ISSUE:
A refrigerant leak may develop in the evaporator core tube near the spring lock coupling. The leak occurs because the carbon canister purge hose may be
routed too close and rubs against one of the evaporator core tubes and eventually wears a hole in it.
ACTION:
Install a protective sleeve for each evaporator tube, using a 1" (25.2 mm) length of heater hose. Refer to the following procedure for service details.
1.
Slit the heater hoses lengthwise and position one around each tube, close to the spring lock coupling.
2.
Secure the two hoses in position with bundling straps, as required.
3.
Be sure each sleeve is in the correct position to prevent the purge hose from rubbing against the core tubes.
4.
Reroute the canister purge hose so that it is above the evaporator core tubes and not in contact with any other vacuum line or wiring harness.
