Just curious what your water temps are with a stock thermostat. Mine is ALWAYS at 210*, but I know that some years didn't really have that accurate of temp guages. BTW, I searched and didn't find much. Thanks.

 

temp gauge is a dummy from 99 on up.

 

stock LS1 thermostat is 180 isn't it??

seems like it is lower than standard SBC which is 195.

but yeah...99+ the temp guage is worthless as **** on a turtle

 

Thought so, but I couldn't remember. Thanks guys.

 

I thought we had 192* stats because you can buy 180* and 160* in the aftermarket. If you scan your PCM, you'll notice that with the stock fan settings, your coolant temp will stay in the mid-190*s on the highway and around town, it can get up into the high 220*s low 230*s depending on traffic. If I remember correctly, the stock fan settings turn on the first fan in the 220*s and the second in the low 230*s. Kinda see why they put a dummy guage in. +/- 40*s would freak me out a little if I didn't know any better.

 

The stock thermostat on my 01 Z28 was a 195F.
