'99 dodge intrepid 2.7 overheating issue

Howdy folks, my name is Arthur, Im new to the forum and not mechanically inclined, however I come here to seek help or tips on general stuff.

First off, I am having issues of my car overheating, on my 99 intrepid 2.7. I have replaced the water outlet housing, as I noticed calcium builduop around the edges and wher it was leaking to. For the past month I have been using water only, but..I finaly got the funds to get a friend to help me change it. The thermistat seems to be working fine, because we squeezed the hose and saw that water was being forced to the resevoir indincating that the thermistor was not closed. (not sure if that was an accurate way of testing). But, we also noticed that the radiator fan was NOT coming on, but the AC fan was coming on (while the AC was on , which is normal.) We did check the fuses , even added new ones, and still having the same issue. (radiator fan not turning on).

My question is , could the raditior fan not coming on, be a reason for the car to overheat, and could I get one from the junk yard. Also, I have tried, while the car was on to tap the fan, hoping itll kick it on. Could it be an electrical problem, if so, could I check the radiator fuse port to see if thers fire (with those fuse tester devices) .. Thnx for your help and sorry for the rambling..

PS. ther is no leaks, anymore, since I replaced the water outlet.

Thnx

See if a fuse is blown although I think if the engine fans are original a new set from the aftermarket wouldn't be a bad idea. Around $100 locally maybe a bit less online if you hunt around.

Need some clarification here! You talk about radiator fans and AC being separate entities.

I'm guessing you mean the Radiator fans turn on when you have your Air Conditioning on. Yet you don't see the same radiator fans turn on when your car is running without AC and is up to normal operating temperature and it's overheating?

There are two fans behind the radiator. DO both come on at the same time?

Ok, well ther are 2 fans behind the radiator, one on passeger and one on driver side, I am assuming the driver side is the AC fan, because it only kicks on when the AC is on. The passenger side fan, does NOT kick on , even when the car is getting hotter than normal. and NO, both do not ome on @ the same time. seems like just the driver side fan comes on when the AC is on.

Also, I have checked the fuses and they seem to be fine, as I have switched fuses around to the working fans to see if ther ok, and they are.

Yes, i replaced the water outlet, and we also, jacked the car up front, took cap off resevoir , and allowed the air to come out by watching the bubbling pop out.15-20 minutes later the car was starting to overheat, and water ws bubbling out after, and thats when we cut the engine.

PS. thanx for all the help fellas, I do appreciate it all.
