  Q: How to replace the oil cooler on Cadillac Catera?

  A:

  Vehicle suspension along with engine oil draining and oil filter housing removal serves as the initial steps for replacing the Oil Cooler. Lower the vehicle only after you have loosened all connections between the engine block and the Oil Cooler lines. Start by eliminating the intake plenum followed by the Intake Manifold then disconnect both the engine coolant temperature sender and engine Coolant Temperature Sensor from the water crossover. Remove all water crossover bolts from the Oil Cooler system in addition to upper and lower seals. Begin by loosening bolts on the Exhaust Manifold upper heat shield at its left side before removing Engine Oil Cooler outlet and inlet lines from the cooler while making note of the 4 seals' positions. A mechanic wire should be used to position the oil feed return lines safely before the Engine Oil Cooler inlet nuts and outlet nuts and cover bolts are removed to detach the Engine Oil Cooler and its cover. The installer must cleanse all sealing areas before fitting the Engine Oil Cooler. Install 2 mm (0.08 inch) of gm p/n 12346240 rtv silicone sealant in the cover groove around the Engine Oil Cooler. Apply 30 nm (22 ft. Lbs.) torque to cover bolts before installing inlet and outlet Engine Oil Cooler nuts. These nuts require a torque of 20 nm (15 ft. Lbs.). The oil feed line and return need to be repositioned before installing the Engine Oil Cooler outlet and inlet lines with 4 new seals that should be torqued to 30 nm (22 ft. Lbs.). Place the water crossover while you install the upper and lower seals before tightening the water crossover bolts to 30 nm (22 ft. Lbs.) torque settings. Reconnect the engine Coolant Temperature Sensor electrical connectors and engine coolant temperature sender electrical connectors before installing both the Intake Manifold and intake plenum. First install and tighten the Oil Cooler outlet line down to 30 nm (22 ft. Lbs.) before moving on to the Oil Cooler inlet line which needs the same 30 nm (22 ft. Lbs.) torque setting. After tightening the oil filter housing to 45 nm (33 ft. Lbs.) you must lower the vehicle to complete filling the engine oil in the crankcase.
