What are the benifits from running a low temp thermostat?

 

Able to run a little more timming. MPG will go down a little. And I seen lower Trans temps 8-10 * cooler.

 

i run a 160* stat, and besides the engine running cooler, im able to run more timing, less detonation .

 

x2 on above..

What year is your ride and mileage please.

 

If the PCM is properly tuned, mpg's will not suffer. My favorite benefit from my 160* stat is that my heat comes up very fast in the winter, since the stat opens sooner therefore allowing flow through the engine/cooling system/heater core sooner.

160* stat questions seem to pop up from time to time, and there was a big thread with much debate about the subject a few years back. The best thing that I took out of that thread is that the LS series of engines were designed to run in the 195-200 range, and seem to perform best between 180-200*. Eventually I plan to swap out my 160 for a 180 myself

 

Billy, I don't know why you haven't already. I've had the 160* on the 5.3 and now the 6.0. I've been running low to mid 170's consistently, but the real test will be in the summer. The swap is simple.

Last year upgraded to the Genesis 34" all aluminum radiator, and just this week to the 4000cfm Dorale e-fans. I threw some fresh 50/50 Dex-Cool just tonight, and I'm still at 176 at the high point, low at 168.

 

So do they make an 180 for the trucks? Or is an order thing? I've always hated Dex-cool and switch over to the green stuff..

 

Have you tried "Water Wetter"?

I use it in my '68 big block Mopar (car) and it took about 10 degrees out of the coolant mix.

Red Line Synthetic Oil - WaterWetter® Coolant Additives - WaterWetter®

 

Got any pics of that radiator? Was it a direct swap? I plan on going to the 160 myself next spring when i get back stateside. I have seen a few friends daily drive cars/trucks with the cooler stats with no issues and it seems to me that the pros outweigh the cons

 

06Sierra2. I can do that tonight when I get home. Work for you?
