Spiffy Posted April 22, 2006 Share Posted April 22, 2006 so my heater core in my '82 GL is mostly clogged so I was feeling up my heater hoses to see which is the intake and which is return... well the top hose was really warm and the bottom wasn't... question answered... however, when I squeezed the lower hose it was all crunchy inside... I'm afraid... what do you think is in there? old rust? it is crunchy all the way from the firewall to the water pump... I'm waiting for it to cool down right now so I can disconnect the hoses and flush everything out... --Spiffy Quote Link to comment Share on other sites More sharing options...
baccaruda Posted April 23, 2006 Share Posted April 23, 2006 it's time to change that hose; it's the rubber on the inside of that hose getting crunchified. Quote Link to comment Share on other sites More sharing options...
