How can I tighten the bolt thatattaches the electric fan on the engine side? It's ticking pretty bad when the air is on and if i reach in i can move the fan in all directions. It doesnt look like a standard bolt but really cant see too well Im affraid will have to take the radiator off just to get to it?? Tried to find this in a search but had no luck but someone had posted that it is a common problem.

 

nothing?
