ISSUE: Service replacement kits for evaporator cores and evaporator cases, including case covers, are now available. An evaporator core cover must be used to seal the opening made in the top of the case when a core is replaced.
ACTION: If service is required, refer to the 1989 Thunderbird/Cougar Shop Manual, Section 36-45. Also use the following supplemental service procedure.
NOTE: WHENEVER THE EVAPORATOR CORE IS REPLACED, THE A/C ACCUMULATOR MUST ALSO BE REPLACED.
