Dear General Motors Customer:

General Motors of Canada Limited has determined that all 1989-90 Trackers have been built with a positive crankcase ventilation (PCV) breather hose which may freeze during extended driving at low ambient temperatures due to its narrowness (below -20 celcius). Freezing of this passage results in loss of engine oil and engine damage.

To prevent the possibility of this condition occurring, your GM Dealer will install a new breather hose assembly. This PCV breather hose has a wider passage which prevents the hose passage from freezing.

This service will be performed for you at no charge.

Please contact your GM dealer as soon as possible to arrange a service date.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

Further assistance, if required, may be obtained from our Customer Assistance Centre, toll free, by calling 1-800-263-3777, or if you live in Quebec, 1-800-263-7854.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
