The receiver/drier should be replace whenever there is a replacement of the condenser. To start with, the some steps that ought to be followed are to first cycle the air conditioning system. Secondly, remove the negative cables from the battery then remove the grille and the front bumper as well. Disconnect the electric connections of the dual-pressure switch and the condenser fan. Refrigerant lines must be disconnected and this is done by unscrewing the screws required to release the condenser; the condenser is mounted on the car by four clamps, one from each comer. Unbolt and unbend the condenser brackets together with the auxiliary electric fan which should not be used. Gently raise the condenser out of the vehicle and seal the lines so that dust and moisture cannot get in. In cases where the original condenser will be reused position it with the line fittings on top to prevent oil drainage. Upon purchasing a new condenser you must introduce one ounce of such refrigerant oil before installation. Lastly, replace the components in the same sequence with the rubber insulator pads properly positioned and get the system back to the shop which discharged it to get a vacuum, recharge and leakage test.
