170 Thermostat ?
I'm going to flush my radiator this weekend and change out the thermostat while I'm at it, I was wondering if putting in a 170 therm on a stock 3.4 would have any added benefit over a 180 therm? I searched thru the threads and all I could find was engines that have the SC and or URD. Any feedback is appreciated!

Will it give any performance such as better mpg, more hp assuming that the engine will be running cooler? Are there any drawbacks to using a cooler therm on a stock engine as opposed to using the 180 therm?

you want to make sure that your engine does warm up to 'operating temps' it burns gas more efficently that way, and helps keep the oil the right consistency, but I would think that 170 is as good as 180, my thinking is that it may not help a lot, but I dont really see that it can hurt.

Here is a good article on the benefits and drawbacks of using different temp thermostats. http://www.carnut.com/ramblin/cool3.html Looks like 180 is a good combination between power and engine wear.....
I think the reason a 170 is used at all is to help combat localized hot spots and the dreaded "pinging" that can be induced by supercharging and higher cylinder pressures/intake charge temperatures.

A bottle of Redline's Waterwetter does actually help maintain a little cooler head temp. I ran a bottle of this and a 10/90 mixture of coolant/water in my Eclipse in during summer race season.

By the way not to digress from the topic, does anyone recommend a brand of flush or should I just stick with water?

Check out this thread for all the coolant info (warning, possible info overload):
