| I switched to a 160 deg stat this summer and it was working well keeping the temps away from the red, but now with the colder weather in canada and the gauge is only reading roughly 55 to 60 deg C. And my SES light is coming off and on perodically, and was woundering if thats too cold to be running and if it is caused by the cold engine temp. | |

| You should not run a 160 thermostat unless you have a way to reprogram the PCM for it. Switch to a 180 and your problems should go away. It can affect a lot of operating parameters, and the computer thinking the engine is not warmed up yet. | |

| I don't think there's any reason to run a 160º except for track use. Switch to 180º and maybe your SES will go out, but it could be an unrelated issue. I used to run the 160º in my Series II engine, never tripped a code or light. _________________ '05 GTO 6.0L • 6-spd • 95k miles • 0-60: 4.8s • 16.9 avg MPG • Nelson Ledges Lap: 1:26'95 Celica GT 2.2L • 5-spd • 165k miles • 0-60: yes'98 SC Riviera • 281k miles • 298 HP/370 TQ • 0-60: 5.79s • ET: 13.97 @ 99.28 • 4087 lb • 20.1 avg MPG • Nelson Ledges Lap: 1:30
