The coolant has to be escaping from the system some place. Coolant does not just disappear. It could be escaping thru the tail pipe as white smoke while the engine is under a load. Radiator cap could be letting it seep out as steam also, but I would imagine you would see or smell this if it were the case. Front passenger floor I'm assuming is not wet and coolant is leaking from the heater core assembly? Has the system been pressure tested with a coolant pressure tester and watched to see how long the pressure stays up?? (engine cold of course)

When i leave my grand vitara on idle it pumps all coolant out of the rad into over flow bottle

Is your cooling fan coming on? Make sure that it is. If not check fuses, relay and fan. The fan should come on and draw air through the radiator to cool the coolant if this isn't happening then the vehicle will overheat and as the coolant expands in an effort to relief the pressure the valve on the radiator cap will allow coolant to exit the radiator and go into the reservoir. This would be a good time to service your thermostat and change the radiator cap

engine running too hot.check coolant level, should be 50/50 antifreeze and water.replace thermostat and radiator pressure cap.check antifreeze level in the radiator,coolant level should be just below radiator cap, add coolant to overflow jug,should alway be at the full cold mark.empty coolant overflow jug will allow air be drawed in the coolant system causing overheating.if overheating happens when coming to a long stop.could have faulty engine coolant temperature sensor or bad coolant fan fuse or relay.

The fan on the radiator doesn't always come on, and there is a slow leak of water coming from the fan. What do you think is the problem?

Chances are that the radiator behind the fan has a leak (fan has no water supply so can't leak water). Have the system pressure tested to find the leak. As far as the fan not coming on, it is also likely that the sensor that controls it is sometimes deprived of coolant and therefore not reading properly (because of radiator leaking)
Therefore, have the radiator checked, repaired or replaced, then, if the fan still mis-behaves change the coolant sensor, check fan relay and connections. If water got into the fan motor, it may have caused a problem but the motor is supposed to be sealed and that's doubtful.

My 1999 jeep gcl ac line burst and now my radiator fan does not work. Do i need to replace the fan relay or might it be just the fuse?

you should always check the fuse's first, that is a starting point. The coolant fan relays are common to go out in the vehicle.

Dodge Caravan is notorious for failure of the electronic cooling fan control module (AKA cooling fan relay). This is not a "relay", it is a solid-state control unit, but many people call it a relay anyway.
It is mounted on the inside of the left frame rail just behind the radiator. You have to look up from UNDER the vehicle to see it. It looks like the picture below. The picture shown is very close to actual size.
