I had the alternator vee belt break while driving and researched how to fix it off the p-car diy website. the problem is I can't get the 15/16" (24mm) bolt to release. I bought the special Porsche tool to hold the shaft still but it won't come off. I tried penetrating spray and a little heat. Finally I added leverage and broke the Porsche tool off at the spines. Any ideas? Am I doing something wrong?

Facing the rear of the car - the nut turns counterclockwise and the shaft turns clockwise .... right? No intention of being insulting, but sometimes we get it wrong - as I almost did today hanging under the SW of my W8 trying to release the seat bolts ...

I prefer the squeeze technique for such nuts .... 24mm wrench @ 12 o'c lock, and 10mm triple square tool in the alt end shaft @ 11 o'clock .... at the tip of the wrenches, squeeze them together with all you've got ..... should be more than sufficient.

Yep...squeeze technique. I use 15inch wrench and slip a pipe over the triple square tool so it's the same height as the wrench. Then squeeze.

+++1 on using a pipe as extension to the triple square as leverage, then a beer.

So did I, but just to compete the Porsche tool kit.

Call your local Snap-On dealer and order one or both of the following tools:

10 mm Triple Square bit (to be used with an 11 mm box-end wrench).
Part number: FTSM10E2, $10.00


and/or

10 mm Triple Square Stubby XZN (to be used with a 3/8" drive flex handle).
Part number: BLPXZNM3810, $7.60


Coat the threads with some anti-seize paste when you put it together.

+1
Plus a few drops of penetrating oil on the thread AND where the nut faces the pulley.

Thanks everyone. I'll give it a try.

The Porsche tool is sh*t. Get the Snap-On socket. Not some threads you'd want to mangle.

Now I'm thinking, I should have bought 2 sockets...1 for the car tool kit (to keep the junky Porsche tool company) and 1 for the tool box.

personally, I used the geolab method of inserting a screwdriver into the alternator blades to prevent the pulley from moving, and then used a regular old adjustable wrench. worked a champ.

when's a good time to get this replaced? any pt of reference as when its due for a change?

this isnt catastrophic like a timing belt where if it snaps, your engine is screwed right? looks like it turns the alternator, the fan, and the ac compressor if its attached.

Quadcammer

you are correct. There is no immediate "screwing", but if you drive without the fan belt, you will be screwed in short order.

Belts are soo cheap, I'd probably do it every 2 years or so.

bavarian06

good to know. is it a lot more work to change it to a RS pulley by chance while everything its already unbolted by chance?

I've used a helper's hands to hold the fan blades in place. I wouldn't mess with a screwdriver. Those fans have to be expensive to replace, no?

Quadcammer

holding the fan doesn't help with the alternator shaft.

The fan is about $450ish, but its difficult to cause damage.

The alternator has blades. You put the screwdriver through the holes in the fan and engage the alternator blades. Hold that with one hand, loosen bolt with the other. As long as you apply steady pressure, there is very little chance for damage.
