How much should I torque down the thermostat housing and A/C compressor to bracket bolts? Also, what are the advantages/disadvantages to using a 180* thermostat instead of the 192*? Thanks
A 180 degree thermostat will open at 180 degrees, instead of 192. This allows your engine to run cooler. This is a smart play for our mustangs, which are known to have issues pinging at high temps.
I "hand tighten" the t-stat housing. Carefully. I do this because I reefed them down one time and put a steel bolt right through it. If you break it, you can get a new beefier one at NAPA for like 9 bucks.
180* is your best bet thats what i run and the thermostat housing bolts are torqued to 71-91 inch lbs. 0r 6 to 9 foot lbs. A/C compressor to bracket bolts 22-30 ft lbs.
