    Q:
    How to flush the oil cooler and replace the oil filter to prevent premature engine wear on Cadillac Escalade? Posted by Customer
    A:
    If there are foreign items in the Oil Cooler or the engine is damaged inside, flush it and change the Oil Filter during servicing. You should begin by removing the grill from the machine first. After that, remove the bolt (3) holding the hose clip, remove the nuts (2) securing the cooler lines and lastly pull the cooler lines away from the Engine Oil Cooler (1). The next step is to remove the bolts that hold the Engine Oil Cooler (3) and pull it out of the mounting brackets (4). For installation, put the Engine Oil Cooler on top of the mounting brackets and attach it to them with the Engine Oil Cooler mounting bolts. Tighten them until they reach 11 nm (97 inch lbs.). Join the cooler lines to the Engine Oil Cooler (1). Secure the fasteners at each line opening to 24 nm (18 ft. Lbs.). Place the Engine Oil Cooler hose clip and drive the bolt underneath to a tightness of 11 nm (97 inch lbs.). After everything else is complete, add oil to the engine so it reaches the proper level, start the engine and check for all leaks in the system.
