Suspect the problem is the CPU...do you have and experience with this problem. The vehicle intermittently overheats.
Did you first check all fuses???? that be 1st !!!
dead cold engine, I OFF the rad cap, is the system full? of AF?
is the AF/ tested at 50% with the $2 tool? "prestone tool"
Does the AF coolant look like Mississippi mud?
AF= Antifreeze SOLUTION (coolant)
is this the 3.7L V6? , ????? that be first. what engine option. of 4.
even a 2.8L diesel.
no, the PCM is not the problem(CPU the brain) not at all.
unless the fans die... on 2.4L engine. got 2.4?
first tell us when it overheats. ?
parked. stopped only?
moving fast? ever? overheat.?
both ways?
Does the fan kick on , as the FSM tells you,.???
2 engines, have a viscous fan clutch others have electric fan
until you post engine. we can not help.
is the radiator fins clean? free of junk? front to rear.
if yes, it should not overheat moving fast.
if it only overheats parked, the fan is bad.
or clogged rad tubes... (easy test ask,with $15 pyro gun)
there is a start..

well first off depending on the year you could have up to four.now the easiest thing is to check trouble codes by turning yor key three times.now move it to the first position it moves to.thats were you need to end at all three times.now from that position you will move it quickly to the position when the accessories and idiot lites lite,right before it hits the starting position.so do that three times and wala if you got a problem with it your gonna know which one of the four you need to replace.follow the imortal saying of if it aint broke dont fix it ,oh ya to locate just look at other answer

any vehicle can have any component fail at anytime. The only way to know is to have it inspected for the correct diagnosis if your experiencing problems. If you want a second opinion because you don't trust the first one then your only going to get that at a repair shop.
