Heater Core - Puddy
Posted: 16 Oct 2006 19:451970 DODGE CHALLENGER 318 C.I. V8 - NO A/C
We have removed and will replace the heater core. There seems to be a black (very old and brittle now) puddy substance around the core. Do we need to re-apply upon replacement. I called NAPA and they were clueless. I have been directed NOT to use a Silicone.
Does anyone know what this is? I have found nothing on the internet about the puddy.
