Thermostat change

I accidentally posted in general forum figured I would re post here since this is a JK topic. Anyone out there running a 180 degree t-stat, if so for how long and with results? After talking to RIPP they have tested them and recommend the swap. One of their guys told me that it was standard for them to change JK t-stat from stock to 180. I am thinking about making the change just wondering if any of you have ran the 180 t-stat for a few miles and with what results. Also anyone getting a P0128 in cold weather for not warming up fast enough?

Not sure about this. I haven't done a t-stat change yet.
Post this question in this thread (RIPP SC-only thread) and see what answers you get: http://www.jeepforum.com/forum/f96/r...-only-1513250/

TO meet emissions and get the mileage we do get, don't lower you engine's temp. It's designed to run where it is.

A 180 thermostat will lower the engine temp on the highway as there is plenty of air flowing through the radiator. Under-hood temps are not high on the highway.
The 180 thermostat won't lower the engine temp when going slow unless you also lower the "fan on" and "fan off" settings.

If your goal is strictly lowering the under-hood temps, consider something that will aggressively do that while letting the engine run at its design temperature of 195.

YUP, do like rj says--

Don't try to apply 1960 engine op/performance temps to the new jeeps/cars, it's ridiculous, but thats the way they're designed now/w hi-temp gaskets/fitting/components/plastic-etc-

You might wanna get a scooped/vented hood and don't put too much crap in front of the grill slots-

Most of what you do for temp reduction will be for YOUR personal pleasure and not affect the engine/compt-ops

My '08 JKUR has operated in the NorNv desert, at 90 to 115F for over 5 years and with some required maintenance--she ops fine, no degradation-

Good luck

JIMBO
