Hey everyone I have 94 ram with a 5.2 318 my engine temp is usually at around 210 I've nvr changed the t-stat is that good or bad ? An if I should change the t-stat to a 180. If so how much would it cost me an what changes should I expect in performance an fuel economy ?

 

Flush your cooling system really well first, and make sure you have the appropriate mix for your area. (yeah, florida. I am jealous. )

Lower temp thermostat won't give you any more performance, or better fuel economy.

 

These rigs usually ran at 200 I put a 180 in mine. Didnt see any performance or economy jumps either.

 

good to know thanks for the input

 

yeah mine is right at 200 degrees 180 tsat really isnt anything but a security blanket especially for us south florida people

 

IMO in the south a 180* t-stat releives undue pressure on the cooling system making for longer life of water pump and hoses, when I went to a 180* t-stat I saw a jump in mpg"but I also did the plenum and tune up" at the same time with a CIA so I can not say that it made any diffrence in comparison to everything else.
