My 330ci belts broke and i have to replace belts and the P.S. Pump pulley( the after market shop) charged me $290. Now they recommended that i should replace the A.c belt tensioner pulley bearing and the Main belt tensioner pulley because those load/worn. I want to take my car on a road trip but i'm afraid the belts broke again. To replace those 2 they'll charge $450. Anybody have any suggestions about the price? I wonder if i can take the car on a road trip like 1000 miles then come back replace later. Any suggestions ...Thank you.
