I was about to hook the heater up this after noon when I noticed the line coming from the firewall is crimped shut .. im guessing what ever I need to replace is behind the dash.. what do I need to replace exactly?

 

Heater core.

It's a big job.

Try to open the copper tube. Don't put to much force on it or you'll risk cracking the inner joint.

I have a heater core if you need.

 

yeah its crimped shut I just went to see if i could get anything in there to pry it back open but there isnt enough room.

how much you askin for the core?
