Water Pumps A/C vs No A/C [A1/A2]

[scirocco.gtx@juno.com (Mark A Peele)]

There seems to be some confusion about waterpumps.

The waterpump on a no a/c VW is the same as the waterpump on an a/c VW.

The difference is in the pulley, which is held on by three allen head
bolts.

having said that, there are two watercooled waterpumps (A1/A2 chassis).

Up to about 1980, VW used a 40mm hub on the WP. After that, VW used a
30mm hub.

The WP on my 1990 Jetta  will fit my 1982 Scirocco, will fit Kristen's
1978 Scirocco, etc. etc.

All my parts lists indicate no 16V waterpump, so I assume the waterpump
for a 16V is the same as an 8V.

Mark @Adirondack or Mike @ Virtual World can confirm this (please)

If you have an early Mk1 (like Kristen's 1978) - you can upgrade to the
later 30mm. You'll need a new pulley too.

***I know nothing about A3s.
