Checking Refrigerant Leaks
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is
no refrigerant vapor or tobacco smoke in the vicinity of the
vehicle. Perform the leak test in calm area (low air/wind
movement) so that the leaking refrigerant is not dispersed.
1. Turn engine off.
2. Connect a suitable A/C manifold gauge set to the A/C ser-
vice ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa
(3.452 bar, 3.52 kg/cm
2, 50 psi) above 16ÉC (61ÉF). If less
than specification, evacuate and recharge the system with
the specified amount of refrigerant.
NOTE: At temperatures below 16ÉC (61ÉF), leaks may not be
detected since the system may not reach 345 kPa
(3.452 bar, 3.52 kg/cm
2, 50 psi).
4. Conduct the leak test from the high side to the low side at
points
jathroughjn. Refer to HA-3030.
Perform a leak check for the following areas carefully. Clean
the component to be checked and move the leak detector
probe completely around the connection/component.
+Compressor
Check the fitting of high and low pressure hoses, relief valve
and shaft seal.
+Liquid tank
Check the pressure switch, tube fitting, weld seams and the
fusible plug mounts.
+Service valves
Check all around the service valves. Ensure service valve
caps are secured on the service valves (to prevent leaks).
NOTE: After removing A/C manifold gauge set from service
valves, wipe any residue from valves to prevent any
false readings by leak detector.
+Cooling unit (Evaporator)
Turn blower fan on ªHighº for at least 15 seconds to dissipate
any refrigerant trace in the cooling unit. Insert the leak detec-
tor probe into the drain hose immediately after stopping the
engine. (Keep the probe inserted for at least ten seconds.)
5. If a leak detector detects a leak, verify at least once by
blowing compressed air into area of suspected leak, then
repeat check.
6. Do not stop when one leak is found. Continue to check for
additional leaks at all system components.
7. Start engine.
8. Set the heater A/C control as follows:
a. A/C switch ON
b. Face mode
c. Recirculation switch ON
d. Max cold temperature
e. Fan speed high
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps
4 through 6 above.
SERVICE PROCEDURESMANUAL AND AUTO
HA-3031

Refrigerant leaks should be checked immediately after stop-
ping the engine. Begin with the leak detector on the high
pressure line. The pressure in the high pressure line will
gradually drop after refrigerant circulation stops and pres-
sure in the low pressure line will gradually rise, as shown in
the graph. Leaks are more easily detected when pressure is
high.
11. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component as nec-
essary.
12. Evacuate and recharge A/C system and perform the leak test
to confirm no refrigerant leaks.
13. Conduct A/C performance test to ensure system works prop-
erly.
