Will I loose a ton of coolant when I replace my old fan switch to a lower temp switch? What is the best way to do this without killing my driveway?

The fan switch is several inches down on the side of the radiator, so yeah, you could lose quite a bit. You have some choices:

1 - Get the car on a steep incline - ramps or jack up the front end
2 - Drain some of the coolant out
3 - Work very, very quickly.

just be quick about it. have the new one in hand and ready to thread into the radiator immediatly after you pull the old one out. sure you'll spill about a quart but nothing serious.

Leave the cap on the reservoir tank too, that will help slow the loss.

I flooded my college apartment when I tried to replace the hot water faucet washer WITHOUT turning off the water cause the shit off was rusted shut. It was pretty fucking funny at 2 am having hot water gush out. I did it though.



I will probably try to siphon out much of the coolant in the reservoir and my driveway is already at a nice incline.

Thanks for the advise all.
