K 2500 Truck 4WD V8-379 6.2L DSL VIN C FI (1989)
Vehicle Limited Warranty, dealers are instructed to proceed as follows:
Important:
On vehicles equipped with A/C systems NOT produced by GM (i.e., rear A/C systems in van conversions), consult the manufacturer of that A/C
system for retrofit guidelines.
^
Offer the customer the option of repairing and recharging the system with R12, or retrofitting after repair and recharging with R-134a at no
additional charge.
^
Provide the owner with, and review the information contained in, the "Converting Your Auto Air Conditioning System to Use the New
Refrigerant" brochure. (Brochure, Form GM-0011, can be ordered free of charge from GM Fulfillment HQ, Phone 1-800-269-5100).
^
Record the customer's choice on the repair order and, as with all properly completed repair orders, ask the customer to sign on the appropriate
line acknowledging the repairs requested.
^
Under no circumstances should the retrofit to R-134a be performed unless the customer has had the option explained prior to repair. Once the
vehicle has been retrofitted to R-134a, a significant expenditure would be incurred to go back to R-12, in the event the customer has changed
his/her mind.
THIS OFFER APPLIES ONLY TO VEHICLES REQUIRING A/C REFRIGERANT SYSTEM REPAIRS UNDER THE TERMS OF THE NEW
VEHICLE LIMITED WARRANTY. It is not a special policy, and any existing deductibles still apply. This is simply an option being offered to
the customer during the warranty period at this time. GM reserves the right to terminate this offer at any time.
If the R-12 refrigerant system does not require discharging for a warranty repair, but the customer requests a retrofit to R-134a, the retrofit
WOULD BE PERFORMED AT THE CUSTOMER'S EXPENSE, EVEN DURING THE WARRANTY PERIOD.
2.
Customer Paid Retrofitting Costs
If the customer requests a retrofit to R-134a, for a specific vehicle whose retrofit parts and procedures have been released in this bulletin, the
customer would be expected to pay the costs to retrofit under the following conditions:
^
The vehicle is no longer covered by the terms of the New Vehicle Limited Warranty.
^
The vehicle is covered by warranty, but the repair covered under the warranty does not require evacuating and recharging the refrigerant
system.
3.
Labor Time Information
For Vehicles Repaired Under Warranty: Use existing labor operations for correcting the original condition. The quantity of R-134a used should be
charged to the normal labor operation (not D4500), just as if it were R-12.
Use D4500, 0.3 HR., to charge for parts and labor, for all of the following items:
^
Additional time for recovery of R-12 to meet SAE standards;
^
Install high and low side service port converter fittings;
^
Add PAG or V5 retrofit oil;
^
Complete label information and install.
Add 0.2 hours to D4500 for installation of the HPCOS.
Use T5321, 0.3 HR., for the Pontiac Bonneville hood seal installation.
ANY PARTS OR LABOR TIME OTHER THAN THOSE LISTED ABOVE SHOULD BE CHARGED TO THE REGULAR LABOR
OPERATION CORRESPONDING TO THE ORIGINAL CONDITION THAT 1S BEING REPAIRED.
