So, I think my radiator fan isn't working quite properly; it comes on when the temp gauge hits about 2/3, and it's LOUD...I'm guessing this is high speed, because I can't imagine it blows much harder than that. Is there an easy way to test the fan and/or switch? Should low speed come on sooner than that, or is there another, faster speed that I haven't hit yet?

Yup its the high speed! Replacement shouldnt be much more than 30 bucks max, but...now it the time you can put in a lower temp kicker if you want

so the engine wont run as hot, you might think about a 185/195 or something near to that

You might try....pulling off the rubber electrical connection off the sensor and jumping the connections. There are three. One is a ground, the other two is low and high

see if that the fan is working ok....motor that is

Also, make sure the ceramic resistor behind the drivers headlight isn't bad. IF the van has A/C it has one of these. Mine was bad and did the same thing as yours, and it was NOT the temp switch.
