Q: severe rattling on right side of engine, near alternator

asked by on

car can be moved under its own power, but cannot be driven

My car has 188004 miles.

The engine crankshaft pulley is broken most likely. This car had a recall or technical bulletin years ago on replacing this pulley. It may look okay until you run the engine and it will wobble or not turn any accessories and make a loud rattle. I cannot locate the exact TSB number about this right now. The problem should be verified by a technician before going any further. You can find a qualified professional through YourMechanic, who can come to your home or work and diagnose your rattle.
