Hey guys. I am in need of some mechanical suggestions. I feel like I've exhausted all of my options and have tried everything to no help. I have scoured all of the forums and have not found a fix. Here we go.

The general gist - My jeep overheats while in traffic or in idle. I have replaced countless parts and have had no success. If I gas my vehicle while in park or neutral and make my mechanical fan spin faster, it cools down to about 220. It has been 90 degrees and up and lately it has been in the 60s in NC, so I thought I had this issue resolved earlier in the week. Specs below.

Radiator replaced, including cap, less than a week old.

Coolant and oil tested, no trace of oil in coolant, no trace of coolant in oil.

Fan clutch replaced, less than a week old. My mechanical fan is intact and gyrates well.

Electric fan/ radiator fan replaced and turns on properly. (1 month ago)(a person who replaced a previous radiator for me when I worked 70+ hours a week did not secure it properly. It fell out of place while driving and was partially destroyed.) I replaced it within this month.

Thermostat replaced and tested, opens correctly, less than a month old.

Water pump replaced, less than a week old. The old one seems to have been functioning properly, but it is staying in the Jeep for good.

I have replaced the Crankshaft Position Sensor less than a week old(unrelated, cranking issues)

My fan shroud for my mechanical fan is intact.

I've checked the hoses for blockages and have found none.

I've lost so much coolant at this point, I can't even suspect "old coolant." Regardless, I flushed the radiator and motor through the thermostat opening.

My oil was changed less than a week ago to check for traces of coolant.

Once the thermostat opens and the electric fan turns on, I can FEEL coolant surging through my upper and lower radiator hoses.


***There are two key, possibly vital bits of information that I have deducted.
1. I did not have any overheating issues before my electric fan was replaced. The one that I had in the Jeep which was the original did not cause my engine to overheat. The original was much heavier. The new one provided by Advanced Autoparts is about 2-3 pounds lighter. The material in the original Jeep fan was a heavy plastic, almost resembling metal. The one I received is clearly lighter and is made of plastic(or whatever the hell they're made of) I experienced no substantial overheating issues before I replaced my electric fan which was then in pieces. HOWEVER, when my original electric fan was in place, it would run CONSTANTLY. At this point, I feel like a temporary fix would be to return my electric fan and pick one up from the junkyard. Thankfully, the electric fans are extremely easy to replace.


2. The ONLY hose that I saw something that might possibly be a clue, the heater core hose, when disconnected, discharged a dark fluid. This is my next course of action.

I've put so much money into this vehicle, and well. I don't even want to go there.

I need some feedback. I do not have another vehicle that I can drive and Charlotte traffic is horrible on my way back from work. Today I sat in traffic for far too long unable to do anything about my Jeep's temperature being high.

If I seem ungrateful or rude please forgive me. I am at the end of the line with these issues and could have purchased another vehicle with the funds I've used to "fix" this jeep.
Thank you for your time.
