Engine temp My 92 Ranger 2.3L doesn't get up to operating temp at all. it might climb up to the cold line but that's it. I replaced the thermostat and the water pump is fine. this has not only me, but my diesel tech teacher, my friends, my family and most of them are very good with vehicles. so my question to you is what could it be and why

Do this test; Run engine for 5 minutes, turn off engine, grab the upper radiator hose, feel and see if it is hot then, do the same thing at lower radiator hose if it is cold, if it does, you got cooling circulation problem meaning your radiator is plug. Solution: send it out to radiator shop for flushing or install a new one.
i know i can just go get a t-flush kit and the fluid to do so. wouldnt that be better
yes, it will work just make you follow the instruction procedure
Remove the wire from the temperature sender unit and earth it out on the engine . Turn on the ignition and see if the gauge goes to overheat. If it dose replace the temperature sender unit. If it doesn't replace the gauge.
i will try that tomorrow but i have to ask, what would it be if the sensor is still good? the sensor being the issue doesnt make much sense
You are talking sensor which sends signals to the CPU ans sets the fan working , fuel mixture adhjustment etc. I am talking sender unit which is a resistance unit that controls the current flow through the gauge to give an indication of the temperature. Dead short means full current flow means overheat. No or low current means cold water or low reading
