Q: How to replace the A/C Condenser on Buick LaCrosse?
A: Starting the condenser replacement requires refrigerant recovery as the first step. The next step involves disconnecting both the Radiator and a/c line coupling where condenser tube meets the evaporator tube. The first step is to remove the a/c compressor line nut from its position on the condenser while you move the a/c compressor line out of the way before extracting the condenser from the vehicle. Throw away the o-ring seals as well as the seal washer. Apply refrigerant oil to a new condenser before you bolt it into your vehicle's frame. First attach new o-ring seals to the evaporator tube before you join the evaporator tube with the condenser tube. Install a new seal washer to the a/c compressor hose as you fit it to the condenser tube. Begin by connecting the a/c line coupling to the evaporator tube then to the condenser tube before securing the a/c compressor hose to the condenser. Tighten the a/c compressor hose block fitting nut to 17 n.m (12.5 lb ft) using a 20mm wrench or pliers that holds the A/C Condenser block fitting to stop twisting. After the installation of the Radiator complete the a/c system evacuation then recharge it while using the halogen leak detector (J 39400-A) to test for leaks.
Q: How to replace the A/C Condenser in the HVAC system on Buick LeSabre?
A: In order to replace the condenser within the hvac system, locate the source of leaks by using the halogen leak detector (J 39400-A). Start by recovering the refrigerator, then remove the upper tie bar support brace bolts at the upper tie bar, and at the support brace bolts at the headlamp and bumper fascia mounting panel, move the braces out of the way. Next, proceed with the removal of the upper radiator seal and the upper radiator mounting brackets, then proceed to disconnect the hose from the compressor and the loop from the condenser. Remove the fasteners on the side of the headlamp and the bumper fascia mounting panel to be able to lift the panel forward and have access to the condenser mounting bolts. It is very important to know that, the bolt of keeping the condenser in its connection to the radiator end tank is a special length and should be to be used only if it is re-installed again to prevent the damage of the radiator end tank. Remove both the two condenser to radiator mounting bolts; remove the two lower mounting tabs and remove the two A/C Condenser seals. Lift the condenser and take it out of the vehicle. For installation, fill the condenser with appropriate refrigerant oil, mount it into the vehicle, then insert it into the lower radiators mounting tabs by using the special length bolts for reinstallation. Torque the condenser mounting bolts to 6 n.m (53 lb in) , install the new A/C Condenser seals, replace the headlamp and bumper fascia mounting panel, fasten with bolts to 9 n.m (7 lb ft). Check seal washers for any malfunction before reinstalling the a/c lines and hoses and replace damaged seals based on what the inspection entails. Mount the evaporator hose and nut with 20 n.m (15 lb.ft) and later the compressor hose and nut with another 20n.m (15 lb.ft). Raise the upper radiator mounting brackets and their bolt up to 9 n.m (7 lb ft), followed by the upper radiator seal, front fascia to tie bar support brackets, and bolts, again to 9 n.m (7 lb ft). Finally, reinstallate front headlamps, charge the a/c system, and leak test with the halogen leak detector (J 39400-A).
Q: How to replace the A/C Condenser in the HVAC system on Buick Regal?
A: To change the condenser in the hvac unit, the refrigerant must be recovered first. Next, take away the front fender upper diagonal, the air cleaner assembly and the Radiator. Undo the condenser tube nut from the condenser and unlink the condenser tube from it. Pump the a/c system to reduce the pressure in it and then pull off the a/c compressor hose block fitting a nut and knock off the a/c compressor hose. After taking off the condenser, fit the new condenser, remember to coat the new o-ring seals with mineral base 525 viscosity refrigerant oil prior to fitting them onto the a/c compressor hose and the condenser tube. Attach the a/c compressor hose to the condenser installing the a/c compressor hose block fitting nut to the condenser. Tighten it to 16 n.m (12 lb ft). Finally, connect the condenser tube to the condenser and install the condenser tube block fitting nut and tighten it to 27 n.m (20 lb ft). Replace the Radiator and front fender upper diagonal with an air cleaner assembly. Last, evac and recharge the a/c and carry out a leak test on fittings using the halogen leak detector (J 39400-A).
