If the heater hose touched the coil in hot weather, it wasn't helping any. Unless the coil was a pile hotter than the coolant.
Jason, Glad you found the source for your trouble. I have been reading through this thread every time you updated and was at a loss since you were checking all the usual suspects. I will keep this in mind if I run across something like this.
I have to say that this one took me back to school. I re-learned a few things in the process. Im also finding that the car is starting up easier too. It was never hard starting, but now its starting on like a 1/2 a crank. Im almost tempted to put the points back in! :error::laugh:
Problems like this are a hit to the self-esteem, but they're rewarding when you figure them out...good work! I'm suffering through electrical maladies myself on my Dirty Dart...now I'm pretty sure I understand why I've never bought an old Mopar before. Printed circuits, burned out gauges, faulty windshield wipers...yuck! It'll take me a year to sort it all out.
Aaron, my buddy has a 68 GTX. He was burning up the ballast on the firewall, the ceramic one MOPAR has. Anyway after tearing out the entire dash, it was traced back to a break/grounding of the printed circuitry that actuated the fuel gauge...absolutely maddening p
That's what I'm talking about! Ugh...I had no idea how idiotic the electrical systems were on Chryslers! I just spent two days on windshield wipers. Wipers! When was the last time you thought about wipers? My next car's going to be a GM or a Ford. But then again, I don't need any more cars!
