 Subject: 180 or not?
IP: Logged
Message:
I mentioned to my parts guy that I wanted to put a 180 T-stat in my 3.9 as per the advice from this board. He said "not a good idea" because the emissions and other systems are designed to run at 195 and won't run properly at the lower temp.
Any opinions on this advice?

At 195 degrees the engine will run cleaner however it doesn't do your performance any good. A cooler engine will run MO BETTER! What do you want a cleaner engine or faster one? You will not fail any emissions test with the 180.

Your engine may not feel faster but it will run smoother. Mine does. Get the 180

I use the 180 in both my Daks with the 4.7 engines, I am glad I installed them, runs way better.

I heard a engine running 10 degrees cooler can make it last much longer before a rebuild is necessary. A above post just said "At 195 degrees the engine will run cleaner" ....
so does that mean running at 180 WILL NOT EXTEND ENGINE LIFE?

Well, I just recently put a 165 in my 3.9 and it will not go above the first line. I'll be putting a 180 soon, but, damn, I never thought it would get that cool.

Just A quick thought, running your engine at 190 will run cleaner, but would you be sacrificing the oil viscosity (sp)due to the high engine temp ? And would you be putting an extra strain on the cooling system. VS. running the 180 tstat?
