Well, I tried giving that overcooling problem a go. The overcooling isn't really something I'd be worried about if the car would run fine slightly below its normal operating temp. So really my focus should be on that part, but VolvoClearingHouse, in another thread, told me I could get noticeable butt dyno results by removing my mechanical fan (yes, he knows where I am and what the temperature is like). I'm very hesitant, but I figured I could give it a try. I took out the fan aaaaaaaand...
put it back in. The bolts shanked out with the fan removed and I didn't have any washers on hand that would work to back those out a bit. That'll have to wait till my stuff gets here (oh yeah. The container containing all my household goods? It's been quarantined... They found something "gun shaped". It's my kid's telescope. Apparently it has to go to a lab for testing.)
But did you know the blades on the fan aren't evenly spaced? Again, this goes in the "I'll assume the germans know what they're doing" bin:
Also, unfortunately, there isn't an easy way to remove power to the electric fan. Aside from shutting off the ac that is...
Good times
