Oil Cooler

The oil cooler service requires that operators position their vehicle in NEUTRAL gear on a hoist before starting work. Follow the required safety protocols to depower the fire suppression system equipped to the vehicle. The cooling system requires drainage and then removal of the oil filter while discarding it. Prior to oil filter installation users must apply engine oil on the O-ring seal. After removing the oil cooler hose bolt users should detach the oil cooler hoses from the oil filter adapter while securing them at 10 Nm (89 inch lbs.) torque before reinstalling. Any detection of metal or aluminum materials in the oil cooler or hoses will indicate possible mechanical issues. Disconnect the coolant hoses by loosening their clamps and remove the oil cooler together with the hoses while examining the oil cooler during this operation. The installation process must be followed by reversing all removal procedures while activating the fire suppression system according to requirements.

Service of the oil cooler requires a vehicle position in NEUTRAL gear and placement on a hoist. The oil filter adapter requires a drain of the cooling system before filter extraction and subsequent disposal. A new oil filter requires engine oil lubrication on its O-ring seal prior to installation. The next step involves removing the oil cooler hose bolt before separating the oil cooler hoses from the oil filter adapter until they reach a torque of 10 Nm (89 inch lbs.). When inspecting the oil cooler or its attached hoses check for signs of metal or aluminum material because it signifies mechanical problems. Unclamp the coolant hose clamps before disconnecting coolant hoses and remove the oil cooler and hoses assembly for inspection of the oil cooler for damage. Complete the installation by performing the reverse steps of removal.

Service and repair procedures for the oil cooler should start with placing the vehicle in NEUTRAL gear on a hoist. First remove the cooling system fluid while extracting the oil filter then dispose of it properly. Clean engine oil should be used to lubricate the O-ring seal before placing the new oil filter. Medium Nm force (89 inch lbs.) should be used to secure oil cooler hoses to the oil filter adapter after detaching them from the adapter. Users should exercise extreme care during inspections because metal or aluminum materials inside the oil cooler or hoses point to machine defects. The worker needs to loosen coolant hose clamps so he can disconnect the hoses then remove the oil cooler together with hoses as one unit during inspection of the oil cooler components. The installation will be finished by performing the reverse steps of removal.

The first step when servicing the oil cooler requires releasing the fire suppression system to avoid severe personal injury. Position the vehicle under a hoist system before draining the cooling system liquid. A newly manufactured oil filter needs a coating of clean engine oil before placement on its O-ring seal to ensure proper installation. Engineers building at an early stage should remove the oil cooler hose bolt before disconnecting the cooler hoses from the oil filter adapter while tightening the fittings to 10 Nm (89 lb-in) torque. Thoroughly inspect the oil cooler and hoses after hose removal because finding metal or aluminum indicates mechanical issues that threaten severe engine damage to the system. The white lines on late build coolant hoses need to be parallel with black dots on oil cooler tubes when disconnecting and installing these hoses. Clean engine oil should be applied to the O-ring between the oil filter and cooler adapter before its installation where torque should reach 46 Nm (34 lb-ft). Reverse both the removal process and power up the fire suppression system according to safety guidelines to stop serious personal injury.

Prior to maintaining the oil cooler drivers must power down any installed fire suppression system. The vehicle needs to be set to NEUTRAL position on a hoist before draining the cooling system. Industrial engine oil lubrication must be applied to the new oil filter's O-ring seal before integration into the system. The service requires you to remove the oil cooler hose bolt and disconnect the oil cooler hoses from the oil filter adapter before tightening them to 10 Nm (89 inch lbs.) when reinstalling. Metallic particles or pieces of aluminum within the oil cooler or hoses suggest the presence of mechanical problems. See and inspect the oil cooler during the procedure by first loosening two coolant hose clamps to detach the coolant hoses then remove the oil cooler and hoses as one assembly. Complete necessary inspection then repair work before doing the reverse procedure for device reinstallation and power up if the vehicle contains fire suppression system.
