• Q: How to replace the A/C Hose inlet on 2002 Buick Rendezvous?

  A: You must begin evaporator tube inlet replacement by removing the air cleaner assembly before you disconnect the Cruise Control Module electrical connector along with its repositioning aside and removal of mounting bracket bolts and bracket itself from the assembly. Before working on the a/c system the technician should recover the refrigerant and then remove the Wiper Motor module. After disconnecting the electrical connector from the a/c pressure sensor, the next step involves taking off both the clamp nut from the evaporator inlet tube and then extracting the sensor from its place on the tube. Disassemble the evaporator outlet tube from its connection to the txv followed by disconnecting the inlet tube from the outlet tube and immediately seal the a/c refrigerant components to avoid contamination. Next proceed to secure and cap or tape the txv before unfastening the evaporator inlet tube to condenser fitting bolt and disconnecting it from the condenser then applying caps or tape to the condenser. You need to remove the bracket bolt from the evaporator outlet tube before lifting the bracket out of the way. After that remove the evaporator inlet tube by discarding the sealing washers. The installation process requires tube and component sealing surface cleaning with a lint-free cloth followed by new sealing washer placement on the evaporator inlet tube before slowly placing it under the evaporator outlet tube bracket for securing. Attach the evaporator outlet tube bracket bolt with 5.5 n.m force (45 lb in). After that connect the evaporator inlet tube to the condenser using the corresponding bolt with 16 n.m torque (12 lb ft). After removing tape or caps from the txv and condenser, allow the evaporator inlet tube to connect with the outlet tube followed by attaching the outlet tube to the txv, apply 16 n.m (12 lb ft) torque to the outlet tube nut together with 3.3 n.m (29 lb in) torque to the inlet tube clamp nut. The procedure for installing the a/c pressure sensor at the evaporator inlet tube requires a torque of 5 n.m (44 lb in) and then plugging in its electrical connector along with reattaching the Wiper Motor module and air cleaner assembly. After mounting the cruise control assembly and tightening its bracket bolts to 6 n.m you should reconnect all wiring then evacuate the a/c system for recharge using a halogen leak detector (J 39400-A).
