    Q:
    How to replace the A/C Expansion Valve in an A/C system on Cadillac XLR? Posted by Customer
    A:
    The first step before changing the thermal expansion valve is to extract refrigerant from the a/c system. The procedure starts by taking off the rear Evaporator line assembly followed by the txv to Evaporator core mounting bolts before disconnecting the txv from the Evaporator and completely removing the piece from the vehicle. The technicians must either discard Evaporator core seal washers and preserve evaporation port cap intact or implement tape cover to protect the Evaporator core. Install new seal washers before you can connect the txv with the Evaporator core while removing protective tape or cap from the Evaporator core first. Secure the txv by tightening its mounting bolts on the Evaporator core to 7 n.m (62 lb in). After reinstallation of the rear Evaporator line assembly continue by evacuating then charging the a/c system. To conclude the process utilize the halogen leak detector (J 39400-A) to conduct fitting leak checks on the component part.

    Q:
    How to Properly Service and Replace an A/C Expansion Valve on Cadillac XLR? Posted by Customer
    A:
    Before installing the thermal expansion valve (TXV) the first step is to recover the refrigerant from the air conditioning system. The second step requires uninstalling the rear Evaporator line assembly. After recovering refrigerant you should remove the txv to Evaporator core mounting bolts then detach the txv from the Evaporator before removing it from the vehicle. The technician needs to eliminate the Evaporator core seal washers and cap installation or protect the core with tape. Begin the installation process by removing cap or tape from the Evaporator core and then add new seal washers. Before installation of the txv to the Evaporator core ensure the mounting bolts achieve a torque setting of 7 n.m (62 lb in). Replace the rear Evaporator line assembly afterward evacuate the a/c system and recharge it. A final leak test on the component fittings must be done with the use of halogen leak detector (J 39400-A).

    Q:
    How to replace the A/C Expansion Valve in an air conditioning system on Chevrolet Corvette? Posted by Customer
    A:
    A technician should start by recovering refrigerant from the air conditioning (A/C) system during replacement of the thermal expansion valve (TXV). The next step involves removing the rear Evaporator line assembly. The txv should be separated from the Evaporator by removing its mounting bolts first before disconnecting from the Evaporator core and removing it from the vehicle. You should eliminate both Evaporator core seal washers when performing this task. Alternatively you can tape off the Evaporator core. New seal washers need to be installed before removing the tape or cap that protects the Evaporator core. Install the txv to the Evaporator core by proceeding to secure the txv to Evaporator core mounting bolts to 7 n.m (62 lb in). The vehicle requires installation of the rear Evaporator line assembly along with an evacuation and recharge of the a/c system. The halogen leak detector (J 39400-A) should be utilized to perform a leak test on the component fittings.
