Temp Gauge Problem

[Bluetta]

So, my car trys to tell me im ALWAYS overheating, which i've checked and rechecked, and im not. When i first got the car, i had a coolant flush done, which made my temp gauge go wayyy low. Eventually, i did a motor swap, which left me with no gauge, so i changed the temp sensor, on the back of the block, (which controls the gauge) which now reads too high.. Its not the actual gauge that I can tell, but do you think another sensor would fix the problem? I just sometimes worry when im stuck in traffic, and i have no way to tell. Thanks for reading!

The one in the head is for the computer so it can change fuel trims for different temps. Is that the one your your using? What engine did you swap in?

Incorrect... the sensor next to the thermostat is for the PCM and fan turn ons and such... the one that's in the back of the head is for the gauge.

Unless you have a '87-'90 digital or '96?. then you only have one sensor near the thermostat.

Not a digi dash. Just a basic plain old dash, with all my gauges the base model berettas got. Swapped an old 2.8 out, and back in with a 2.8, but from a 89 olds, which tiny minor stuff changed, but nothing big.

Really, you would know better than I would. Thought for sure it was the other way. My gauge always ran hot do to steam when the cooling system was low do to a part change. There was always coolant behind the stat, but none in front. After the level was back up the gauge went back to normal. I was just going off of what I learned from my work.

FINALLY got a sensor that works. By Standard. Only took me 3 years and like 4 sensors to get the right brand. Tried Neihoff, Borg Warner, and I cant remeber the other brand, but Standard fixed it. (at Auto Value) Last option I had was going to Napa... Ug.
