My 1985 300D Turbo is making a clattering sound from the neighborhood of the power steering pump.

Any suggestions from anyone who may have experienced this?

Check belt tensioner, press it with a broom handle while running, see if the noise changes.

An 85 has adjustable ancilliary device pulleys for tension.

Did you check PS fluid level and condition?

AC compressor is engaged or not?

Brake booster has good vacuum (to check vacuum pump near PS pump)?

Get/borrow a stethoscope device to isolate the sound. You might try a hard plastic vacuum line to your ear.

On it. Thanks

The 85 300D does not have a belt tentioner.

As mentiond check the PS fluid level.

With the engine turned off, see if the pully is loose or the bearing at the pump.
Also check the bolts that mount the pump to the bracket. 3 I think.

Wiggle the fan to check the fan clutch and water pump for looseness.

Could be the AC compressor pully/clutch.

Check the crank pully. those bolts have been known to sheer off also.
