On my '05, V8 Tahoe with 64,000 miles, we noticed an distinct antifreeze smell the other day while driving. When we got home, we noticed antifreeze leaking (dripping) onto the rear tailpipe (passenger side). The leak was coming from above the tailpipe where two hoses quick-connect to what I assume to be the rear heater core located in the rear quarter panel. Question 1-Do those quick connectors have rubber seals that might have gone bad? Question 2-Or do you think it is the heater core gone bad? If it is the heater core, any advice on replacing it or is it a straight forward repair? Thanks!
