does anyone have any experience with this, is it easy? and is it worth the time and effort? and what exactly will it improve?
Thanks

I did this on My s-10. It makes your engine run a bit cooler thus giving a little better performance (less heat under the hood, etc.). You may need a chip with this to get the benifits from it.

I put 170 thermostat in my car (160 previously used on my 5.0 Mustang for years no problem) and half of bottle of Red Line Water Wetter-works great, especially in LA CA on June-September when 110 degree outside.

i think it's great. make sure of your minimum operating temp. if the thermo is below, the car will always think it's in warm up mode. on the zx2 the minimum is 170. i have a 180. pretty much same engine. i think it works great. good idea to install one if you have a udp too.

Order from Focus Central 170 deg thermostat $18 or so. Go to any shop to replace oil. They'll change you thermostat too (O rubber ring used again, no drain radiator). It takes extra 10 min and extra $10.

From what I understand..... all that a 170 deg thermostat does, is open to full flow once the coolant reached 170 degrees. However, our engines run super hot anyway.... so soon enough you'll be running @ 220 degreens and that 170 degree thermostat is as worthless as the stock one.

A thermostat does not keep your engine running cooler. So please don't think that it will.

My FlexLite 12" dual fans do the job!

Underhood temps are way down, even with no shield on my big as* log-style turbo mani.
