substitute a known-good ECM/PCM (see page 11-7),
then recheck. If the symptom/indication goes away
with a known-good ECM/PCM, replace the original

 Use only Tracer-Stick single dose fluorescent dyecapsules from Tracerline
. Other dyes contain
solvents that may contaminate the refrigerant oil,
leading to component failure.
 Adding excessive amounts of dye can damage the compressor.
 PAG oil is water soluble, so condensation on the evaporator core or the refrigerant lines may wash the
PAG oil and fluorescent dye away from the actual
leak. Condensation may also carry dye through the
evaporator module drain.
 After checking and repairing leaks, thoroughly clean any residual dye from the areas where leaks were
found. Use GLO-AWAY dye cleaner, from Tracerline
,
and hot water to remove the dye (follow the
instructions on the bottle). Residual dye stains can
cause misdiagnosis of any future A/C system leaks.
 If any refrigerant dye contacts an exterior paint surface, remove it by doing this:
– Carefully wash the affected surfaces to remove any dirt, and to prevent paint scratching.
– Mix water and isopropyl alcohol in a 50/50 mixture.
– Soak a soft 100 percent cotton towel with the water/ alcohol mixture, and place the cloth on the affected
areas to remove the dye.
– After removing the dye with the water/alcohol- soaked cloth, carefully wash the affected areas, and
check that there is no remaining dye. 1. Connect an R-134a refrigerant recovery/recycling/
charging station (A) to the high-pressure service
port (B) and the low-pressure service port (C), as
shown, following the equipment manufacturer’s
instructions.
2. Recover refrigerant from the A/C system (see page 21-90), and evacuate the system (see page 21-91). If
the system achieves a vacuum of approximately
93.3 kPa (700 mmHg, 27.6 in.Hg) in 15 minutes, and
holds the vacuum for 15 minutes, then the system
does not have a leak at this time. If the system
cannot achieve or hold a vacuum, continue the
refrigerant leak check.
3. Open the high pressure valve to charge the system to the specified capacity.
Select the appropriate units of measure for your
refrigerant charging station.

Possible Leak Area Diagnostic Procedure with theLeak Detector Notes
21-95
4. With the engine OFF, use a halogen leak detector first to detect the leak source. Follow a continuous path in order
to ensure that you will not miss any possible leaks. Test the following areas of the system for leaks:

 





 


Service Ports Check the service ports with
the detector.
If the detector ‘‘sniffs’’ a leak,
use fluorescent dye to
confirm it. When capping the service ports, ensure that the seals
on the port caps are in place, and that the caps are
tight. The caps are used as the final seals in the
system.
Condenser If the detector ‘‘sniffs’’ a leak, use fluorescent dye to confirm it. Check for joints or connections coated with oily
dust.
Check for damaged and corroded areas.
Check all fittings, couplings, brazed/welded areas
and areas around attachment points.
Move the probe slowly (1 inch/second or less), and
keep it within 1/4 inch of the component being
checked. This maximizes the chance of detecting a
leak.
If you detect a leak, blow compressed air over the
area, then recheck for leaks. For large leaks,
clearing the area with compressed air may help
you pinpoint the leak source.
A/C Lines (Low
pressure side) Wiggle the rubber hoses
when checking crimped metal
ends.
If the detector ‘‘sniffs’’ a leak,
use fluorescent dye to
confirm it. Check all fittings, couplings, pressure switches,
brazed/welded areas, and areas around attachment
points on A/C lines and components.
Check for damaged and corroded areas.
Move the probe slowly (1 inch/second or less), and
keep it within 1/4 inch of the component being
checked. This maximizes the chance of detecting a
leak.
5. Close the quick coupler valves, then disconnect the quick couplers from the vehicle service ports.
6. Attach the universal connect set, from the Optimax Jr. Leak Detection Kit, to the service valve fitting. Close the control valve (the black knob on the connect set).
7. Attach the charging station low pressure hose quick coupler to the service valve fitting, and open the quick coupler valve. Evacuate the connect set using the charging station vacuum pump, then close the quick coupler
valve.
8. Detach the universal connect set, and install a Tracer-Stick
dye capsule between the connect set and the service
valve fitting (see the manufacturer’s instructions for more detail).
9. Attach the quick coupler on the universal connect set to the low pressure service port on the vehicle. Open the charging station low pressure hose quick coupler valve, but do not open the control valve.
10. Start the engine, and set the A/C system to MAX A/C. Open the control valve to let refrigerant and the dye enter the A/C system through the low pressure service port. Close the control valve when the Tracer-Stick
dye capsule
is empty.
11. Run the engine and A/C system for 15 minutes to thoroughly circulate the dye. Then shut the engine off, and inspect the following areas of the system for leaks.
