The fan override is in the link in that link, if you get what I mean. Note that my pics are based on a 1993.

I wouldn't do the fan override to fix a problem. Repair the overheating issue first.

Not being able to locate my petcock and knowing I only needed to drain off a little I used a piece of vacuum hose (about 3-4 feet long) snuck it down inside the radiator and siphoned off about 1/2 gallon. Do the T-stat and refill, making sure to burp the baby.

Now all you guys laughing at me, which side is the petcock on? d/* or p/*? Cfoote even looked and couldn't see it.

driver side, i hade to take off that plastic underbody piece to get to it, its really hidden, it will actually actually end up draining thru a hole in frame on the bottom

and like i said twasnt the tstat, big question i had had is what exactly is smoking off and where is it coming from? cuz my coolant levels havve gone down, havent checked oil but i doubt 200 degrees would be enough for oil to smoke

If you don't have the money... do you have the wrenches? Intake is intake and would need to be done.

All I've heard people on the Series II replacing was lower intake...upper doesn't normally seem to fail. Us Series I guys don't envy the intake problems.
