  Q: How to replace the A/C Accumulator on Chevrolet Malibu?

  A:

  The first step to replace the A/C accumulator requires proper refrigerant recovery before proceeding. The right front fender liner needs removal for access while immediately applying fittings that seal the condenser and evaporator opening to avoid contamination during the procedure. Before removal of the evaporator line bolt from the condenser unit handle the nuts and ferrules which will stay on the line gently. Proceed to remove the A/C accumulator from its installation. The installation requires O-rings to be placed on the liquid line followed by liquid line insertion into the A/C accumulator while tightening the nuts by hand. You should install the evaporator hose bolt and apply 25 N.m (18 lb ft) of torque to it. The A/C accumulator should have its liquid line fully inserted before applying 15 N.m (11 lb ft) torque to the accumulator nuts. Finish the process by evacuating the refrigerant system followed by charging and running a leak test on the A/C accumulator and reinstallation of the right front fender liner before lowering the vehicle.

  Q: How Must the A/C Accumulator Be Installed on the A/C Evaporator Tube to Eliminate the Need for Flushing the A/C System on Chevrolet Malibu?

  A:

  The A/C Accumulator (AC P/N-1760) needs installation on the a/c Evaporator tube (liquid line) between condenser and Evaporator to eliminate obligatory a/c system flushes. Start by recovering the a/c fluid before raising the supported vehicle. You need to remove the right front fender liner to cap or tape both condenser and Evaporator lines before possible contamination occurs. Disconnect the Evaporator line bolt at the condenser fitting after possibly wheel rotation to the right before discarding the orifice tube inside the ac p/n-1760. Cut the liquid line using the marked positions which are set 38 mm (1.5 in) apart from each other and 50 mm (2 in) below the first line hanger while ensuring all metal burrs remain outside of the line. At the condenser fitting install the Evaporator line while tightening the hose bolt to 25 n.m (18 lb ft). Take off all A/C Accumulator components consisting of nuts, ferrules and o-rings. Do not install o-rings yet at this time. Use the small end side of ferrules to push them alongside the liquid line halves until installing the line into the A/C Accumulator where it should rest at the bottom. Securely tighten the nuts before removing the accumulator from the liquid line under proper placement. Clean 525 viscosity refrigerant oil should be used to lubricate the o-rings and they should then be installed on the liquid line before reinserting it into the A/C Accumulator until it reaches the bottom. Use a torque wrench to fasten the nuts by applying 15 newton-meters while keeping the line stationary. Charge and evacuate the refrigerant system then perform fittings leak tests using j 39400-a before putting back the right front fender liner and lowering the vehicle.
