Cooler Thermostat

CCO · Feb 16, 2012

Anyone know the ups and downs of a cooler thermostat on our C6's?

On the surface it seems logical to cool things down somewhat for obvious (performance) reasons but what is the downside to a cool running engine?

Emissions must come into play here but what about plug fouling and SES lights that may be encountered?

I believe the stock t/stat on my C6 is around 200F and it's been discussed that a 160F can be installed.

I'm thinking that a compromise 175F would be the answer to not upset the computers, still reasonably satisfy the pollution requirements, and still get the benefits of good performance of a cooler running engine.

Thoughts.

I use a 160 on all our header installs , this will include yours Colin

So you think a 170 or 175 is out of the question?

160 is the ticket with headers and tune

You need the 180 for emissions, and don't forget horsepower is related to heat. For that reason most guys go with the 175. Personally I've always gone with 160 because I don't race my car and like the way it drives a little cooler.

True , but our 160 stat cars are passing emissions easily . Its really in the tune .

Sounds like you've got the emissions and combustion questions sorted out with that tune, Manny -- Good to hear.

I should have known.

If you let the car run a while before the test that helps. Don't just let the technician start it and test it, let it idle for a while.

I think that's standard procedure but a gentle 'reminder' would help for sure.

(just in case I keep this one long enough to get e-tested)

One more quick question: Do you reprogram the fan cut in temp and cut in speed?

Yes, fan cut in is reprogramed to coincide with the 160 stat .
