just got the second attarco head all buttoned up..got it back thursday night at about 10pm..it runs crazy good...only problem is...it seems to be running cold..or well..not as hot as it used to even when we first got the truck it ran hotter than this..it usually runs about 1/3 the way up the temp gauge..not it BARELY reads above the bottom (white) line on the gauge...just wondering if its bad that its running kinda cool...im guessing if its running cool then the T-stat is stuck open right?..thanks for the input..

the average temp here lately has been in the mid 20's..high teens at night...during mid day it might get..35*..maybe..dont think that matters..but o well

 

195 thermostat? heater on or off?

 

thats with heater on or off..doesnt make a difference as far as i can tell, no i think it was the 180* t-stat..just a stock replacement one from oreiley's

 

stock should be 190-195, I believe. I've got a 180 in Sin91's truck and the gauge raises to just about 1/4 the way above the first line then drops down to about 1/8 after a few minutes and stay there until on the freeway where it pops back up to about 1/4.

 

yea...now it wont even climb over the bottom line..thats with heater on/off and running at anywhere between 3000rpm and 4000rpm...so what the hell..everybody says it wont hurt anything but i aint soo sure..thanks for the help
