Wait until the engine is cold. Drain coolant. Remove the two bolts holding the thermostat housing. Remove housing. Pop out thermostat and O-ring. Install new thermostat, new O-ring, then reinstall the thermostat housing and tighten the 2 bolts to 11 ft-lb. Refill with coolant.

Default Draining coolant

Where is the coolant drain spigot and what is the best way to get to it?
Thanks

Default 11 Ft. Lbs

Use a torque wrench that measures in inch pounds. 132 In lbs = 11 Ft. lbs. Make sure to use a drop of Lock Tite BLUE. It lubricates the threads to assure more accurate torque readings and keeps the bolts tight. Bolt to thread friction is not torque. Bolt stretch is the desired function of applied torque to a bolt. If everything is not clean and friction free then the actual bolt stretch at a 132 In. lb reading will not be accurate. 11 Ft. lbs is not much. This is way more **** than what is required for a thermostat housing but it is how it is done properly.

I use that little spring loaded gizmo in my tackle box. What the heck, it's calibrated in lbs.

Ahh yes; the old Zebco De-Liar torque tool. My problem using it is always finding a wrench exactly a foot long so the scale is accurate.

Default Setting the PCM

After installing the 160* Stat, it IS necessary to reset the ECM correctly, or no difference will be noticed. The stock Stat is 192* which is significantly different. Once the ECM has been reset for 160, the fans will be set accordingly, and you'll run cooler. There are several other ways to complement the cooler running engine, but the 160* Stat, properly set-up, will make a difference.

BTW, the proper terminology is ECM, and it does NOT involve a full tune.

Make sure the tab on the gasket mates with the notch in the housing or it will leak. Trust me.

Wrong.
You will notice a reduced temp at cruise- about 180 degrees. In traffic, the temp will rise as with the oem stat before the fan kicks on but since you are starting from a lower temp, it will take longer.
A reset of the fan turn on temps will be required to keep the temp lower in heavy bumper to bumper traffic, however.

in the summer months your fans will run all the time with a 160...you must re-program/ if that helps.

I have Just a 160* in our '09 and '02. Work just as they should with No re-program. Not necessary. Cruise temp at 172-178*.
Fans work Exactly as before when engine heat goes up at idle.
