Heater Core Leak
I have a 2007 Suburban 1500 LS.
I believe I have a leak where the coolant lines go in through the firewall to the heater corer. I can see a drip from the out-board (right side of the vehicle) line.
Before I get in to trying to remove and replace it, does anyone know of a good video showing how to do it? Any tricks I should know about?
