new water pump whistling

[Phillips, Kevin]

Yes there are different teeth and I believe the changeover can only be
determined by VIN
069 109 243B
   TENSIONER-TIMING BELT
      89 Only   100 - Thru Engine: NF 063969
      89 Only   200 Turbo Quattro - 10 Valve - Thru Vin: 44-K-004457
      91 Only   200 Turbo Quattro - 20 Valve

074 109 243
   TENSIONER-TIMING BELT
      89-91     100 - From Engine: NF 063970
      89-91     100 Quattro
      89-91     200 Turbo
      89-91     200 Turbo Quattro - 10 Valve - From Vin: 44-K-004458

The difference is square teeth or more rounded teeth. The belt tension is
important, it should be able to be twisted 90 degrees on the longest run.
The pump I put in came from Kris Manusha in Canada and it has a bronze
impeller, super high quality unit

    This is my impression also. Just a few weeks ago
    we were comparing camshaft belt pulleys from 
    different 20V engines(NA and Turbo). The
    teeth profiles were different. Sorry, have no
    details on this...
