Does anyone know the TAP size to clean the threads on the water pump shaft?
Compliments of Bluebee @ www.bimmerfest.com

I didn't know about this wonderful trick until it was too late.
The last thread or two of my water pump shaft is "sharp" to the touch, such that the fan nut is going on crookedly (details here and here).
I'll bet this next question has never been asked on Bimmerfest before ... but I need to know ...
Q: Do you know what the tap size is for the water pump shaft threads?
BTW: Below is a pictorial DIY of cn90's suggested method. It failed for me, but, only because I had already stripped the last thread or two of the water pump shaft NOT using this method!
