it would help if we had an engine size.

could be loose motor mounts from the repair.

why did you have this repair done???

Roy

Repaired yesterday. Engine size 2.4L 4 cyl
Car is 2004, had belts changed because they were old, serpentine was cracking.

If motor mounts would car make a roaring like noise in park and vibrate?

you did not mention timing belt???? was that changed???

roaring??? did a shop perform this repair???? if they did, did you return for follow up for there opinion???

Roy

I will Monday. Picked up car at closing Friday. Wanted some idea of what could be wrong so I could talk sensibly with the mechanic.
Regarding the belts, like I said, I had all the belts replaced, and that did include the timing belt.,crank seal, cam seal, water pump,idler bearings and tensioner bearing.
Car had never vibrated or roared before it was repaired. The mechanic said , perhaps the tensioner pulley was too tight?
Thanks for your assistance...........ben
