my check engine light has been on now for a while i kept checking the gas cap because that has happened before to me. so at my work we checked it with an obd comp and it came up as coolent thermostat? i have a spoon thermostat and fan switch, and i know that normaly wouldn't throw a check engine light so i am guessing i have a bad one. can any one comment?

 

What DTC Code was set??

Could be the cap, fan connection, or failure to bleed the system properly after installing the thermostat.

Utah

 

it said cooling then looked up the codes and said coolent thermostat.

 

I have had my Spoon thermo and switch for over 20,000 miles. Never a CE light.

You might want to check and make sure that one of the coolant lines from the install hasn't come lose. Also check the seal arounf the themrostat housing for leaks.

 

I think is because your thermostate open too soon and the ECU see that it's not the normal operation temperture. We had a S2000 came in to our shop with the same problem.

 

can anyone tell me the correct way to bleed the system maybe i did that wrong?
