ummm lets see if i can remember what i used.. Bear with me cuz I work on cars all day I can't remember every tool i use...
fan clutch tools
I think the fan cover or shroud however u spell it is on by either 8mm,10mm bolts or screws
You will need a 8mm and 10mm sockets
screw drivers to loose and tighten hose clamps
I think thats it I can't remember but it will get u started...
