Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hello, Eddie here and I will do my best to help. Is the belt in line with the harmonic balancer pulley? I've seen the rubber in these balancers fail before, the harmonic balancer I'm speaking of that goes on the crank? try to wobble or turn that pulley on the crank and see if it's tight, or any signs the rubber is loose or coming out.
Sorry for the delay, we are experiencing some high volume this evening.
