What degree thermostat?
I just installed a manual fan control switch in my car today.

Should I just keep the stock thermostat, or do I need to replace it with a cooler one?

Thanks!
CL

Well since you have the fan switch....go with the 160!

I agree you should get the 160. Make sure you get a Hypertech or SLP stat.

Is there a difference between the Hypertech/SLP thermostat, and say, auto zone's brand?

Does GM make a 160* thermostat?

Thanks guys!

I just bought an autozone brand. I've also heard people only recommend the ones mentioned above. I dunno what the reason is though.

Do NOT use a conventional SBC thermostat in a "reverse cooled" LT1 engine. It does not have the required valve to seal the opening to control flow through the orifice in the water pump housing.

See this photo/explanation on Shoebox's Tech Pages .... always a good place to look when you have a question.

I have never heard of disadvantages to running a 160 stat. The only thing I can think of is in the winter time it takes forever for the motor to heat up if it's really cold out. That's all I know of.

I think it depends on where you live. When I lived in Florida, I put the 160 in and I feel it made a difference, althoug a small one. Just keep in mnd your environment.

Yeah your right about that. I know some people that put in 180 stats from up north when it gets really cold. Then they turn around and put the 160s back in in the summer. I guess that would work if you wanted to do it that way.

The PN for the 180* one is HYP-1008. And only $17.99 I couldn't find a 160* anywhere in Summit.

Every now and then someone will post about white goo inside their valve covers and I think that is a result of the 160 thermostat. It doesn't let the oil get hot enough to boil off moisture. You might make a bit more power but I'm not sure its worth it in the long run.

Anybody else heard of this?

So Hypertech makes a 180* and SLP makes a 160* (PN 100224--$19).

Those of you with a manual fan switch: which one did you ues?
