I should have used the plastic ties.

While mounting my fan brackets to the top of the radiator, I slipped with too much pressure on the drill and popped into one of the tubes underneath. Now I either get a new radiator, or I plug that tube. Angry with myself.

That does suck. If I opt to do the same thing I think I will cut the drill bit and mount it so its just a little stubby deal sticking out of the end of the drill that can only go so deep.

Im still in the middle of my PWM swap. Its been a bit dramatic. I got a new 600 Bosch motor for free, because the junkyard accidently wrecked the fan when removing it (2005 Volvo XC90). Was fine with me because I only needed the motor. ....... Then I cooked that new motor. 100% my fault. I didn't have 10 gauge black wire. So I used what I had, forgot I had red on the ground wire and put it in backwards. Dumb, unforced error, but these particular models do not tolerate being wired backwards at all even for a short time.

I bought another Volvo fan from a 2009 XC90 intended to swap the blade and motor into my SL500 shroud, which Volvo says are interchangeable from 2003-2014, but it appears that in 2007 they started using their own motor and not a bosch unit. I was initially annoyed but now Ive decided I might like the XC90 shroud more than the Mercedes SL500 one I had originally planned. So now I think Im just using the newly acquired fan and shroud.

They are both close, and both are about 4" deep. The volvo is slightly too tall, and the Mercedes is slightly too wide. Ive decided I would rather deal with too tall. But Im convinced either unit can be made to work, and would be even easier in a car with a slightly bigger radiator than a first gen.

The crazy part to me about the 2009 Volvo fan, is its open in the back. Which had me staring at it forever trying to figure out if they switched to a pusher fan, but no. Thats just how it is. There is a cage on the side that goes toward the radiator, but the exhaust side of the fan is wide open.
