How to replace the A/C Accumulator in the HVAC system on Buick LeSabre?

In order to replace the accumulator in the hvac system, first, use the a/c refrigerant recovery, recycling and recharging (ACR4) system (J 39500-8) to retrieve refrigerant from an a/c system. Remove the nut and cable of the positive Battery Cable from under the hood fuse block. Remove the negative Battery Cable. Then disconnect the hose of the evaporator from the cover of the accumulator and park it aside, then remove the cover of the accumulator. Then, pull the a/c compressor hose and the evaporator hose from the accumulator, and finally, pull the accumulator out of the housing. For installation, it is recommended to fill the new accumulator with the right quantity of refrigerant oil, then fitting it into the housing. Check the seal washers for damage before reinstalling the a / c lines and hoses and replace any damaged seals as needed. Mount the evaporator hose and nut to the accumulator and tighten the nut with 20 n.m (15 lb ft) and a/c compressor hose and nut with 20 n.m (15 lb ft). Connect the accumulator cover, and also the hose of the evaporator into retainer. Connect a jumper cable to another, properly charged and running automobile (other color) positive (red) one to the positive (red) battery post, jumper cable negative (black) one to battery post of the bad vehicle. Start the working automobile by turning the key to on without starting. The bad automobile should start and then be driven to a shop for diagnostics. Remove the jump cables after the car starts. 20-30 min will give the battery a 90% boost. Lastly, add charge to e-c system and check for leaks with electronic halogen leak detector (J 39400-A).

How to install the A/C Accumulator between the condenser and evaporator on the A/C evaporator tube on Buick Regal?

Before installing the A/C Accumulator which has ac p/n 15-1696 between condenser and Evaporator on the a/c Evaporator tube it is necessary to perform a leak test with the halogen leak detector (J 39400-A) on each fitting after completion. Start by extracting the refrigerant before removing the Evaporator tube from the motor vehicle to proceed. Use a tubing cutter to cut the Evaporator tube at 110 mm (4.3 in) distance from the condenser block fitting end while making sure metal shavings stay outside of the tube. Cut the tube again at 60 mm (2.4 in) while properly removing all burrs from the cut surfaces. When preparing to fit ferrules to the Evaporator tube remove the o-ring that was inside the A/C Accumulator. Fit one flare nut along with one ferrule to the Evaporator tube so the tapered end faces the flare nut before fully seating the A/C Accumulator to the tube by directing it towards the Evaporator with proper tightening to 15 n.m (11 lb ft). Seal the second half of the Evaporator tube by applying torque to both parts just like the first side. Reinstall the accumulator after the flare nuts are loosened while properly aligning the arrow marker towards the Evaporator and tightening both flare nuts to 15 n.m (11 lb ft). Installation of the Evaporator tube to the condenser tube must be done before you remove the air cleaner assembly and execute evacuation and recharging of the a/c system.
