I need to flush out a heater core. Ive been there, done that, got the t-shirt, etc.
What Im wondering is if anyone has ever used anything to help flush out the core, like CLR or Rydlyme?
I mean, Im guessing its calcium/lyme deposits that plug these things up the most. So recirculating something threw the core that would clean it out might help, yes?
comments? suggestions?
thanks!
