Fan Pulley Holder

I was going to try and change my Thermostat and realized I don't have the fan pulley (over the shoulder boulder) holder. Sorry, couldn't resist.

Anyway, I looked online and bavauto wants $40 for one. I know some here have manufactured their own and think with my father-n-laws help I can make one as well.

Does anyone know the dimensions of the bolt holes (diameter and distance apart), half circle and length of the unit?

I may make several of them so us penny pinching DIY'ers can have one.

Thanks for the help!!!

I don't understand the question and I am assuming you are talking about the 325i and not the X5 right? I DIY'ed my water pump recently and I used a 1 1/4'' wrench to remove the fan, and then an allen wrench to loosen the de-tensioner. The bolts around the t-stat should be 10 mm or 12 mm.

Oh ok. People have used a screwdriver between the two blots. Glad you resolved it.

You dont need any special tool to hold the clutch; just whack the wrench with a dead blow hammer.
(you do need a thin wrench to get to the nut).

+1 and if you still need leverage use a screw driver wedged between two water pump nuts. There are mucho threads on this.....(even some pics I did)

Okay..... I wasn't sure if a screw driver would damage anything. I'll search for the pics and make something happen this weekend.

I'll give it a go and let ya know.

Thanks guys!

This is how most people crack/break the bakelite/plastic pulley. The get it sort of close, then chip it.

The holder/screwdriver method is just a hassle; and noobs are going to get frustrated. Just take up the slack and hit the wrench HARD with a deadblow hammer with at least 90deg of clearance.. There's no need to lock the pulley. Unless maybe you've got an ancient E46 and your POs have ignored maintenance.

Perhaps, but Big J isn't a "noob" and has a large amount of common sense so I feel confident he can figure it out. The hammer thing has worked for me on 7 out of 10 auto cars, but not all of them, only reason I mention it.
