Subject:
Lack of Power After a Period of Sustained Driving in Light Snow (Install Snow Intrusion Kit)
Models:
1996-97 Geo Tracker
1998 Chevrolet Tracker
Condition
Some customers may comment on poor performance or lack of power after a period of sustained driving in light snow.
Cause
The condition may be due to light snow entering the air cleaner through the induction system. Heavy snow is unlikely to enter, as it is too heavy to negotiate the various turns of the air path. Usually, continuous driving at highway speeds is required to cause enough snow accumulation to interfere with the intake of air to the engine. Shorter trips allow the snow to melt while the vehicle is parked. Therefore, suspect vehicles should have the air cleaner inspected for snow as soon as possible. If the vehicle is allowed to sit for a prolonged period of time, the snow will melt, thus resulting in a diagnosis of no trouble found.
Correction
A Snow Intrusion Kit (P/N 91174254) has been released which contains parts that will block the snow from traveling to the air cleaner. Follow the Service Manual procedure for removing the grill and install the Snow Intrusion Kit. See Figure 1.
