Lower Temp Thermostat Bad?

Is a lower temp thermostat a bad idea since these cars are designed to run with what I believe is a 180? Thanks

No, they aren't a bad idea at all. Most race ready cars run lower temp thermostats to help keep engine temps down better while racing.

Cool. So a lower temp thermostat wont mess with any warming or normal operating temp? Anything else need to be done? I dont race my cobalt, just a dd but I climb a hill every day after work that tends to kill cars and big rigs during the summer months and the occasional run-a-way trains.

No, all vehicle warmup stuff is done once the car reaches 160 degrees. So you will be fine at 160 degrees +. As far as needing anything else, you shouldn't need anything else.

Yep any time.

Banker, you should just run your turbo without coolant lines going through it and just add a turbo timer to your car to keep from burning up your turbo. Not running the coolant lines through the turbo will lower your coolant temps by about 15-20 degrees alone.

No coolant lines right now... I let it idle for at least 2 minutes wherever I stop
