ENGINE MAINTENANCE - Maintenance Requirements 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 system plugging and overheating problems. 3. Check coolant level. It should be visible through the clear plastic surge tank. 4. Add coolant as necessary until proper level is reached. Air Intake Piping Daily and refueling maintenance check for engine air intake piping. 2 This procedure should be followed as part of daily and refueling maintenance checks. This procedure should be followed as part of daily and refueling maintenance checks. NOTE 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. Perform the following steps to check the coolant level: The pressure cap (on the side of the surge tank) should NEVER be removed. The fill cap (On the top, not the side of the surge tank) is the correct fill point. 1. Check that vehicle is a on a level surface. 2. Ensure engine has not been run for several hours. Aftertreatment Exhaust Piping How to Drain Moisture from Air Tank Daily and refueling maintenance check for aftertreatment exhaust piping.
CAUTION This procedure should be followed as part of daily and refueling maintenance checks. 1. Locate the various air tanks on the vehicle 2. On the air tank, look for a valve, typically on the bottom of the tank. Due to thermal expansion the coolant level CANNOT be checked if the coolant is above ambient temperature or the en- gine has not completely cooled. The coolant level indicated on a warmed system will be inaccu- rate and can lead to low coolant conditions during cold-starts. 1. Inspect for cracks. 2. Inspect for clearance to other components (i.e. electrical harnesses, etc.). 3. Inspect hose/pipe condition – deterioration/signs of leaking. 36 Y53-1185-1E1 (04/16/18)
