Just curious: How close is your radiator date code to the production date of your E39

Just curious:
How close is your radiator date code to the production date of your E39?

According to realoem, my production date is 11/2001 and the date code on my original radiator sticker (passenger side upper edge) says 11/21/2009.

Wow. They don't let the plastic cool on those radiators before putting them in the vehicle.

Just curious ...
What other parts have a classic date-code sticker we can reference?
Were your parts also just-in-time inventory like mine (within a week)?

Considering

that the E39 stopped production in 03 and it is now 10. Knowing our cooling systems and the way the radiators are designed as a 'throw away' item if they are close, then you'd better be getting another one ready...cuz that puppy is gonna blow.

My original radiator build date was the month before the car's production date.

The original rad and most of the other original parts I replaced with my recent cooling system overhaul were dated around March 1999. My car "build date" is April 1999.

Incidentally, some of the parts, if you look, have a kind of dial- or clockface-style date indicator stamped into the plastic. One for month and another for a range of years. Best I could tell, all were pointing at 3/99.

So far, it looks like the radiators are built about a month before the E39 is shipped out. Mine, at 1 week, must've been at a rush time just before the dot-com bust!

As for the date code, here is a 2001 date code on my original failed GKR FSU from the FSU autopsy thread.

I came here looking for the radiator date code thread, but it wasn't here.

It's here:
