OK, I am ready to get torched for this idea but here it goes...
I have a 2005 Chevy Colorado (5cyl) with 150k plus miles, that I am 99.9% sure has a heater core leak. I am thinking of disconnecting the coolant hoses from the core input and output. Then I would route some coolant mixed with just a bit of BARs Liquid Aluminum only into and out of the heater core. I realize I have to find a way to pressurize and heat the mixture. IF I am successful sealing the breach in the heater core, I will then flush it out with water to remove any of the excess BARS. I realize this is a long shot, but if I use just minimal amounts of sealant and flush it out well right after, I won't risk exposing the rest of the system to the sealant. If the sealant ruins the heater core, I'm no worse off because it is trashed to begin with.
I really respect the knowledge on this forum and know that the only way to FIX this is to replace that core. That said, for a non-professional, a heater core replacement is a tedious and time consuming job. The vehicle is not worth the cost to have this done professionally.
Any chance this idea would work? Any advice or perhaps a different product then the BARS Liquid Aluminum? Knowing that the stop leak stuff is cancerous to the whole system, is this a valid way to isolate it only to the damaged heater core?
Any comments or suggestions would be appreciated - even those ripping me for even considering this!
