Toyota 4Runner Repair Question
Engine noises 2 wks. after timing belts and wp replacement
well unless they have the special tool to compress the timing belt tensioner w/o removing the a/c compressor (tool is an aftermarket creation not a toyota certified tool) it has to be removed to gain access to the timing belt tensioner. so chances are they did move/remove the a/c compressor. were you charged for freon? if so that means they removed it and had to recharge the a/c system. if so maybe the a/c system lost some oil in the process and they didn't add any back in.
another common mistake on these is not tightening the crankshaft bolt to the proper torque spec. if so it might of come loose and caused the noise.
now this is all speculation w/o seeing the vehicle.
