#6 of 15 rattling - heat shield strap/bracket by mrnoggins

May 01, 2007 (10:07 am)

Our '99 S-10 (4wd manual) has a wicked rattle that has been narrowed down to a missing strap/bracket from the heat shield. With only 1 of 2 straps in place... it rattles like a German tank.
 
On another note, we just sold our '88 (2wd manual) a week ago with 303K on it. Regular oil changes and minor parts replaced over the years; nothing bigger than the water pump in 7 years. We live in a city that has emissions testing and the truck passed easily each year. I've met 2 people with the same vintage s-10 with over 400K on the odometer. Great little trucks! (Expect more KM out of yours panache.)
 
(The only reason we sold was the screaming deal we got on a pretty blue '94 s-10 with low-low kms!)

I have a loud rattle in the center of my 2002 Chevy S10 ZR2. It is very loud and sounds like cards in the spokes of a bike. It is constant and only quiet when the vehicle is in neutral. What is it and how do i fix it....cost? Any help would be great.

I own a 1999 S10 and it rattles very loudly at idle and below 10mph. I found the catalytic converter to be the cause. More specifically, the internals of the converter were "rattling" around inside of it causing the noise.

Sometimes the catylitic converter's heat shield becomes loose when the spot welds fail. When this happens it creates a terrible racket.

Check the oil for gasoline smell, them V6's had a lot of fuel leakage problems under the plenum.

If noise is with a cold engine and goes away hot, maybe infamous piston slap.
