Warm air

The truck had been mysteriously "using" water. I replaced the heater core. I swear there were new life forms growing the box that the core is mounted in. It's all cleaned out now though. And, the blower motor, having been lubed and cleaned, stopped making that horrible rattling noise. The worst thing about putting a new heater core in a 70 GMC truck is the fact that you have to pull out the passenger side inner fender to get the thing out. I realize that it's something that I need to be aware of, but I was happier when I didn't know how much rust was in the body of this truck. It's warmer now though.
