Are we talking temp gauge or what turns the fans on? Yours is a 8 plug engine. If so the gauge sending unit is in block under intake. The one that turns the fan is in the upper intake between #2 and #3 injector. The is also the ECT sensor for the computer. The computer tells the IRCM on passenger fender when to pull relay in and out. Maurice

The first thing you need to do is get a mechanical (actual) reading of your coolant temp.I have a 93 LX 4 cylinder and no matter how far I drive it the gauge on the dash only ever reads at the bottom or the first line above bottom i bought the car a month ago and was told they replaced the thermostat I believe and it has a brand new radiator too so is it just a weird thing these foxes do or do I need to replace the sensor and if so where is the sensor

Who knows, your gauge might be accurate.
How do I get a reading of my coolant temp
I bought this from autozone it clearly works because it does change temp but when I point it at the radiator or the hoses it's only says like 80 degrees but when I pointed it at the exhaust manifold it read 94 degrees it was like a 25 minute drive to get where I am was that not long enough for it to warm upI would use an in-line mechanical temp gauge or a hand-held infrared temp sensor if you have access to one.
Fully warm, you should be right around 180 degrees. If that's correct, then your issue is in either the sender or the gauge itself.
Testing the sender with multi-meter isn't too difficult. I'm sure there are boobtoob videos:

What sensor is responsible for reading my temperature gauge for the coolant is it the ECT or the ACT and where are they locatedI would use an in-line mechanical temp gauge or a hand-held infrared temp sensor if you have access to one.

Is it on the driver or passenger sideneither
your gauge runs off of a sending unit, it's in the lower intake manifold.
