Hello all, 99 Tahoe LS 5.7 4dr. Went through car wash now the motor is screaming. The shop has changed out the idler pulley, belt tension pulley, alternator, and 3 different belts. It sounds like it is coming from below but they say they can't locate it. 400.00 dollars and still no help but the new parts look nice... Suggestions are appreciated!!
