The Plastic Fan Blade....replace it at 120-130K or so (BMW Only!).
Otherwise you are good to go. |

Also the WP Pulley (BMW only), replace it at 120K or so.

Just curious, what's the logic behind 'BMW only' for the replacement pulley? Or why replace it anyhow if it shows no signs of wear or cracking?
I'm gather my cooling overhaul parts this week, and I "splurged" for the BMW fan, but I think I overlooked the pulley. |

Bearings: made in China vs made in Japan or USA.

You are better off repacking the bearings on a OEM BMW then buying a new China one. Repack OEM = (small automotive pick, remove the rear bearing cover, clean with parts cleaner, inspect the balls for pits and/or bluing, if good then repack with high temp grease, replace cover - it snaps back on) |

You missed your Vanos seals rebuild pack and valve cover gasket kit.

Huh? I think we're not all on the same page here. The water pump pulley is just a pulley, no bearings involved. It bolts to the water pump, which I assume has internal bearings, but that is already being replaced as a unit. I'm only asking why / why not replace part #8:

I will reference this, since it has nice pictures to the thread:

Whenever we mentioned the word pulley, it makes these guys excited ha! ElwoodBlues is right, we are talking about the WP Pulley, which is a piece of Plastic (special plastic). This is a crucial part, if this part goes bad, it creates thousands of dollars of damage! So stick to BMW or if you can find Aluminum Pulley, go for it. |
