noticed that the fan on the radiator is lose not the whole assembly just the blade and it doesn’t turn on I checked the fuses they all look good so I’m assuming its the wireing or the actual fan just needs to be replace anyone now if I can remove. the can and connect it To alternate power source to test it? thanks in advanced for any input

To see if it’s the actual fan motor, you can disconnect the connector to the fan and jump a couple of wires to the battery to see if it turns on. If they turn on then most likely your fan motor is bad. Check the relay as well. It could also be your thermoswitch isn’t working properly as it might not be reading the proper coolant temperature, preventing the fan from coming on.
Watch this from 9:00-16:00.
First try to spin the fan by hand and see if it spins freely. If it binds up or doesn’t spin freely, then there’s a high chance the motor is done for.
To test the fan, it should be a single speed fan with 2 wires. One is ground and the other is power. The black wire should be the ground and the other wire would be for 12v. Ground the ground to a good body ground or the ground side of the battery and then hook up a wire to the positive post and touch it to the other terminal. The fan should immediately start to spin if you have it hooked up correctly. You can try to turn the fan by hand and see if it will turn by itself with power hooked up to it ( but be careful, obviously a spinning fan can hurt your finger! )
If the fan fails the test, then it’s time for a new fan. If the fan works, then you will want to find the fan relay so that you can jump it and see if the fan turns on. If it doesn’t, then you will want to test for 12v at the plug for the fan.
If the fan works by jumping the relay, then the temperature sensor is likely the bad component.
You can hook 12v from the battery to the fan connector unplugged.
If the car has a working ac.You can turn it on and the fan should

I checked the fan it’s lose and wobbly it even touches the radiator I am assuming that the motor is bad but wil still attempt to see if I can start it up ty
