I recently bought a 1997 VW golf k2 edition and ive noticed a noise coming from the radiator fan, but only one of them. when its running the fan is very wobbly and makes more noise the higher the fan speed is. i think i need to change out the fan assembly. is there anyone who knows how to do this or can point me in the right direction? Itd be greatly appreciated.

What's up Tex? Your fan bearing is worn out an/or one of the fins . Not much to change out, it's just in a tight spot. A set of sockets is all you need. Congrats on your new purchase! Here's a link for fan price.
