okay, okay... thats an exaggeration. but i tried to inspect and r&r my monovalve - the part with the torn diaphragm and all. it turned into a minor disaster. first, all the coolant drained out onto the pavement when i opened it up. two, i couldnt get the valve out of the housing. it was completely stuck in. i tried to be gentle, but eventually the whole outer housing just sort of popped apart. and, more crucially, i broke one of the thin copper wires running to the electrical connector. i can still the the broken lead coming out of the coil, but its not connected to the switch.

it seemed like such a simple process. alas, i am a novice. i sort of pressed it all back together, put it back where it came from, topped off the coolant, and gave her a test drive. heat came on, no more coolant spilled out. but still, i have to go get the thing fixed now. yuck.

where did i go wrong? that thing was really wedged in there.
