A/C Manifold and Tube

NOTE: Two different O-ring seals are used on the A/C manifold and tubes (19D734) and they are not interchangeable. One is black and is used with aluminum manifolds. The other O-ring seal is red and is used with brazed steel manifolds. Either O-ring seal must be replaced with one of the same color.

Removal

1. Discharge refrigerant from system. Observe all safety precautions. Refer to Section 12-00.

2. Remove manifold attaching bolt.

3. Disconnect pressure cut-off switch connector.

4. Remove A/C tube lock coupling clips (19E746) at the condenser tube and at the suction accumulator/drier (19C836) . Disconnect spring lock coupling at these two locations.

5. Remove the A/C manifold and tubes.

Installation

1. Position the A/C manifold and tube.

2. Connect the spring lock couplings.

3. Connect the pressure cut-off switch connector.

4. Lubricate new O-ring seals with clean refrigerant oil and position them in O-ring seal grooves of manifold. Use only the O-ring seals specified for the type of manifold being used.

5. Apply Pipe Sealant with Teflon® D8AZ-19554-A or equivalent meeting Ford specification WSK-M2G350-AZ and ESR-M18P7-A to threads of manifold retaining bolt.

   NOTE: When replacing an A/C compressor (19703) , use original manifold bolt from removed A/C compressor to attach A/C manifold and tube to new A/C compressor . DO NOT USE THE SHIPPING CAP BOLTS.

6. Position manifold with O-ring seals to A/C compressor . Install retaining bolt and tighten to 17-23 Nm (12.5-17.0 lb-ft).

7. Leak-test, evacuate and charge system following recommended procedures. Observe all safety precautions.
