temperature gauge
the oem temp gauge is not the most reliable of things but it is with in normal running condition. on a hot day mine reaches the A in normal and i run with out a fan shroud (it keeps falling off) sure it could be cooler but for now its fine.
I believe the word you're looking for is accurate, not the most accurate as read on the scale. It is reliable, as long as you know where your truck usually runs at.
