Product Safety - Throttle Freezing

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2002-03 Chevrolet Tracker model vehicles equipped with a 2.0L four-cylinder (RPO L34 - VIN C) engine. These vehicles, when operated in extremely low temperatures (-30 degrees C. and colder) with the accelerator pedal held in one position for some time, may experience ice forming in the throttle valve that can prevent the throttle valve from closing when the driver’s foot is removed from the accelerator pedal. Increased brake pedal effort and distance would be required to stop the vehicle and the higher engine speed could result in a vehicle crash without prior warning.

Dealers are to install a new PCV hose kit.

Involved are certain 2002-03 Chevrolet Tracker model vehicles equipped with an L4 (RPO L34 - VIN C) engine and built within these VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) prior to beginning recall repairs. [Not all vehicles within the above breakpoints may be involved.]

For dealers with involved vehicles, a Campaign Initiation Detail Report containing the complete Vehicle Identification Number, customer name and address data has been prepared, and is being furnished to involved dealers. Dealers that have no involved vehicles currently assigned, will not receive a Campaign Initiation Detail Report.

The Campaign Initiation Detail Report may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.

Parts required to complete this recall are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

1. Prep the vehicle and drain the coolant.



2. Remove the PCV intake manifold vacuum hose (3).



3. Remove the upper coolant hose to the throttle body (2).



4. Install the coolant hoses (2 and 3) from the new PCV hose kit (p/n 91177471) to the pipe (1) with the yellow paint mark on top using two clamps.
5. Install the PCV Vacuum hoses (4 and 5) to the pipe (1) using two clamps.
6. Install the new hose assembly to the engine as shown.



7. Install the new clip between the coolant hose and breather hose to prevent rubbing.

The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product recall is very important in maintaining customer satisfaction.
