Original replaced last october, made it to march, had to replace again. In July, it was leaking again, where I bypassed it and finally replaced it last weekend. My question - why would I be blowing out heatercores? Everything runs fine, just hit 150K. Never done an "official" flush, but have done the equivelent of 2-3 accidental flushes through blown cores and replacing the plastic fitting that goes into the intake (behind the alternator) which poured out a vast majority of coolant.
Any ideas or comments I'd greatly appreciate~JS
