Do u guys recommend changing the thermostat. I have thought about this and I wanted some input

 

I don't think it matters that much to be honest. I mean the car is still going to run at a certain operating temp. The whipple kit comes with a 160 degree thermostat, but my coolant temp doesn't stay there. I suppose in the winter the engine would run cooler by a few degrees over stock, but how much is 5-10 degrees going to make?

 

True. Engines are designed to run at a certain temperature. 192f which is what my 2010 had runs that temp before SC and now after SC. Many tuners won't give you full power till the enigne reaches operating temperature usually 180f+ so if your engine really ran at 165f water temperature you might not be getting full power. Plus engine wear is actually higher if the engine is too cool or too hot. Kind of like porridge it needs to be just right.

 

thanks guys I'll run with it as is

 

Just to add some info . . . whether it's good or not is up to you .

Traditionally, people would throw cooler thermostats in their cars to lower coolant temps in an effort to gain horsepower. A lot of old intake manifolds (and some new) worked as a crossover for coolant from one cylinder head to the other, so lowering coolant temps would also help lower intake temps.

However, the lower the coolant temp, the less contaminants are get burned out of the coolant and oil. As was mentioned, you don't want to be too cool or too hot. My old CTS-V was really happy in the 215 coolant range. Hot by old school standards, but in today's car world, not too bad. My suggestion is to run manufacturer recommended coolant specs. If you're driving your car in a situation where it's overheating, and nothing is really "wrong", a thermostat won't really help. You need more fans and/or cooling capacity (or independent coolers for oil). A bigger/better cooling system isn't really designed to drop temps, it's there to keep your temps stable under more extreme conditions.

Best of luck and it appears you're on the right path!
