2018)
