• Q: How to replace the A/C Condenser on 2009 Buick Lucerne?

  A: To replace the air conditioning condenser, first you should recover the refrigerant. The front compartment sight shield will be removed, then the hood latch support. Take the evaporator hose by removing the nut and the hose and dispose of the sealing washers. Then, take out the suction hose bolt and suction hose, neither of which can be reused (sealing washers are discarded again). At this point, you have to remove the mounting bolts from the condenser line towards the radiator mounting bolt. Remove the condenser mounting bolts and you will then remove the condenser out of radiator retainer and then remove it from the vehicle. If you are installing a new condenser, add refrigerant oil into it. Mount the new condenser in the radiator retainer, while making sure to torque the mounting bolts worth 9 nm (80 lb in) and reuse the condenser line mounting bracket. Secure the condenser line to radiator mounting bolt when tightening at 6 nm (53 lb in) and replace with new sealing washers. Reroute the suction hose and torque the suction hose bolt to 16 nm (12 lb ft) having the help of some new seal washers. Secure both the evaporator hose by tightening the nut of the evaporator hose to 16 nm (12 lb ft). Replace the hood latch bracket, recharge the a/c system, and conduct a leak test with the j 39400-a - halogen leak detector. Finally, install the front compartment sight shield.
