will a 160*stat make that big of a diff if nelson tunes the computer?
are they worth the 30 dollars?

 

I think it's worth it!! Compared to my 03 stock stat close to 210*

 

Wouldn't hurt!! I have a 160 stat in mine but I think Allen said that this doesn't matter. He still programmed the pcm @ 180...I think???

 

I would get the 180 stat just so the antifreeze isnt flowing constantly

 

shure make alot of diffrence on a radix...20* is alot on this thing....

 

the 160 stat stays about 175-180 on a stock fan.

 

about 185* on mine...

 

Your truck will be warmer than 160 inside the block. The thermostat will only close if the coolant coming in is colder than 160. Even on 30* days my 160 thermostat with the stock electric fans set for low on at 185 and high on at 195, the idiot gauge never goes below 185. Before I changed the temp was anywhere from 200 to 240 in the stock settings. I noticed a big difference at the track in short idles that would climb to 230 in a heartbeat. Now it only gets to 195 in idle.

The thermostat is worth the money if you want the temp to be 185 not 200+++++
