160 thermostat for the 2004+ trucks

[tbyrne]

I've confirmed that the 160 thermostats that we have in stock will work on the 2004-'05 GM trucks powered by the 4.8, 5.3 and 6.0 motors. These low-temp thermostats dramatically reduce your engine’s operating temperatures, improving performance and extending component longevity. They’re easy to install that will also fit all 2004+ GTO and Corvette applications.

 

The part number and price is - 100228 - $19.99. No 180 thermostats are available at this time.

how about the 8.1L's? I heard that 160^ was to low for the 8.1L's and to stick with the 180^. What do you think or have on your 8.1L's?

You probably need all the heat you can get up there so I'd keep the stock thermostat! I run a 160 in my HD and haven't had any problems.
