Re: [DML] Water Pump (Pulley)

["content22207" <brobertson@xxxxxxxxxxxx>]

Because I can remove my intake manifold in 3-4 minutes, I may have you
beat on time to change the water pump...

If thin OEM pulleys are so difficult to work with, I'd recommend
pressing a Volvo flange onto the shaft and bolting on either Darryl
Tinnerstet's pulley or a Volvo steel one with the outer belt groove
filed or ground off (to prevent interference with the A/C belt). Volvo
flange is at least 1/2" thick -- presses on & off no problem, no heat
necessary.

Advance computer shows a flange already pressed on their replacement pump.
