I want to install a 180 thermostat, but was wondering what kind I should go with. I've heard reviews of some that are cheap and only last a year. I want one that will last and isn't a POS.

I've seen a lot of hypertech t-stats, but they're only like $20.

Any help?

Just go to Ford and get a motocraft one. I've had mine in for a couple years now and have had no issues with it whatsoever. My stock one (not sure if it was changed within the first 80,000 miles of its life) had at least 50,000 miles on it when the 180 went in. Buy something that is trusted (ie OEM)

So this will work without any modifications? [URL="http://catalog.oehq.com/item.wws?sku=12TP7D&mfr=ACDELCO%20US&weight=5&cookieID=1UG00XWSF1UG00YFCM&clientid=oehq]CLICKY[/URL]

ACDelco part # 12TP7D (All Makes-Thermostat-Prem Line) and 12S20 (All Makes-Thermostat Housing O-Ring)

Thanks for the help guys.

I have always had good luck with Motorcraft and Stant thermostats. Just make sure you get one with the little check ball like the stock ones have.

I have had a Stant 180* T-Stat in my Bird for going on 3 years now and it is still working like a champ.

Just remember that the hotter and engine runs closer to it's adiabatic efficiency, the more power it makes. If you install a 180 degree t-stat you'll notice a slight drop in fuel economy. Also unless you have a custom chip or reflashed EEC-V to turn the cooling fans on sooner, you are not completely benefiting from the cooler t-stat.

Then you can add more spark timing (hopefully) and increase power output.

I know that I need a chip (I'll just go for the xcal) for optimum performance, but should I just wait to get the t-stat until I get the chip?

I planned on chipping when I did a PI swap (whenever the F that will be). Would it be better to throw the t-stat in then or will I have any negative effects from the 180 that should make me stay with the 195 stock t-stat until then?

Well it depends on what you want to do. Regardless of what heads/motor you have it's not a bad idea to upgrade the cooling system. The cooler t-stat needs to work with the fan turned on sooner so the calibration has to be adjusted.

Take a recording of your fuel economy right now. Take a months worth at least. How many gallons to fill up, how many miles/mileage, etc. Then add just the 180 degree t-stat and check the economy again. I bet you'll see the economy has suffered slightly with no other changes.

To make the comparison fair (since it's not a controlled experiment), use the same gasoline grade from the same gas station and drive the vehicle the same.

As far as the EEC goes without the changes you won't be using the 180 t-stat to your advantage.
