Furthermore, can you top up the coolant with water?
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.
Similarly, can I use water instead of coolant in an emergency? Generally speaking, water isn't good for your radiator or engine and should only be used in emergencies. This is until you can find and add the correct coolant. So now you know what coolant/antifreeze is, why it's vital to your vehicle, and how it helps your engine last much longer.
Herein, can you just top off coolant?
Topping off coolant ignores the root cause of the problem. Fluid will continue to leak, meaning you'll have to continue to top off the coolant to stay ahead of the leak. Leaking coolant leaves you at a higher risk for an overheating engine.
Can you drive with low coolant?
Driving with low engine coolant is never a good thing to do. It can create air bubbles in the system, which in the worst case can damage your engine seriously.
