Models:
2001 Oldsmobile Aurora
1999-2000 Oldsmobile Intrigue
with 3.5 L Engine (VIN H - RPO LX5)
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.
