Hello all,
I’m at my wit’s end and financially strapped. I own a 2001 Chevy s10 4.3 litter engine 2 wheel drive truck. Every time I accelerate I hear a hissing air sound like a vacuum cleaner from the belt/pulley areas. I’ve changed the alternator, a pulley, the tensioner, the air compressor, and the power steering pump is only 5,000 miles old. The sound has not gone away. I have no engine overheating or anti freeze leaks and the power steering works fine. When I first changed the power steering, the wheel was super hard to turn and it would sporadically get easier; now it us easy to turn. What could be causing this sound? I rather not change the water pump now. Please help.
Thanks.
