Q: How to Replace an A/C Hose for Suction Hose on Buick Enclave?
A: Start by recovering all refrigerant before you raise and support the vehicle for replacement of the suction hose. The first step for suction hose replacement involves removing both the right front wheel house liner and the right front engine splash shield. The first step involves removing the suction hose bracket nut followed by the bracket while the suction hose/pipe bolt leads to disconnecting the suction hose/pipe from the A/C Compressor. Unfasten the txv tube nut from the suction hose/pipe and cut the hose/pipe loose from the txv tube before totally disconnecting the suction hose/pipe components. Replace all extracted o-rings from the suction hose/pipe with fresh components before attaching them to the suction hose/pipe. After installing the suction hose/pipe onto the txv tube you should fasten the txv nut with a bolt at 9 n.m (80 lb in). The suction hose/pipe should be attached to the A/C Compressor before applying the suction hose/pipe bolt which must be tightened to 9 n.m (80 lb in). Reattach the suction hose/pipe bracket with its nut before replacing both the right front engine splash shield and right front wheel house liner. After lowering the vehicle use proper equipment to evacuate and recharge the refrigerant system. The halogen leak detector (J 39400-A) should perform a leak test to inspect the fittings of this component.
Q: How to replace the A/C Hose Assembly on Buick LaCrosse?
A: The first step when replacing the compressor hose assembly requires recovering all refrigerant. The first step should be removal of the air cleaner assembly followed by disconnection of the A/C Compressor hose from the condenser after unscrewing the hose nut from the condenser. The installation begins by taking the A/C Compressor hose block between the evaporator tube and removing its hose nut and continuing to detach the hose from the tube. Start the hose assembly installation by taking off the A/C Compressor hose nut from the compressor before removing the hose from the compressor body. Discard all sealing washers. New sealing washers should be installed on the A/C Compressor hose assembly before attaching the hose to the A/C Compressor using the A/C Compressor hose nut and tightening it to 27 n.m (20 lb ft). The A/C Compressor hose assembly requires new sealing washers before connecting the A/C Compressor hose to the evaporator tube while tightening the evaporator tube nut to 16 n.m (12 lb ft). Join the condenser by attaching the A/C Compressor hose through its nut before tightening it to 16 n.m (12 lb ft). After completing the task install the air cleaner assembly and carry out an a/c system evacuation followed by recharging. Finally test for leaks using the halogen leak detector (J 39400-A).
Q: How to replace the A/C Hose Assembly on Buick Regal?
A: Staring the replacement of the A/C Compressor hose assembly requires the initial step to recover refrigerant. You must begin by taking off the right front fender upper diagonal brace next to removing the air cleaner assembly. Begin by disconnecting the A/C Compressor hose from the condenser after you have taken off the A/C Compressor hose nut . The A/C Compressor hose requires two nut removals to disconnect the hose from both its condenser and accumulator endpoints. Raise the vehicle until stable and support it while you eliminate the lower air deflector. Then discard used o-rings and sealing washers when you remove the nut from the A/C Compressor hose assembly at the A/C Compressor and separate the hose assembly. Mineral base 525 viscosity refrigerant oil serves to lubricate new o-ring seals before installation of the seal and sealing washers onto the A/C Compressor hose assembly. The hose assembly attachment must secure to the A/C Compressor rear end using the hose assembly nut until it reaches 33 n.m (24 lb ft). Accomplish the lower air deflector reinstallation before you lower the vehicle. Then attach the A/C Compressor hose nut at the accumulator and tighten it to 16 n.m (12 lb ft). Connect the A/C Compressor hose and nut to the condenser using a torque of 16 n.m (12 lb ft) and follow the same procedure for attaching the hose and nut to the condenser tube leading from the condenser to the accumulator. To complete the repair install the right front fender upper diagonal brace followed by the air cleaner assembly while the a/c system requires evacuation and recharging before testing for fittings leaks through the halogen leak detector (J 39400-A).
