The fan clutch should have 4 or so bolts holding it on like most others. They are threaded normally, CW tighten/CCW loosen. So you would turn them CCW to loosen them if bolts are on the front and CW if bolted from the rear.
CW=clockwise
CCW=counter clockwise
Here is another easy way to remember... when facing the head of any right hand threaded bolt, or nut,,, Lefty Loosey,,,Righty Tighty
If the radiator fan won't work, it could be the clutch is bad. Radiator fans on the large V8's are supposed to "freewheel" if the engine is cold, and engage when the engine warms up. If the clutch isn't engaging, get a new one. It'a a simple replacment process, just pull the top half of the radiator fan shroud, pull the 4 bolts that hold the clutch to the water pump, then replace clutch.
The coolant enters the engine by way of the lower radiator hose and exits the engine by way of the upper radiator hose.
When standing in front of the van it is on the left hand side on the engine side of the radiator it's on the bottom. It plastic.
Standing in the front of the engine, It will be on the bottom right corner of the radiator. Towards the engine.
Standing in front of the vehicle looking at the engine, the crankshaft rotates clockwise.
Could be, Restricted air flow through outside of radiator, Restricted coolant flow through inside of radiator, Faulty fan clutch, Missing or broken radiator fan shroud, Faulty thermostat, Low on coolant,
Once the thermostat has opened, the hot coolant flows from the thermostat housing on the engine into the top of radiator and out the bottom of the radiator back into the water pump.
Follow the upper radiator hose from the radiator to the engine. The thermostat is located within the housing where the radiator hose connects tot he engine. Drain radiator, remove hose from thermostat housing, remove the bolts that fasten the housing to the engine and pull off housing, pull out thermostat noticing the direction it is pointing. Installation is reverse of removal (making sure thermostat is facing in the right direction). Refill radiator with 50/50 water/antifreeze solution.
a bad engine and transmission mount 1 in the rear near the fire wall or 1 in front near the radiator.
That means the engine is running HOT are overheating. Check engine coolant level, Thermostat may be BAD. Possible Fan clutch bad, Radiator stopped up. CHECK COOLING SYSTEM.
Everything depends on make and model, but usually, no you cant. A radiator fan is not designed to line up with the wrong parts. In some cases you may be able to fabricate one to fit. I fan clutch is driven by the engine. Electric clutch is controlled by the computer.
The way that is the easiest is to put an opened dish towel in front of the radiator. The engine must be running and at operating temperature. If the towel stays opened and against the radiator then the fan clutch is pulling sufficient air flow. If the car has air conditioning then the towel will be against the condenser.
