No. The fan should shut off when the engine temp is to cold for the fan to be on. If its on all the time the temperature switch/sensor is probably defective.
No, there should not be pressure in the radiator after cooling down. If there is still pressure, it could indicate a problem with the radiator cap or the cooling system, such as a leak or a failing pressure release valve.
It can be very simple to remove the radiator from a Honda Civic. The first step is to drain the coolant from the radiator. The next step is to disconnect the cooling fan switch and remove the hoses. Then the cooling fan should be removed. Then the radiator should be unbolted and lifted carefully from the vehicle.
No

Cooling fan not working, or your cooling system needs a complete service. The cooling fan should be on continuously when the A/C is on.
You should replace the radiator cap if it is leaking coolant, not sealing properly, or showing signs of damage. A faulty radiator cap can lead to issues like overheating, coolant loss, or air entering the cooling system, which can cause damage to your engine. Regularly inspecting and replacing the radiator cap can help prevent these problems and maintain the efficiency of your cooling system.
If you take the grill off of the front of the vehicle you should be able to see the radiator. Look on the passenger side of the radiator, your wing nut type plug should be on the side of the radiator. The Jeep Cherokee radiator drain plug is plastic and very fragile. You should remove the lower radiator hose to drain the cooling system.
By fans, I assume it has more than one. One of these fans will run continuously when the A/C is on. The other fan should only run when needed to cool the engine down. In stop and go city driving in the summer with the A/C on, both fans may very well run continuously. At highway speeds, only the A/C fan should normally run. Sounds like you need to have your cooling system serviced. A complete drain and flush of the cooling system and a replacement of the thermostat may help. Also make sure the radiator external fins are clean and not clogged with bugs and debris.
The cooling system bleed valve, on your General Motors 5.7 liter engine, is located on the bottom of the radiator. The bleed valve should be in the middle of the radiator bottom.
Entire cooling system should be flushed to remove dirt, scale, rust and sediment buildup which will corrode and clog/ruin your engine/cooling system
It should be where the top radiator hose connects to the motor. Take the hose off and the thermostat housing should be held on with two bolts.
That one should run anytime the a/c is turned on.
