Question 1

How to replace the auxiliary A/C hose on GMC Acadia?

Accepted Answer

The first step to replace the auxiliary air conditioning evaporator tube requires refrigerant recovery of the system followed by raising the vehicle. The right rear inner wheelhouse liner needs to be removed if required. The auxiliary evaporator tube nut needs appropriate tools for removal before you can pull the auxiliary a/c evaporator tubes downward from the auxiliary hvac module. Start by removing the auxiliary evaporator tube clip nuts then extract the tubes from their positions. The next step involves removing the txv tube retaining nuts and the auxiliary a/c evaporator tubes from their position on the txv tube as well as condenser tube. At this point the heater/a/c tubes retaining nuts should be removed from their studs and clips which run along the frame in four different sections. Uninstall the auxiliary a/c evaporator tubes from their clamps followed by removing them from the vehicle. The replacement a/c and heater pipes arrive at customers in two separate segments which need splicing before final installation. Connect the auxiliary a/c evaporator tubes to the vehicle framework before securely mounting them on the clamps. Secure the heater/a/c tubes retaining nut to four frame retaining studs and clips by tightening it to 7 n.m (62 lb in). Install the auxiliary a/c evaporator tubes by connecting them to the txv tube and condenser tube then fasten them with retaining nuts that reach 16 n.m (12 lb ft). The hvac module requires the auxiliary a/c evaporator tubes installation together with a retaining nut that needs to be tightened to 16 n.m (12 lb ft). Secure auxiliary evaporator tubes to retaining clips while installing nuts which should be tightened to 4 n.m (35 lb in). Reassemble the right rear inner wheelhouse liner on the vehicle and lower the compartment after you recharge the refrigerant system to permitted levels and test all fittings with the halogen leak detector (J 39400-A).

Question 2

How to replace the A/C Hose on GMC Sierra 1500?

Accepted Answer

The first step to replace an evaporator tube demands proper recovery of refrigerant. Start the evaporator tube replacement by removing both the upper radiator air baffle and deflector followed by extraction of the air cleaner assembly. The next step involves removing the surge tank hold down nut while simultaneously detaching the bolt then maintaining the cooling system closed. Remove the evaporator tube nut from the evaporator before disconnection of the tube from its attachment to the evaporator. You should disconnect the auxiliary a/c tube by removing the evaporator tube nut when the system is equipped. You should first remove the evaporator tube nut from the condenser then disconnect the evaporator tube from the condenser before extracting the evaporator tube outside the vehicle. The installation process includes discarding old sealing washers while sealing all opened connections. You should connect the evaporator tube to the condenser by using new sealing washers and then install the evaporator tube nut to the condenser and tighten it to 16 nm (12 lb ft). You must install new sealing washers when connecting the evaporator tube to an auxiliary a/c tube before installing the evaporator tube nut properly and tightening it to 16 nm (12 lb ft). Stabilize the evaporator tube to the evaporator by using the evaporator tube nut which should be tightened to 16 nm (12 lb ft). Install the surge tank hold down nut and bolt before putting back the air cleaner assembly followed by installation of the upper radiator air baffle and deflector. The system evacuation process should be followed by recharging and then the j 39400-a halogen leak detector must perform a leak test on all installed components.

Question 3

How to Properly Replace the A/C Hose in LY2, LMF, L76, and L92 Models on GMC Yukon?

Accepted Answer

To change the discharge hose on vehicles ly2, lmf, l76, and l92 - first rec; the refrigerant. Disconnect the discharge hose from the A/C Compressor after looping out the discharge hose mounting bolt on the A/C Compressor. Now remove the top radiator baffle, then disconnect the discharge hose from the condenser removing the nut and the discharge hose itself. Disconnect electrical connector from a/c recirculation switch, remove discharge hose from vehicle, discard all used sealing washers and cap system openings. To install when attaching new discharge hose to the vehicle attach it to the condenser with new sealing washers. Screw the discharge hose nut to the condenser and tighten it to 16 nm (12 lb ft). Re-install the upper air baffle and also reattach the electrical connector to the a/c recirculation switch. Then attach the discharge hose to the A/C Compressor with new sealing washers and fasten it using the mounting bolt to 16 nm (12 lb ft). Lastly, evacuate and recharge the a/c system and perform a leak test on the fittings with the j 39400-a halogen leak detector.
