Hi there. If the engine continues to burn coolant then you may have a warped block or there are a few other places where coolant can enter the engine. I have seen cracks in the timing cover and in the intake manifold that can cause this. I usually need to pressurize the cooling system and use a camera to check these areas to find the leak. Some of the time I must also use dye in order to find it. If you need some help with this, consider using YourMechanic, as a certified mechanic can come to you to [diagnose where the coolant is being lost] https://www.yourmechanic.com/services/coolant-is-leaking-inspection

Coolant that is trying to travel over an overheating engine can end up burning up on the block as the temperatures from both sides collide into generating even more heat.
Coolant can also burn internally if it is leaking into the combustion process. Heavy white vapor from the tailpipe indicates you may have a bad head gasket, and if you see this you should stop driving the vehicle and get it to the shop immediately before further damage occurs.
Providing that the engine is running well, with no leakages or damage, you can expect a coolant loss of 0.25% every four to six months. This means a loss of two to three ounces a year is completely normal.
Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant. Dirt or oil in your coolant can accelerate wear in your system, leading to leaks in your water pumps, at gaskets, or at o-rings. Flushing your cooling system is the best way to stop this type of leak.
If the coolant level is dropping and there is no external leak evident, then the coolant is probably leaking internally, into the engine. If the car has recently overheated then this could have caused the head gasket to fail. If it has, it could be leaking coolant into the combustion chambers.
One way to tell is by looking at the color of the smoke coming from the vehicle`s exhaust pipe. If the smoke is white, it`s probably just water vapor and not coolant. But if the smoke is blue or black, that`s a good indication that your car is burning coolant.
Thick white exhaust smoke indicates a coolant leak, which could cause overheating and put your engine at serious risk of damage.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Yes, engine coolant does go bad. Older fluid may cause acid buildup, may become contaminated by rust or scaling, and may have reduced resistance to boiling and freezing. Deteriorated coolant/antifreeze may cause your engine to run hotter than normal or keep the engine from starting in colder temperatures.
Too much coolant will not cause overheating. But if the ratio of antifreeze is above optimal then the engine will overheat.
Oftentimes when the thermostat fails, it remains in its closed position. As the engine overheats, coolant will overflow out of the thermostat housing. This means that coolant leaking out of your engine could be a sign that your thermostat has gone bad.
Leaking Coolant – If you see white smoke under the hood, it`s most likely burning coolant that has come into contact with the hot components beneath your hood. This smoke will smell sweet.
Fresh antifreeze is a clear brightly coloured liquid, usually blue, red, green, violet, yellow or orange but this will vary depending on the manufacturer`s formulation. Over time, your coolant will become dirty losing its colour and becoming darker, often an oxidized shade of brown.
What colour do you need? Green coolant is the conventional coolant (Ethylene Glycol base) and is the most popularly used coolant. Red coolant typically has a base of Organic Acid Technology which is designed to be more suitable for aluminium radiators.
If you don`t have coolant available, you should top up your radiator with the highest quality water that you have. Ideally, this would be distilled water. You can also use bottled water or tap water.
Whining or Groaning Noise
A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen. Pulleys have been known to fail due to rust, which can cause cracking between their bolt holes.
When a water pump completely fails, it is no longer able to move coolant through the engine; this causes it to overheat. If you see steam, pull over immediately and call your mechanic for assistance — continuing to drive with an overheated engine can damage it to the point that it will need to be completely replaced.
If your coolant reservoir is boiling but your engine doesn`t overheat, then your coolant may not actually be too hot. Those bubbles you noticed are more likely air bubbles that found their way into the coolant reservoir—not from the piping hot coolant. In most cases, the issue is actually a leak in the radiator cap.
If the radiator cap is stuck, fluid cannot get released. This will cause pressure to build inside of the radiator, causing the hose to leak or break open. If you notice coolant near the radiator or the radiator cap, then you clearly have leaky coolant.
Older vehicles are known for overheating because they`ve got old cooling system parts and some cooling systems and vehicle engines are not designed for today`s driving.
The maximum level is below the top of the tank. That allows for possible expansion of the coolant in the system. If you fill it beyond the maximum level, probably at some point the excess overflows out the overflow tube of the reservoir as the coolant from the radiator expands into the reservoir.
If the temperature gauge consistently shows the engine is warmer than normal, have your cooling system checked ASAP. There are many possible reasons that your engine is running hot, including low coolant levels, a clogged or closed thermostat, a failed head gasket or a water pump malfunction.
