Oil Cooler Lines (Front): Removal

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
  1. Position the front wheels straight ahead, and remove the ignition key to lock the steering column. Disconnect the negative battery cable. Drain the cooling system. Raise and suitably support the vehicle. Place a drain pan under the vehicle to catch any fluid.
  2. Reposition the plastic retainer, in order to gain access to the lower Transmission Oil Cooler (TOC) connection. Using Transmission Cooler Quick Disconnect (J 44827), disconnect the lower TOC line from the oil cooler. Lower the vehicle; leave the vehicle on the hoist. Reposition the plastic retainer, in order to gain access to the upper TOC connection. Using transmission cooler quick disconnect, disconnect the upper TOC line from the oil cooler. Remove the air cleaner assembly.
    NOTE: Cap or tape the opening in the front evaporator tube and condenser immediately to prevent contamination.
  3. Remove the upper and lower radiator support. Recover the refrigerant from the A/C system. See GENERAL SERVICING in HVAC. Remove the front evaporator tube to condenser bolt. See Fig 1 . Disconnect the front evaporator tube from the condenser.
  4. Using a back-up wrench on the condenser fitting (2), loosen the compressor hose fitting (1) from the condenser. See Fig 2 . Disconnect the compressor hose from the condenser. See Fig 3 . Discard the O-ring seal, and cap or tape the compressor hose and condenser openings. Using Spring Hose Clamp Pliers (J 38185), release and reposition the coolant surge tank upper hose clamp away from the radiator inlet. Separate the surge tank upper hose from the radiator inlet.
  5. Using spring hose clamp pliers, release and reposition the radiator inlet hose clamp away from the radiator inlet. Separate the radiator inlet hose from the radiator inlet. Using spring hose clamp pliers, release and reposition the radiator outlet hose clamp away from the radiator outlet. Separate the radiator outlet hose from the radiator outlet. Carefully pivot the A/C condenser with the radiator forward, and tie off to support the assembly.
  6. Remove the steering column intermediate shaft lower coupling shield. Match-mark the intermediate shaft lower coupling to the Power Steering (PS) gear to ensure correct orientation upon installation. Remove the intermediate shaft lower coupling bolt. Disconnect the intermediate shaft lower coupling from the PS gear. Slide the intermediate shaft lower coupling off of the PS gear steering shaft. See Fig 4 .
  7. Remove the PS cooler retaining bolts. See Fig 5 . Remove the Brake Pressure Modulator Valve (BPMV) bracket. See appropriate ANTI-LOCK article in BRAKES. Remove the PS gear mounting bolts and nuts. Release the PS gear and cooler from the front suspension crossmember, then pull the gear and cooler forward. See Fig 6 .
  8. Remove the A/C compressor bracket. Remove the generator. See appropriate GENERATORS & REGULATORS article in ELECTRICAL. Install the Engine Support Fixture (J 41803) and the Universal Engine Support Fixture (J 28467-B) in order to support the engine. Remove the right hand engine mount (and bracket).
  9. Remove the TOC front pipe front clip. See Fig 7 . Raise the vehicle. Remove the TOC front pipe front retaining clamp bolt and retaining clamp. See Fig 8 . Remove the TOC front pipe rear retaining clamp bolt and retaining clamp. See Fig 9 . Disconnect the TOC front pipe fittings from the junction fittings at the engine flywheel housing, then cap the pipe fittings and plug the junction fittings to prevent contamination. Lower the vehicle; leave the vehicle slightly above the ground. Finesse the TOC front pipes out of the vehicle (through the top).
