Condition
Some customers may comment that their vehicle displays a higher than normal temperature gauge reading or may overheat in cold weather. This will
generally occur while idling or driving slowly in traffic during colder weather, usually less than 0°C (32°F), with the heater control set to maximum heat
and fan speed. If all published diagnosis from the appropriate applicable service manual has been performed without success then an enhanced
thermostat may need to be installed.
Cause
The engine thermostat may not provide adequate coolant flow.
Correction
Perform all published diagnostics from the appropriate Service Manual and any repairs that may be indicated. If these have been performed without
success, then an enhanced thermostat should be installed. A thermostat with improved coolant flow has been developed for the 3.5 L engine applications
listed above. For complete detailed instructions on the proper installation of this thermostat, refer to the appropriate applicable GM Service Manual.
