I drained the radiator to put in fresh water water came out black
The car is also leaking out water .The car doesnt leak water when running parked, but it heats up when I take it to work so I carry an extra gallon of water. I recently bought this car it was repo. I hope its not something to expensive to fix and is it fixable.
Re: I drained the radiator to put in fresh water water...
You should be using Antifreeze in the coolant system cause it boils at a higher temperature and will not evaporate.plus rest protection and lubrication for the water pump. Water will rust the water jackets inside the engine and ruin the cylinder head gaskets .I suspect the leak is either a simple fix like a hose or water pump seal a big fix like a cylinder head gasket. Water can cause all of these problems.

check for leaks, put fresh water/coolant into the radiator and overflow bottle after the engine and radiator has cooled so you don't get burned. hopefully the car will restart. remember that you can cool a car that is starting to overheat by running the heater in a pinch. It's not a fix, but an emergency measure.
Does the leak show up on the ground when you are parked with the engine running or stopped. Determine where it's leaking from. Hose? near fire wall, near radiator. Water pump will leak when it's worn. Can you smell it when you're inside the car? heater core.
If your water ports are in the Intake manifold, it would be possible to crack the casting with a mounting stud. If you were to remove the mounting studs for the throttle body there is a chance the stud would show staining from the Antifreeze.
You need to pressure test the cooling system with a Radiator pump. You may be able to get a loaner from Autozone or Oreillys by leaving a deposit. When the Radiator is pressurized on a warm engine. the thermostat will be partially open and the Intake water jackets should pressurize too! There can be pressurization from the lower Radiator return hose on a Cold engine test as it is a closed system, but you could have an air pocket in the Intake. The air would have to bleed out before you had flowing Antifreeze.
In either the Warm or Cold test of your Radiator, the Pressure would drop in the gauge as you have a hole in the system. You should also be able to tell by looking at the sparkplugs to see what it is they are burning.
You may be able to stop the leak with a good leak sealer. If the leak is in the Intake, the induction system is evenly(?) spreading the Antifreeze to all 8 cylinders and the valves are keeping high pressure away. It is not a combustion chamber leak.
The more modern stop leak products can cost about $16. You add this product, run the engine, then drain the Radiator and put in fresh Antifreeze. Its that potent. Or you can go to a Salvage yard and get another Intake manifold. I hope you have found my solution helpful.
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.
Check you to see that you don't have loose or leaking cooling hoses, a bad radiator cap, a loose radiator drain plug, or a failing water pump.
If all these are OK, put a bottle of BAR's radiator stop in the radiator and run the engine in idle for 15 to 30 minutes. Available at your local auto parts store.
If your leak is not to serious, this should fix the problem. Put a bottle of radiator stop leak in your cooling system and repeat the procedure once every six months, to lubricate the water pump and keep leaks sealed.
the fluid may be goind out the exhaust, look foe excessive moisture out of the tail pipe, if you gotta fill it so often then its going somewhere right? may be sign of a bad head gasket, jut one more thought, are you using anti freeze or just plain water, water evaps quick, and a bad cap will let pressure escape and evaporate quickly, so you will not see a leak, good luck
This is how I like to do it. Make sure the car is parked with the front end at an upward angle. Drain the coolant from the petcock at the bottom of the radiator. Remove the upper and lower hoses at the radiator. Remove the thermostat housing, and the heater core hoses at the fire wall. Flush out the radiator by pouring fresh water into the overflow, and the hole where the thermostat was. Flush the heater core as best you can by pouring fresh water into the heater core hose connections. Let all the water drain out, then button everything back up and replace the thermostat with a new one. Refill the rad and engine by filling the coolant reservoir with a mix of 50% water and 50% antifreeze, or buy the premixed stuff from the auto parts store. (Buy 4 jugs of premix or 2 of straight antifreeze) Run the engine until it reaches operating temperature and the upper rad hose gets hot. Rev the engine a little to help get the air out of the cooling system. When the thermostat opens, the coolant level will drop in the reservoir, so top it up and replace the cap. Check for leaks, and check the coolant level for the next few days, and check for leaks. Dispose of the old coolant responsibly
there is only one thing that leaks water there, that is the AC condensation drain, water forms as part of the AC cooling the evaporator core, this water must be drained away or it will flood onto passenger area, so there is a drain on the passenger side at bottom of firewall, will leak allot of water depending on how humid the air is.
the black chunks could possibly be from someone putting a stop leak solution into the radiator first drain the coolant system fill up with clean water put in some Prestone 10 minute flush and then drain and put in a flush tee in the heater hose not the one going to the water pump but the one going to the engine block open up the drain hose and run water through until clear and refill with new antifreeze and make sure car runs until all air bubbles are out and then replace the cap
