2007 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to remove and replace the A/C Clutch on 2007 Toyota Sequoia?

  A: Before removing and replacing the compressor and magnetic clutch you must start the engine at idle speed with the air conditioner activated for ten minutes before shutting off the engine and disconnecting the negative battery cable. The refrigeration system requires discharging of refrigerant followed by disconnecting discharge and suction hoses by removing 2 nuts which must be capped instantaneously to block entry of moisture and dirt. To start, disconnect the power connector then unfasten all 3 bolts and the single nut while also detaching the cooler bracket. The compressor must be extracted after taking off the drive belt and cooler compressor. The installation process requires mounting the cooler compressor assembly with cooler bracket using 3 bolts and nut while torquing to 47 N.m (480 kgf.cm, 35 in.lbf) and 25 N.m (255 kgf.cm, 18 in.lbf) before connector connection. A proper connection of discharge and suction hoses requires installation with 2 nuts to 10 N.m (100 kgf.cm, 7 in.lbf) by applying compressor oil to 2 new O-rings before use. Install and check the drive belt, reconnect the cable to the negative battery terminal, evacuate air from the refrigeration system, and charge the system with refrigerant, using 750 plus or minus 50g (26.45 plus or minus 1.76 oz.) for single A/C or 1050 plus or minus 50g (37.03 plus or minus 1.76 oz.) for dual A/C. Inspect for refrigerant leakage using a gas leak detector, checking the tightening torque at the joints if any leakage is found, and perform initialization, noting that some systems require this when the cable from the negative battery terminal is disconnected.
