Owner Letter
September 1996
Dear GM Customer,
This notice is sent to inform you that General Motors is conducting a recall campaign that includes your vehicle.
General Motors has decided that certain 1996 C,K, P trucks and G-vans equipped with 7.4L engines (RPO L29 - Engine Code J) may have a condition
where the upper intake manifold gasket does not properly seal between the upper and lower intake manifolds. When this condition occurs, there may be
unmetered air pulled into the upper intake manifold that could cause rough engine idle, hesitations, hissing noise, engine stalling and/or the
illumination of the Malfunction Indicator Lamp (MIL).
To prevent this condition from occurring, your GM dealer will replace the upper manifold gaskets. This service will be performed for you at no charge.
Please contact your GM dealer as soon as possible to arrange a service date and so the dealer may order the necessary parts for the repair. Instructions
for making this correction have been sent to your dealer and parts are available. The labor time necessary to perform this service correction is
approximately 90 minutes. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.
Your GM dealer is best equipped to obtain parts and provide service to ensure that your vehicle is corrected as promptly as possible. If, however, you
take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend you
contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020 or GMC Consumer Relations office. The telephone number of the
Consumer Relations office is listed in your Warranty and Owner Assistance Information Manual.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary inspection/correction in
the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid reply card and returning it to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
