Welcome to the forum from Oregon.

Care to share the vehicle/truck info? Or is every 2000 to 2006 GMT800 exactly the same?

K-Seal has bought me some time with my heater core. About a year ago I was smelling coolant inside. So I tried the K-Seal and it worked. It's not like the old Bars stop leak with the goopy tapioca pellets that clog things up. K-Seal is a ceramic based liquid that goes where it's needed. All I can say is it's still working and no coolant leaks.

Amazing auto manufacturers in even late model cars are still burying the heater core. I've had people get quoted 2k+ to replace heater cores in Toyota , Honda , ford , all makes. I swear when they want to build a new car they go over to the bin of heater cores, hang it from a piece of rope and let the robots build the vehicle around the heater core. On the Yukon you just need to take your time. If you go chopping up sheet metal you will forever have a rattling dashboard.
