I’m pretty annoyed right now… I replaced my leaky heater core about two years ago. To my surprise I pulled out the factory original (or replacement). It had the FoMoCo stamp on it and was just leaking a drip here and there. The other day my new replacement one started leaking all over the place! Lucky I have rubber floor mats and I was almost home or my (already crappy) carpet would have been even more ruined! So now I have to pull apart all of the new crap I rebuilt under the dash ( I know it is not as hard as new car but still!) and replace the stupid core yet again… just two years later. What is a good brand to buy this time around? The one from mustangs unlimited just didn’t cut it and I’m not going through another winter without heat! (and yes, it was installed perfectly just for those who doubt! =-) )
