Well, after back-washing and cleaning my cooling system today I thought I had it all figured out. The heater was actually working.
Then all of a sudden while driving down the highway tonight, my jeepchick says.. "Something is wrong, it doesn't smell right." (Lucky she was there, my nose was blocked.)
Anyways, the entire system had drained itself through the large (2"-2 1/2") plug on the drivers side of the engine block.
It's a big rubber plug with a metal cover on it and a nut on the top.
It seemed to have been dislodged and was just (luckly) sitting on the heat-sheild under the manifold.
Anyone have any info on this? To put it back in I assume I slacken off the nut, push it in, and tighten it up (expanding the rubber outwards?)
Heh, I was so excited at the same time as being paranoid about my Jeep.
I hopped out with my brand new extinguisher as smoke.. (really steam) poured from under the hood.. poped the hood and was dissapointed by the lack of fire...
Oh well. I guess it didn't burn up in the woods, which means it's still not finished.
