Hi guys how you doing? My problem is that my car keeps on overheating. I have changed the Coolant SNSR, Thermostat, upper & lower hoses and the heater core by pass hose to. The water pump works fine as I was told and radiator, and fan clutch works to because I have to put some little strength to move but I know something is not right....

Then Again When my car is turned off it reads hot between 150 & 160 and when I turn it on the first time of the day it will read cold and slowly rise again to hot....CAN SOMEONE HELP PLEASE!!!!!!

150 to 160 degrees? are you using the stock gauge because its not very accurate. and 160 degrees is not even fully warmed up yet. you might not even have a problem.

180-190 is normal temp.
I'd go to a auto zone or local auto parts chain and rent a radiator pressure test kit.

If your coolant system does'nt hold pressure,then you have a leak.

Before you do all that...Wait till the car is cold then remove the radiator cap and look at the gasket of the cap for rips or cracks in the rubber.

May wanna check the oil while your at it. Blown head gaskets will eat coolant and mix in the oil.
The pressure test will help pin point any leaks in the system using a 3ft. hose to your ear to hear it.

I think your system is fine though if its running at 160+ Maybe upgrade to the ford tauras electric fan, That fan does the trick.
Good luck bro & welcome to cafords [patriot]

The cap is new that I even struggle to take off at times. Pressure there is because my dad decided to take off the cap on radiator and it was like a volcano going off. There's no coolant either in the oil its nice and clean....So what you guys thinking? I'm honestly out of clues and don't know what to do other then change the radiator..what you guys think?

How hot does it get again? Is it puking coolant out the overflow tank? Are you running straight water? When its cold take off the cap and look inside the radiator while the car is running to see if coolant is flowing good; I seriously doubt its cloged. You may just have air in the system and need to bleed it. I use a vented radiator cap, and a thermostat with a burp hole installed with burp hole pointing up.

just making sure you still have that air diverter flap deal( the piece that hangs straight down and scrapes on all the curbs.) on the bottom of your bumper? ive seen a couple people come through with 5.0s that are missing those and they have similar problems

whats the temp that u think is overheating first?if it dont go over 170 to 190 u aint overheating.if it does, u said if flows like volcano ?is it after its been running for a while its again half way normal?just a quick check turn car off let cool down take off rad cap then crank if u got volcano u got blown head gasket.

I had the exact same issue with my old Fox, I did all the same stuff you did and it didn't get better. I ended up swapping out the radiator and it ran nice and cool. I've had luck finding radiators out at Pick N Pull, people have cars that overheat due to engine problems so they change the radiator. You can find the heavy duty 3 core ones. Check the T-birds, that's also a Fox platform car and the radiator is the same.

When your motor is at operating temperature, feel the corners of your radiator, if you find one corner cooler than the other (cold spots)chances are you have plugged cores.
