Well my heater core went out on me the other day, damn thing blew coolant all over the inside of my csr. Anyways I change the core out for a new one.. Added new coolant and the damn thing still wont blow hot air?? any one know what else could be wrong?

 

you could have hooked it back up improperly, not pluged somethin in, etc.

 

well after we hooked it back up it started to blow hot air.. then it got cold again?

 

did you refill it with coolant?

 

Make sure you've got enough coolant, and leave the heat cranked all the way while you fill, and while you drive so it can work out any air trapped in they system. Do you have a bleeder screw on the coolant line where it runs into the head at the front, try cracking that to release any air if you do.

Yeah, sounds like there's not enough coolant flowign through there, make sure the car's warmed up and full of coolant, and leave the rad cap off so air can get out of the system.

 

already did all that. I let it run for about a half hour, It had heat during this time. I took it out for a drive and about ten mins into the drive it lost heat again??
