Q: Timing belt recently replaced now it makes a loud when I drive fast or rev engine

asked by on June 20, 2017

I had my timing belt replaced yesterday and it makes a loud noise when I drive past 40 mph and the car shifts gears. It's sounds like a loud vibration noise and a belt whining noise at the same time. What could it be? Is it safe to drive? Also the crankshaft sensor was changed the same day. I have a 2002 Hyundai Santa Fe

My car has 170000 miles.
My car has an automatic transmission.
