Kyle,
My limited understanding is this... Radiator fluid flows through the heater
core to provide heat to the cab. Therefore, the higher the Rad. fluid temp.
the higher the max. temp. of the air that's blown into the cab. I recently
switched back to a 195 stat. and can notice a bit of difference from the 180.
I've heard this too and is the primary reason for switching back... Haven't
gotten any data yet as I was up hunting all last week but I'll keep ya' posted
of any change. Somebody else will have to discuss the mechanics of why MPG
should be better...
The T-Stat is a pretty simple item. Because you do the P/M by changing the
fluid, I don't see why it should ever fail as there are no significant
mechanical wear items involved with a T-Stat. I would think the only way they
would fail is because they become gummed up with crud or it was defective from
the manufacturer...

Ok......someone recently posted a 'winter and no heat' post on the DML,
while I still have heat it doesnt seem as hot as it used to be. It still
gets the truck warm, just think it used to be A LOT warmer. This may be a
tsat related problem? How does the tstat control/influence how hot the heat
gets inside my truck?
Also, and someone sent me a private email says to check my tsat, which may
cause my lower than normal gas mileage. How does the tstat affect gas
mileage???
I replaced my stock tstat at about 90,000 miles. Truck now has about 132,500
on it. How long should a tstat last for?????? I drain the radiator every
year and flush the system every other year. New radiator cap every other
year also. Any ideas.......
