There should be a petcock on the bottom of the radiator. If not, remove the lower hose, and this will drain the coolant. You may not need to drain it, as I usually don't when I do them. You will lose a little out of the hoses, but it is up to you.

open your skylight and feel in the front corners for muck stuck infront of the drainage holes. Use a pipe cleaner or other wire to poke through the holes and the water should drain out. It is a little difficult to see the holes but just feel around.
Park the Nissan Altima on a flat surface and set the parking brake. Next, open the hood and check the external temperature of the radiator. If the radiator is warm to the touch, wait for the radiator to cool before you continue.
Twist the radiator cap one turn to relieve any pressure. Step back from the radiator and allow a few seconds to pass, and then completely remove the radiator cap.
Place a bucket or tray with at least a 2-gallon capacity underneath the radiator and below the drain plug. The drain plug on a Nissan Altima is on the passenger side bottom of the radiator.
Loosen the drain plug and let the old coolant drain completely into the bucket. Take care while loosening the drain plug, because it's plastic and can be brittle. Pour the old coolant into a sealable container for proper disposal later and put the bucket back under the drain plug opening.
Close the drain plug and pour distilled water into the radiator until it's full. Then, open the drain plug and let the water flow into the bucket. Keep repeating this procedure until the water runs clear and debris free into the bucket. You will need at least 3 gallons of distilled water.
Make sure to tighten the drain plug and fill the radiator with fresh coolant. Refill the radiator to within an inch of it overflowing. Check the drain plug and hoses for any possible leaks.
Start the Nissan Altima and turn the heater to the high setting. Let it run for about 10 minutes and shut the engine off. Check the coolant level and refill, if necessary. Finally, put the radiator cap on and close the hood.
I have the same problem on my 2004 Nissan quest, and the battery will die if i do not drive it for 3-4 days, i have replace a ACdelco ACD24F60 new battery and it has the same problem too.
I just get a Nascar advantage charger Model 11-1577-6 from Canadian tire, and try to recharge it but the LED flash after few hour, I set to normal battery type, any idea how to fix this problem.
You really won't lose that much coolant in just changing the upper hose. But, crawl underneath the front of the car, and somewhere along the bottom left or right hand corner of the radiator, you'll find a valve of some type. Either rotate/turn the valve, or pull and turn, to open. Be sure to have a clean bucket ready and under the drain while doing this, to catch the drained fluid.
Then remove the radiator cap to allow air in the top of the radiator and speed the flow. Drain only to a point in the radiator that is below the lowest point of the top radiator hose, probably the engine end. Close the drain. Remove/replace the radiator hose. Pour coolant from bucket back into the radiator where the cap was removed. If it does not all go, then save. Start engine and allow to warm up. As soon as you see the level drop (meaning the thermostat has opened) add more coolant, and continue doing so until no more coolant can be added. Replace the cap. Monitor the coolant reservoir and add coolant as needed to the appropriate fill line. Do not store excess coolant where pets/animals could consume as it lethal such creatures.
Make sure the engine is cold before you change the coolant.
Open the hood, place a container under the radiator, and look for the drain-plug under the radiator. Remove it by turning it counterclockwise. Remove the radiator cap. Once coolant drained out, replace the drain-plug, and put in fresh coolant. You might also remove the coolant reservior and empty it.
