What thermostat should i use with my 4.6L Stroker

[jeeptj01]

I am running a 4.6L Stroker in my 2001 jeep wrangler and i was wondering should i be running the stock 195 thermostat? I guess the reason why im asking is because when ever i use my a/c my jeep gets too hot to the point where i have to let it cool in order to start it. It only happens when its really hot out or i use my a/c. Should i try a 180 thermostat?

Run the 195, if you run a colder one the computer will never change to closed loop, something else is wrong, fan clutch?, radiator plugged?, crappy water pump?, is the shroud still on it?

I am running a 180 with my stroker. It's been very hot down here in the southeast (101 yesterday), and I don't have any problems with overheating while running my a/c. The hottest its ever got was about 205 in stop and go slow traffic (in this hot 95+ temp). Also no problems in the winter time warming up to get the computer in closed loop.
Still, look for other problems. Your jeep shouldn't overheat even with a 195 thermostat.

Flush the whole cooling system, install new hoses, and refill the system with fresh coolant. There's a good chance that your radiator is clogged up with crud.

look in between the rad and condenser as well, lots of buildup likes to stay in there. when i worked in the a/c shop, we would see cars with solid bugs and dirt in between the two alot.

I ran the 180, in mine for a while, until winter came in the mountains and the wife was complaining about no heat:( So the 195 went back in, it never overheats in the summer a/c on. But I also put the big 3-core brass radiator in it when I did the engine.
