Question type: Maintenance & Repair

It happens when light/slow braking reaches 20 mph /less  or when waiting at light. Barely
touch gas pedal & sound quits.  Van has Braun's Entervan II  system & is locked in kneel
position.  Only 59K miles.  How much $$ to fix?

1 Answer


Would try replacing serpentine belt first and with belt off you can check the bearing on the water pump and other accessories by spinning with hand and listen for a roaring noise while it is spinning.
