Thermostat keeps turning off and on does anyone know what would be the source of the problem
and i did install a new one

 

maybe something with the cts

 

Don't know if it matters but it is supercharged

 

wouldn't matter but I'm not entirely sure if the cts and thermostat work together

 

Ok thanks ill look into that

 

I tried looking it up just now and I couldn't really find anything, the t stat is more of a mechanical part so it may not but I can't think of anything else that would cause that

 

yeah they do work together, I would look into trying to clean the cts maybe or just replacing it

 

What is the cts so i can get the part

 

I think CTS = Coolant Temp Sensor

 

Ok thanks

 

Ok just installed new cts in car been running about 15 min coolant won't come on still showing ---f

 

i had the same problem for a year till i finally fixed it. the seal on the thermostat went bad. replace your thermostat and you will be good to go. its not the sensor. if you want to check if its the sensor, disconnect the ecu under the hood in front of the fuse box, both connections, for 30 sec then plug it back in. when you turn the car back on your sensor should work again.

 

Not sure how unplugging the ecu will check a thermistor...
Thermostat and CTS do work together, but not directly. The ecu uses logic based on ambient air temp on start up, engine temp, vehicle speed and load over time among other inputs to code for a bad t-stat. But if you have no t-stat code, p0146 IIRC, installed the new t- stat and ECT correctly(t- stat in the propper direction... not trying to be an ass) my GUESS would be something to do with the sc build. How recent has the sc build been done, any DTC's at all? If not, I would have it scanned to see which monitors have or have not run and post back.
