3. Move probe along component approximately 25 to 50 mm (1
to 2 in)/sec.
Checking ProcedureNLHA0168S03To prevent inaccurate or false readings, make sure there is no
refrigerant vapor, shop chemicals, or cigarette 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 dis-
persed.
1. Turn engine off.
2. Connect a suitable A/C manifold gauge set to the A/C service
ports.
3. Check if the A/C refrigerant pressure is at least 345.2 kPa (3.45
bar, 3.52 kg/cm
2, 50.1 psi) above 16°C (61°F). If less than
specification, recover/evacuate and recharge the system with
the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected
since the system may not reach 345.2 kPa (3.45 bar, 3.52 kg/cm
2,
50.1 psi).
4. Conduct the leak test from the high side (compressor dis-
chargeato evaporator inletg) to the low side (evaporator drain
hosehto shaft sealk). Refer to HA-98. 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, refrigerant pressure sensor, tube
fitting, weld seams and the fusible plug mount.
+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)
With engine OFF, turn blower fan on“High”for at least 15
seconds to dissipate any refrigerant trace in the cooling unit.
Wait a minimum of 10 minutes accumulation time (refer to the
manufacturer’s recommended procedure for actual wait time)
before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least ten seconds. Use caution
not to contaminate the ptobe tip with water or dirt that may be
in the drain hose.
