Is it OK to add new coolant without draining the old?

What are the signs of low coolant?

Warning signs of low or no coolant/antifreeze: Rising temperature gauge: A rising temperature gauge may be due to an increase in your engine’s temperature. Automatic engine cut-off: Most modern cars are equipped with an automatic engine cut-off feature. When coolant is low, your engine will start to heat up.

Can I just add coolant to my car?

Loosen the reservoir cap just a little, then step back while the pressure releases. Then, remove the cap completely. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water.
