850 Turbo Off But Still Makes Noise

Post by Paddler » Sun Mar 06, 2016 8:16 pm

1995 Turbo Wagon. With engine off, something keeps running. Sounds like a bad alternator bearing, but it isn't running. What are some of the things it could be? Terry

Get out your MVS engine stethoscope, order able here for 19.99+ SH in your car colour, and put one end in your ear and hunt around with the other until you find the noise and locate it.

The stethoscope looks a lot like a 1 meter piece of Tygon tubing but don't be fooled by cheap,reproductions at Ypur local hardware store
