My truck temperature meter keeps going up n the red but dont overheat. whats is going on

The fan is controlled by water temp sensor to keep the temp between 160 (fan off) and 190 (on). Is the temp gauge going into the red? Is the temp sending unit for the gauge correct? The fan will run continuous with A/C on. Also check fan relay for over heating.

that is a hum dinger, largest ever posted, in one shot.
very good.!
one word , the transmission slips. (never drive a slipping tranny)
overheat indicator.! that is key.
many newer cars will change the transmission shifting any time
the engine over heats.
and overheat wins over transmission , every time.
if the engine burns up, what good is any transmission.? nada.

solve overheat first.

slip or flare.
is when the engine RPM rises fast and the car dont go faster.
SLIPS.
and slipping burns up trannyclutchs and increases the damage. inside the transmission, dont do that. dont allow it,
park it and fix it.

on some tranny there is a temperature sensor that the TCM
watches and changes shift patterns based on AFT fluid temps.
and if the ATF fluid gets too hot , it takes actions. to keep the tranny from harm.

why not get a scan too and see what DTC errors there are..
DTC, engine overheate.
DTC< tranny overheat (caused by above)

is the coolant level full and clean? if so check the thermostat, it may be sticking making the engine overheat then it opens up and the car will cool down. also make sure the cooling fans are working.

Since you have already changed everything that you have, I can not think of anything new that might cause your Jeep to overheat. Are you going by the meter in your vehicle or doing separate temperature measurements? I had a defective temperature gauge that caused me to chase my tail till I did separate measurements.

There are few possibilities that are to be checked to confirm the problem.Click the link below:-- http://technoanswers.blogspot.com/2011/06/temperature-gauge-goes-up-but-dont.html ----------- This should help.Thanks.Helpmech.

fill it up with water and get a shop to check it ASAP you dont want to overheat the engine. if you do its going to cost you.$$$$$$$$$$$$$$$

It tells you that the Temperature out side is below freezing and it comes on when it cold out side. Just to warn that could be freezing places. and sometimes it get Orange too. Hope this helps

sounds to me like the thermostat is sticking and allowing the car to overheat. with the a/c on the fan comes on and runs constantly to keep the engine cool

Your cooling system needs to be pressure checked to see where the leak is. certain auto parts stores rent out a pressure checker. make sure you have the cooling system full before doing the pressure test. check to see if you have a radiator cap and fill the system that way instead of using the resevoir

Probalby not, seeing that's what's telling your over heating. it wont be a bad idea to remove it (be carefull of hot fluid) and clean it off and put it back in. (wouldn't hurt anyways) but this problem is most likly a falty relay form the PCM to the fans. wireing might be corroed and need to be cleaned. check the fans for power and gorund with an omh meter.
