Unless the header tanks are rotted out, a plugged core could be replaced by a rad shop rather than having to find a replacement. My experience with the 4 cyl heaters is the core rarely leak or plug, I think because coolant circulates at all times.<div class=""><br class=""></div><div class="">Yours</div><div class="">Vern</div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Aug 15, 2017, at 2:00 PM, Steven Dibdin via Rovernet <<a href="mailto:rovernet@rovernet.org" class="">rovernet@rovernet.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">Lance,<br class=""><br class="">I would be more inclined to think the problem is with old foam gaskets and<br class="">seals internal to the heater unit.
