I went out to the truck today to see about spending an hour of TLC, and I found this pooling in the cab:




I am guessing it is coolant? Is that how the heater works? Circulating hot coolant over heat exchangers?

Anyway, at least I feel better about the heater. I had thought it was a 40 year old gas heater and that I was going to blow up my truck when I tried to use it.

Let me know if there is a likely culpret aside from just leaky hose.
