Procedure
A/C Hose Assembly Modification
Note:
The A/C hose assembly is a one-piece design and incorporates a muffler to reduce compressor-refrigerant noises.
1.
Prior to performing any disassembly work, run the engine (ensure that vehicle is in Park/Neutral and emergency brake is on) and operate the A/C
system via the push-button control in the console. Observe and note the appearance of the sight glass in the receiver-drier. This information is
needed later for reassembly.
2.
Drain freon from system. Release pressure slowly to conserve refrigerant system lubricating oil.
3.
Remove air filter housing.
4.
Remove coil ignition wire from the ignition distributor cap.
5.
Remove and lay aside the ignition distributor cap (with wires attached).
6.
Remove intake manifold assembly (complete).
