I have a 08 5spd Aveo with AC. I had a cut on my top coolant

Customer Question

hi i have a 08 5spd Aveo with AC. I had a cut on my top coolant hose and replaced it. The coolant ran dry before I could get somewhere and let it cool down. Upon inspection the next morning I found the cut and replaced the hose. I only refilled the system with water. Should I flush it and refill it with 50/50 coolant? An how can I tell if running the coolant dry damaged my engine?

Hello, what are your outside temps where you are? did engine overheat and if so, how long , how high? is engine running smooth?

Central Kansas has been in the 80-90s the last two weeks. It did over heat, with the temp gauge pegged at High and steam was coming out under the hood. It was night and I pulled off the highway and looked at the engine but couldn't see anything. I only had 6 miles to go so I turned on the heater on high and drove slowly to my destination, maybe 10-15 min. Everything sounds ok to me, no pinging or knocking. but I am no export.

well, hard to say, I doubt engine damage per your description, Todays engines can take a good bit, Filed with water, runs ok, no smoke, runs smooth is a VERY good indicator engine is likley just fine, Missing? then possible headgasket blew when overheated.So, 2 choices. you can leave plain water in it as long as temps outside remain high, Coolant does help cool a bit, hard to explain better than water so, for short term? water is 100% fine especially as you are driving to see if any engine issues, Which I doubt, Once confirmed engine is ok? I highly recommend getting coolant in the engine, NOT just water, Coolant also aids in preventing corrosion, rust and so on, water does not. water is short term only

ok to wait on the flush for a week?

absolutely. NO harm done and do suggest doing that, Wait and be sure all is ok, just keep in mind coolant does a little more than just keep from freezing, Hope this makes sense
