Thermostat - 195 or 180?

<font color=blue>What are the pros/cons when purchasing a thermostat? what temp do I want?

I'm replacing the water pump at the same time I'm replacing the thermostat... what else do I need to think about?

I remember a trick, but don't remember it's purpose: drill a small hole in the thermostat... but where???

Thanks! (someday, I'll run a search instead of resposting...) [img]/wwwthreads_images/icons/wink.gif[/img]

Re: Thermostat - 195 or 180?

With a computer controlled vehecle, you want to run the OEM specified temperture, ussually 195 dgrees. Running a colder thermostat can make the engine run rich. Some aftermarket chips specify a 180 degree thermostat, but they are calibrated for that.

Thanks, Ray

Re: Thermostat - 195 or 180?

running the spec'd t-stat is true to a point, that is the normal temp for it to open, you did not specify whether you live in an un usually cold or hot climate or how hard you work you jeep, (like does it spend a lot of time idling in traffic or most of the time cruising @ highway speeds?) As Far as drilling a small hole in the stat itself, it's only real benefit may be to help prge the air from the cylinder head during re filling so as to avoid air pockets and hot spots, it also could allow it to warm up slightly slower than normal and maybe more uniformly, but i don't see that a hole that is very small could have too much of an adverse affect overall, especially since there are certain ones that come with the hole pre drilled.

If you live in the desert as IIdo, 160 in the summer and a 180 in the winter,I've been doing that for three years now with my Jeeps and I have no problems. The cooler the better.
