Q: Hello! I was running low on coolant so I added water until I could buy some.

asked by on September 02, 2017

Hello! I noticed I was running low on coolant yesterday morning so I added purified water until I could buy some more coolant later that afternoon. Now that I bought 50/50 coolant, can I add it on top of the water? I know I need to get it flushed but cannot do that until Tuesday so will using the 50/50 coolant on top of the remaining purified water keep my engine safe until Tuesday? Thank you!

My car has an automatic transmission.
