2013 Sonic LS - What hose is this?

[Parrot]

Hey all! I've got an issue with my 2013 Chevy Sonic LS. (When doesn't this car have an issue though tbh haha)

The car overheated while I was in a drive thru and before I could turn it off I heard a loud POP noise and then white smoke started coming from the driver's side of the engine. I checked to make sure it wasn't a head gasket issue and my oil is clear/there's no heavy smoke coming from the exhaust. I also checked the radiator, no cracks or issues.

I did just find a huge rip in one of my hoses though in the EXACT spot I am seeing the white smoke coming up. (I'm assuming it's coolant burning, since I can see some coolant pooled in little outside parts on the engine)

I want to be sure that this could be a viable cause of this issue and also I want to be sure I have the right hose for replacement. It's awful trying to get into the engine to this hose and my pliers won't fit for me to remove the clamps.

Could someone confirm or deny that this is the upper radiator hose? I put duct tape on there so it would be easier to see! Thanks!

That hose goes from the thermostat to the heater core.

Thanks! So just a heater hose then? Do you know what diameter the 2013 Chevy Sonic heater hoses are?

No clue. You’re best bet would be to take the hose off the car and have a auto parts store sell you heater hose by the foot.

That was my back up plan haha. Thanks for your help! Fingers crossed my car will be all good after this.

You need to figure out why it overheated. The way you describe it, the burst heater hose was a result of overheating, not the cause of overheating.
How many miles on the car? Maybe the water pump is shot and that caused a localized overheating. But, that is just a guess.
