ScanGauge ?
Possible cooling problem & suspect calibration of the dashboard instruments.
Has anyone had success using a Scangauge or Ultragauge as a way of verifying the accuracy of the dash instruments? Yes, I know theses aftermarket gauges just read the same sensors that the OEM dash gauges read but perhaps they are more accurate.
I ask because some Forum members have spent much $$ and time chasing non-existent coolant temperature issues.
