[Vwdiesel] 85 Jetta turbo diesel auxiliary radiator fanmysteries

[Tony and Lillie]

My 2 4000Q's outside both have 5 blade fans. The first two #'s are missing 
off one, the remaining is --9 959 455. The other has no # left on it. 4000's 
usually start with 85- for the part # from 85-87, hence the type 85 chassis 
designation. 79-84 4000's are type 81's. That rubber piece is to drain the 
fan of water. The reason they do it that way is to discourage water from 
coming in through that hole, but still allow it to drain. Much like the MK1 
raintray drains.

It definately sounds like a bad connection at the connector. Pull it off and 
check it out. I'll bet you find either a bunch of corrosion or a loose 
connection.
