Grimmspeed 160 Thermostat Works Like Advertised lol
Well thats your problem!!! CEL light came on coolant temp is not getting up to operating temp in the correct amout of time, thermostat is not even 6 months old with less then 5k on it!!
went back to stock thermostat and i'm still having problems burping or something. Tested thermostat and it opens, jiggle pin pointed up, just the lower radiator hose is cold when car is up to temp. filled engine then radiator, removed the little hose on the radiator and filled till a steady stream came out from the small hose on the passenger side. had the car tilted sideways and everything

You're doing it wrong. Search "burping"

well i did, I followed Rao in the past like 5 times 6 months ago and lower radiator hose was still cold with engine up to temp and I did test the thermostat, put it in a pot and wait for it to open before the water boils

then the other method was..fill..... mainly diff is to leave the upper radiator cap off and put a funnel on and fill it a bit. when up to temp slowly squeeze upper radiator hose to release and air bubbles, and rev engine a few times to chase out the remaining bubbles. didnt work either

*heater on full blast both times

1. Fill the radiator to the top and put on the round cap. Once it has been filled DO NOT OPEN THAT CAP AGAIN.
2. Fill the overflow up to the MIN mark.
3. Fill the tank by the turbo and leave the cap OFF.
4. Start the car, heat on max, AC off (so the fan stays off) let it IDLE until the fans turn on, which means that the thermostat is open.
5. Add coolant to top off the tank by the turbo then put the cap on and you are DONE
6. Keep an eye on the tank by the turbo for the next few days and add coolant i f necessary.
7. Also keep an eye on the over flow tank when the engine is cold and add coolant if it is below the MIN line

This works every time and is easy.

We've seen a bunch of GS T-stats fail over the years. Same with Stant and other non-OEM ones. Get the OEM ones as we've NEVER seen them fail over the 10+ years in biz.
