Just bought my DA a few days ago and noticed that it never stays warm when im driving. If I let it warm up while parked it gets to normal temperature until I start driving then it goes all the way to the C on the gauge. If I stop at a stoplight it starts going back up. Any ideas on what it could be? I just replaced the thermostat and that didnt help.

*Thermostat replaced
*Fans arent stuck on
*Isnt the cluster because the heat on vent is only hot when up to the middle mark

 

is your coolant temp sensor

 

Wouldnt my car still be getting warm but just showing up wrong on the cluster? It still doesnt blow hot air unless its been sitting. I start driving and the air gets colder

 

Air in the system?
Low coolant?

Full rad or half rad?

 

Air in the system would cause it to overheat. Unless you physically aren't feeling hot air come out when the car is moving, then its the temperature sensor.

 

ITS THE THERMOSTAT

its stuck open. replace it

 

Correct. Its cheap and easy to replace. Will fix the problem.

 

yup, i agree with the above posts. it sounds like your thermostat. did you replace it with a brand new one?

 

yup thermostat stuck open

 

I have the same exact problem, I'll try to replace my thermostat later today or early tommorow.

 

Yeah I replaced it with a brand new one and it didnt change anything
