Which Temp Gauge is Right???

[Rick]

My T-link says ~35 degrees higher than my Autometer gauge.

You can kind of verify this by when the thermostat opens up. When it does, your temps should be 160 ish. (Assuming your thermostat is opening at the correct temperature). Look and see which (T-link or Auto-Meter) gauge is closer. I bet that the T-Link is.....

My Autometer mechanical gauge isn't even close...Might be because it's old....

Yep I would trust the Tlink reading...

Assuming your coolant sensor is working properly I would trust the T link. I had a similar problem caused by an eratic sensor. Mine was only abou 20 degrees difference.

I'll check the temp that the t-stat opens at. You guys didn't give me the answer I wanted to hear

Is it possible that they are taking temp reading from two different parts of the engine......cause my VDO is always higher then the T -Link?????

my VDO electrical gauge is about 4 degrees higher then the scanmaster..

My scanmaster is always 6-8 F higher them my new autometer gauge. Recheck it with another scanner and still ECM says 6-8 F highter then gauge.
