So i put in a 160 tstat..burped the system and capped it off fir 30minutes..did that twice..and now my car sits at 190 as before it was 210...but after continuous driving she starts creeping to 230...my electric fans wont come on unless i turn the ac/heat on...any ideas?

usually when you install a colder thermostat, you should get a tune also, to lower your fan turn on points..this wil help better control coolant temps as your trying to do.

but why would it cause overheating..and if the pcm is still tuned to turn fans on at 225? there still not coming on at 230...gotta turn ac on just to get it back to 200-210

You need to remove that t-stat and toss it in a pot of water and turn on the heat, stand there with thermometer in it, see if it starts opening just before 160 and opens FULLY.

Lots of NEW t-stat don't work. If its not opening all the way, your flow is cut way down and you'll run hot.

Just changing to a new t-stat can't change anything with the fans, they're not related in any way.

so why did you put in a 160? It won't make the car run cooler, it just opens all the way sooner. Now you have cooling troubles and need to spend money on a Tune!

well i need to a tune anyways after full exhaust, headers, boltons, etc...i dont see how a 160 tstat is going to screw up my car...and it was running cooler sittin around 180-190 but fans wont come on to keep it there..the biggest issue is my fans only coming on when i turn my AC on...i changed the engine coolant sensor...no dice still...though i hear the temp gauges for these cars is off alot

The fans are set to come on when you turn on the A/C. When I'm sitting in traffic and my car starts to run a little hot because of lack of air forced thru the radiator, I turn on my a/c to cool the car down. It turns Both fans on.

and besides that if you have a car that is not a "Race Car" you don't need a 160 therm. No matter what the people that are selling them tell you.

so...i though fans were from the factory set to turn on when car reaches 225? my fans never come on..no matter what the temp...ur saying theyre not supposed to come on?

The fans are set to come on at a set temp. I'm not real sure exactly what that temp is so i won't guess because the Temp Police will come after me. But they should work and what I am saying is that whenever I turn on my A/C they both will come on and bring my temp down when I am sitting in Traffic. Maybe you have a blown fuse or relay. Check your owners manual to see where the fuse and/or relay is and check it out.
