Hey guys my 05 evo 8 has been having some overheating issues. Basically car is overheating after i rip when i come to stops. I have had everything checked from thermostat to head gasket checked and those all passed. When it overheats it will go up and down when i drive it. then when i let it cool down is when it starts to complete bury the needle. My tuner said there is probly 2 sensors one for my ecu and one to my dash. Also off of the computer it is reading that my temp hasnt went over 105. If anyone has some help plllease let me know .

thanks .

 

I had this problem where it would shoot straight up then get level again. I replaced the Tstat and found it was hung open. Right behing the Tstat, look straight down, thats the temp sensor. I didnt replace it because its a tight squeeze and the Tstat solved the issue.

 

Thermostat problem

 

My car started doing this today I checked my tstat and it pushes open ok what else could it be my head gasket just got replaced and it's not losing coolant started doing this in stop and go traffic any ideas I am going to buy a new tstat and coolant temp sensor

 

Anyone got ideas

 

I got an issue similar to this. the gauge stays good when driving but i park it and let the turbo timer run and it goes up then when it shuts off it dumps all the antifreeze out the overflow...

 

Replace thermostat
