Retrofit Kit Installation

RETROFIT KIT INSTALLATION

1. Use the R-12 recovery/recycling station to remove the R-12 from the system.

Note
Failure to remove all the R-12 from the system will cause contamination of the R-1 34a recovery/recycling station.

2. Disconnect the R-12 recovery/recycling station.

3. 1990 - 91 Accord only: Inspect receiver line "A." If the charge valve is fitted to a block and points toward the alternator, installing the retrofit valve will leave insufficient clearance. Install a new receiver line "A" (see PARTS INFORMATION) with the charge valve mounted in the line.

4. Use a shop towel wetted with Honda brake cleaner to clean the threads on the existing valves. Apply Locktite (included in the kit) to the threads of the existing valves. Install the R-134a retrofit valves from the kit.

5. Connect the R-134a recovery/recycling station to the system. Evacuate the system.

6. Add 120 ml of PAG oil (included in the kit) to the system.

7. Determine the amount of R-134a refrigerant needed to charge the system by subtracting 50 ml (1-2/3 oz) from the system's R-12 capacity.

8. Charge the system with the proper amount of R-134a refrigerant.

9. Start the engine and let it idle. Turn the A/C system on and off several times. Listen for any abnormal noises.

10. Repeat step 9 with the engine running at 1,500 rpm and 3,000 rpm.

11. With the system on, check the cooling performance at the dashboard vents.

12. Check the high and low side pressures and compare them to the R-12 specifications. They should be slightly higher.

13. Turn off the A/C system and the engine. Disconnect the recovery/recycling station. Install the caps on the valves.

14. Place the R-134a caution label from the kit over the existing R-12 label. If the R-12 label is no longer there, place the R-134a label on the right damper housing.
