340 Overheat / Radiator Geyser

I'm going to try to do the timing this week. I can't open anything up with it at this point without breaking a lot of rules in the building, such as sneaking my hose through an opening in the trash room door, and connecting it to a faucet in the sprinkler room (no, it's not part of the sprinkler system) so I'll have to wait until Sunday now when maintenance and management are not here. I'm sure one of the lib****s in the building will rat me out anyhow though.
