Must have blown a line on my way back to Ohio.


Does anyone know of any coolant lines back in this area? There is coolant on the sub frame and under the car.

Check the lines going to the heater core

Check the thermostat housing. It's made of cast aluminum and I've seen some completely disintegrate.

From a quick glance when i walked out during my lunch break it doesnt appear to be the heater lines. Topped off the recovery tank to monitor how much it goes down. Ill have to check the thermostat housing as well.

Thinking it could potentially be coming out of the a\c drain on the firewall

Changing the heater core in a Cobalt is a big job, pray that it's under the hood.

By the look of the fabric on the firewall I don't think I am going to be lucky with this one. Whole dash have to come out?
