  Q: How to Install an A/C Accumulator Without Exposing It to Moisture on Chrysler 300M?

  A:

  Having a new A/C accumulator outside for long, it can absorb moisture from the atmosphere, so avoid that. First, remove refrigerant from the A/C system by using a recovery machine, after that, take off the engine air inlet tube and the air distribution duct. After that, take out one hex bolt (8mm) that attaches the accumulator bracket and one of the nuts securing the A/C lines to the expansion valve. Pull the bracket holding the accumulator out of the strut tower and separate one A/C line connecting the accumulator to the condenser. With no more accumulator in place, transfer the small tubing from it to the expansion valve on your new accumulator and attach new O-rings. While you wait for the oil, close up the empty lines to stop moisture from getting into the system. To install, work through the steps in reverse, hold everything loosely in place first and the accumulator housing bolts should be torqued to 10 ft-lbs.

  Q: How to Service and Repair an A/C Accumulator on Chrysler 300M?

  A:

  Start the service and repair of the A/C accumulator by removing the refrigerant from the system. On vehicles equipped with either a 3.2/3.5 liter engine, take off the engine air inlet tube and the air distribution duct. After that, release the single 8mm hex bolt that holds the A/C accumulator bracket in place and remove the nut from the A/C lines at the expansion valve. First, delicately open the A/C accumulator bracket connection on the top of the strut tower, then cut a connection at the A/C accumulator and remove both pieces out of the car. Remove the small line connecting the A/C accumulator to the expansion valve before installation on the new one, always remembering to use new O-rings. Protect the liquid line fittings by plugging or capping them when the system is open. Avoid making refrigerant plumbing rough or sharp; the hose bends should be comfortable and far from the exhaust in order to prevent any damage. Pressure-test and inspect every refrigerant system connection for leaks and inspect flexible hose refrigerant lines yearly to ensure they are in good shape and correctly routed. Assemble all the pieces loosely at first, so you don't damage them and make sure to use new lubricated O-rings when you insert them. Install the little line going from the expansion valve, on the new A/C accumulator, to the refrigerant A/C accumulator and then place the new A/C accumulator inside the car. First, join the A/C line to the A/C accumulator and tighten the fastener to 13.6 N.m (10 ft. lbs.), then add the A/C accumulator bracket to the strut tower. Screw the nut that holds the A/C line to the expansion valve, using 8 N.m (6 ft. lbs.) of torque and then insert and tighten the bolt to the A/C accumulator bracket. After that, reconnect the engine air inlet tube and the air distribution duct, withdraw all the refrigerant and replenish the system.
