Interesting you have the old fan blade design. The turbo models all got 9 blade fans. Do you notice your car runs a little warm?

[@SquarebodyTruckCamper]

I never noticed the car running warm (it would run at about 90C)… but after owning the car about 1 year, I bypassed the mono valve and installed a gate valve. I open the gate valve in the winter to allow coolant to heater core and close it in the summer.
Ever since I made that modification, whether the gate valve is opened or closed, the engine temp gauge runs at 95C normal operating temp and 105C pulling hills (climbing 1000 ft).

3 months later, any issues?

[@SquarebodyTruckCamper]

3 months and about 4000 miles later and vacuum pump repair is still holding strong.

@@SquarebodyTruckCamper I must have done something wrong, went from 10" before rebuilding to 0" after!

[@SquarebodyTruckCamper]

@@JAMESCC88 that’s a bummer. You may need to get another used complete pump to swap in when you remove it next time.
