thats pretty much all you do...just make sure you clean the area where the thermostat connects and make sure you use a new gasket or clean the old one goodHow do you change a thermostat on a 2000 Jeep Cherokee?
i owned cherokee for 10 years %26amp; due to engine switched thermostat TWICE EVERY YEAR - crazy, but true %26amp; ran better.. reason was so ran better in cold %26amp; then hot weather. Soooooo, from all that I can tell you problems I had. First the dude who mentioned about air is smoking crackk. Also I found that gaskets are more problem than they are worth. Just use very good high temp tube of gasket gunk - yaknow the stuff you squeeze from tube and spread like frosting. Now make sure you let that stuff dry way longer than recommended, like 12- 24 hours would be good ( better safe than sorry). To help keep the coolant away from area where you are trying to seal I advise take apart first then when going to install jack up front to make coolant flow back away from thermostat. Also could just soak up with towel until area is dry. Now here is biggest problem - so very very easy to over tighten %26amp; break metal (cast aluminum) housing or under tighten %26amp; leaks. Check for torque recommendation (library or parts store if you dont know) %26amp; slowly do each bolt as close to same time as possible (i.e. one turn on one bolt then one turn on other). Whatever the torque setting is do NOT go even one pound past that. better to be a couple below than over. You can usually rent or borrow torque wrenches at parts store. I also decided to just buy extra housing for a few bucks just in case %26amp; that way always had extra. Dont forget once ready to start er up, refill coolant, start engine, run heater for few seconds %26amp; cycle it on %26amp; off, then shut off engine %26amp; check level but make sure either engine cool or checking at coolant resevoir tank (the plastic clear one). Personally I just leave radiator cap off 1st time and not let engine get hot, but only do that if you know what you are doing as not exactly safest way. ummm, little tidbits, bolts are not easy to get to, coolant is poisonous to animals, i have yet to ever overtighten belt but easy to not get tight enough which means battery wont charge good %26amp; can ruin it, make sure metal surfaces are very clean before assembly, not bad idea to test new thermostat in hot water to make sure it moves at right temp (rare to be bad, but sucks if it is), and lastly good luck
You will also need to bleed out the air that will be trapped in the cooling system or the vehicle will not work correctly..
