lol yes i was...hmm maybe u just have bad luck lol um otherwise like i said make sure its not stuck open, hopefully sum1 with a better idea can help me out

 

ya i am seriously starting to think its bad luck. I put in a hypertech t-stat and can tell a nice difference since it runs 20 degrees lower. Well that is when it is over 40degress outside. I honestly have no idea what it could be. Really everything runs fine even when the temp says nothing and service light comes on; the heater works etc. Just the fan is in default mode constantly running making the gasemileage crappy.

 

yep thats y i replaced mine quickly...if all else fails and u have an extra $10 just replace it again...if it still doesnt work then hopefully sum1 can give u a few more ideas

 

i sure am glad that i was searching thru the forum here cause i am having the same problem changed sensor about 2 weeks ago seemed everything was fine temp gauge worked for alittle bit and then quit again and the light came bk on i did not even think about the thermo so i am gonna try that.

 

glad our past posts could help!

 

everyone that commented on this post i appreciate your guys feedback cause it helped me diagnose and fix the same problem. right now everything is working fine and if there is anything that i can help with just let me know.

once again glad we could help

 

sorry i didnt think of thie earlier, but when the code for the thermostat sets, it kills the temp gauge, just needs the t-stat and the code cleared.

 

Cleared? And that will fix the temp gauge?

 

I think there's a Design Flaw in the Overflow tank that can cause a Low Coolant issue. My Overflow tank has a small "Gooseneck" on the side of it ... where the Coolant in the reservoir is connected to the Radiator just beneath the Radiator Cap. That "Gooseneck" section has been airbound since I have owned the car.

Today, I removed the two speed nuts holding the Tank on to the inside of the Strut Tower and inverted it to get the air bubble to release. As I did ... a quantity of Coolant rushed into the Radiator. I suspect that the air bubble kept the Fluid Level >Below< the hose opening and did not allow Coolant to return to the radiator whan the engine cooled.

I cannot say for sure, but ... it does look like the engine is runninng a tiny bit cooler after purging the air from the system.
I popped-open the Flip-top Filler Cover and laid some paper towel across the filler neck and snapped down the Lid nice and tight to keep the coolant from leaking out when the tank was held upside-down.

You can Pitch and Yaw the Tank to get all the air out as long as you don't tilt it to where the fluid will spill out the overflow ... which is only vented to the atmosphere. I'm going to put a length of hose on the overflow to vent it to the ground should it get that full ... which it shouldn't ... but, I'm **** about stuff like that and a piece of hose isn't going to upset the delicate look of the under-hood in a manner that would be unsightly.
