How do you put freon in a 96 Avalon?

Answer 1

You would use R-134a along with a lubricant, they would be added to the low side port. You should check your PSI levels before you add any R-134a and then fill to the correct PSI level (which is determined by the current ambient temperature) You can find some helpful videos on the website icon listed below.

1. Connect manifold gauge set, then set valves closed to center hose, and disconnect vacuum pump from manifold gauge set.
2. Connect center hose of manifold gauge set to refrigerant supply.
3. Purge air from center hose by loosening hose at manifold gauge set and open refrigerant drum valve. When refrigerant escapes from hose, tighten center hose connection at manifold gauge set.
4. On vehicles so equipped, disconnect wire harness connector at clutch cycling pressure switch. Install jumper wire across terminals of connector.
5. Open manifold gauge set low side valve and allow refrigerant to enter system. Refrigerant can must be kept upright if vehicle low pressure service gauge port is not on suction accumulator/drier or suction accumulator fitting.
6. When system stops drawing refrigerant in, start engine and set control lever to A/C position and blower switch to HI position to draw remaining refrigerant into system.
7. When specified weight of refrigerant is in system, close gauge set low pressure valve and refrigerant supply valve.
8. Remove jumper wire from clutch cycling pressure switch connector and connect connector to pressure switch.
9. Operate system until pressures stabilize to check operation and system pressures. During high ambient temperatures, a high volume fan may be necessary to blow air through radiator and condenser to cool engine and prevent excessive refrigerant system pressures.
10. When charging is complete and system operating pressures are normal, disconnect manifold gauge set from vehicle and install protective caps on service gauge port valves.
