Q: BOTTLED WATER IN COOLANT RESERVOIR
I recently poured about 0.5 Litre of bottled water into the coolant reservoir of my 2018 Elantra since the coolant level was below “LOW”. I’ve read that water can damage the system and cause it to rust. Should I add coolant on top to the FULL mark or should I drain the radiator first? Would 0.5 Litre of water and the rest coolant cause damage to my system? What is the best thing to do right now?? Plz help thx
