How To Top Off Coolant
With the radiator cap off, run the engine until the coolant in the radiator is warm. Top up until the level remains constant. Refit the radiator cap. Spread some newspapers on the ground and park the car with the engine and radiator over them, to isolate any leaks.
Can I just top off coolant?
If you can't see any coolant in the radiator and it has a cap that you can access, go ahead and top it off until you see coolant at the bottom of the neck. If air is trapped inside, it could rise to the surface, causing the level to drop. In that case, just fill it up again and put the cap back on.
Can you top up engine coolant yourself?
Only refill your engine coolant when the engine is cold. You can buy pre-mixed engine coolant or mix it yourself with distilled water. Most brands recommend a 50/50 mix, though some suggest a blend of 70% coolant and 30% distilled water – especially for use in cold weather.
Can you pour water in engine coolant?
While it's ideal to add a 50/50 mix of coolant and water (or a pre-mixed coolant), if you absolutely have to keep driving, you can add water to the radiator to get you to your destination. If you attempt to remove the cap while it is still hot, hot coolant can sputter and may cause burns.

You can add the coolant without flushing out the old. However, with time, the older coolant becomes acidic. This can cause corrosion, and afterward, can cause defects in the cooling system. Its recommended by most manufacturers that you replace the coolant after every 30,000 miles.
So, you might ask how much coolant does my car need when empty? Your coolant reservoir tank should be at least 30% full. Most reservoir tank has min and max mark drawn on the side of the container. The most common cause of a coolant leak is a bad radiator cap, bad radiator fans, and loose radiator hose clamps.
Q: Is it normal for the coolant level to drop? Yes, due to the extreme engine temperature, the water element within the Coolant tends to evaporate, resulting in a coolant level drop.
If your car has a low coolant you can drive for some time. It really relies on the level of coolant. If it is low but it is above the minimum, you can drive your car for a few days. But if it is below the minimum, please do not even try to run your engine.
your coolant level is low
solution: this is potentially an easy fix. simply top up your coolant to the “max” or “full” level when the engine is cold. use a 50/50 coolant-and-water mix, as specified in your owner's manual.
If you coolant isn't circulating through your engine correctly it will begin to overheat. Even if you don't have a leak over time coolant can evaporate or get clogged with particles causing it to circulate incorrectly. The hoses that circulate your coolant can become eroded, clogged, or detached over time.
If your coolant level is too low (below or near the lower mark), top it up using a 50/50 mixture of water and antifreeze (for normal driving conditions), or pour pre-mixed antifreeze straight into the reservoir. You can use clean tap water in an emergency, but antifreeze should be added as soon as possible.
A typical automobile cooling and heating system can hold up to 3 gallons of antifreeze. Different systems require different solutions to be added to the water. Antifreeze, as well as rust and mineral inhibitors, are common additives.
If the coolant level is low in the reservoir, you can refill it to the max fill line but do not overfill it. The coolant mixture expands when it heats up and needs the extra room. Keeping your coolant at the correct level is one of the ways to keep your radiator good working order.
Your radiator cap helps control pressure within your cooling system by redirecting some of your coolant into an overflow tank. If the cap goes bad or develops issues, it can release too much coolant too quickly, leading to an overflowing reservoir and mysteriously disappearing engine coolant.
