which is the best thermostate to use a 180 or 160 or any other one?

 

Depends.

On a computer controlled car, I'd go with a 180*, on a non CC car 160*.

180* minimum rating if you have to drive it in the winter, I see you're in NJ.
160* summer if non cc.

But, don't forget, a lower stat won't help much, if you have a temp fan switch, stock setting is around 227* or so I believe, I'd wire up a much lower one.

 

Me, I'm a crazy ****. 180* tstat, fans on all the time. The car will ride at about 180-185 all the time. With my stock fan, I noticed it wouldn't kick in until 200 or so, but I'd get the most... feel out of the car at around 180-185 and it kinda lost something above that. I hope things will be the same with the new engine. LOL

 

i have a 350 over .40 and i run a 160* with my single stock electric fan from my 2.8L. I wired my fan to run all the time but the car runs at 160* all the time, it gives me excelent performance. i do have a 3-row radiator though, but i think you would get the same out of a good stock radiator. i just upgraded cuz i didnt have a V8 one when i did the swap.

 

i used a 160 in my iroc ,180 in most all carbed engines. what exactily do you want it best for?

 

i just want my car to be cooler well actually i dont have a thermostat in my car right now nd i wanna put one in but i want one that will run cooler so im guessing the 160 is good

 

if you don't have anything in it now it'll run hot or hotter than if it had a t-stat in it, you need the restriction to allow heat to transfer to the water ,or coolant.

 

Do you find that always to be true?? B/c I suspect I don't have one in my 90 stang 4 banger, it runs very cool all the time...

 

every engine i've ever wrenched without a t stat need a restrictor to slow the water down long enough to remove heat from the engine

 

thats what i thought cause my engin is running pretty hot i think it was cooler with out it so im going to put a 160 in it

 

That would probably be fine in an LG4, but if you have the TPI engine and stock EPROM, I'd suggest the 180°F.

 

y what would be the diffrence

 

Probably, the way the computer works, you may not get out of closed loop mode, running so cool.

 

I'm running a non computer controlled carbed 350 (changed over from an LG4) and I'm running with a 180* stat cuz I want heat in the winter.

 

before i put my thermomaster chip in i went ahead and got the 160 thermostat so i wouldn't have to worry about it when i got the chip and my car ran fine
