Overheating,can't find thermostat

Knowing Chrysler,the thermostat housing is probably right at the top of the engine.You should see a little pressure relief valve,underneath which lies the thermostat.With the car cooled completely off,unbolt the
thermostat housing,pop it out,slap a new one in it(replace the gasket too)and bolt it back.Go out and drive it around for a few minutes and get the engine warmed up.Turn off the car,open the hood,lay a towel or something on the engine in front of the thermostat housing,take a small wrench and slowly open the pressure relief valve.At first it should sputter as air escapes from the coolant system,eventually you should get a good flow of coolant,close the valve. Make sure to keep your coolant overflow at the proper level because if it drops too far it will **** air into the cooling system and while you are driving along it will think that the system is overheating and blow the pressure relief valve.Make sure it
is right side up when you put the new thermostat in.
