CANADA ONLY: AIR CLEANER FOR COLD DRIVEABILITY

VEHICLES AFFECTED: 'N' and 'X' Series

A new air cleaner assembly (P/N 25095323) for the 2.5L (RPO L68) NM5 'N' car is available for Canada only. A similar air cleaner assembly (P/N 25095101) for Canada only is currently being installed on the 2.5L (RPO LR8) NM5 'X' car. Both these air cleaner assemblies incorporate a TVS-EGR cold over-ride system which makes them unique from the Federal assemblies.

The unique air cleaner assemblies were released for Canada in an effort to assist cold driveability after an initial cold start in temperatures below 0 DEG C (32 DEG F). The TVS-ECR cold over-ride system prevents EGR until a temperature of 16 DEG C (60 DEG F) at the TVS is realized.

It should be noted that for driveability, proper installation of the hot air tube is important to ensure proper operation of the TVS-ECR cold over-ride system.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
