What happens if coolant is above max?
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.
The excess coolant is lost as it is dumped on the ground..
Does it matter if you overfill coolant?

What happens if you put too much coolant in the reservoir?
When the radiator coolant expands it will overflow into the reservoir tank. If the reservoir tank is too full, then it will overflow and spill onto the ground. Later when the radiator cools, the coolant will shrink some and suck the excess it passed to the tank back into the radiator.
How long can you drive with low coolant?

You can use clean tap water in an emergency, but antifreeze should be added as soon as possible.
Can too much coolant make your car overheat?

Is it normal for coolant to get low?
There are only two ways that the coolant in your car gets low. There is a leak, either in the radiator, the hoses, or the engine. The thermostat is set too high or there is a blockage, and the coolant is getting heated to boiling point, and the vapor is exiting the system, which reduces the coolant level.
Why is my coolant going low so fast?
Coolant loss may indicate a poorly maintained cooling system, a system fault, or even a change in driving patterns. For example, a coolant leak could have any of these causes: … A leak that only occurs under certain operating conditions. An undiagnosed cracked engine block or cylinder head, or a blown gasket.
Can you mix old and new coolant?

Should you ever need to top up coolant?
How regularly should you check your engine coolant? You need to check your engine coolant at least twice a year before summer and winter, ideally. Although, this advice may vary between car manufacturers. Coolant should be topped up whenever the level drops below the guide marks.
What happens if you don’t top up coolant?
Radiator Cap That Leaks The coolant can escape due to the overflow tube every time the coolant begins to heat. Since the radiator is a pressurized system, there may be a loss of pressure from the cap not fitting correctly. You can even experience coolant seeping out, if the cap is the incorrect for your car’s radiator.
How often do you need to add coolant?
You shouldn’t just add antifreeze into the radiator on a regular basis. You should change it out every 3–5 years or as recommended by your manufacturer. If you notice your antifreeze constantly getting low then you have a leak you need to address in addition to topping it off.
