Product Q&A

Are these stud bolts for the exhaust manifold flange to downpipe connection or are they for the exhaust manifold to head connection?     I need the stud bolts and nuts for the exhaust flange to downpipe connection where the donut gasket goes. There are 3 studs in a triangle pattern on each side and it seems that finding them would be fairly simple but not so much for the 5.7L engine. When I google what studs I need the search comes back with Dorman 03133 and in many of the descriptions it lists 1997 Silverado K1500 5.7L as compatible but when I have ran my truck information through multiple "see if this part fits" wizards they all say "this part does not fit"     The ones currently on my truck are rusted and threads are gone on some so I need to be sure the replacements I have are the right ones because I have no doubt that some will snap like twigs under pressure and have to be drilled and tapped and after I start taking it apart I am stranded with only parts on hand until I get it back together.     My question is if these are the right studs I need and if not do you have the ones I need?     Thank You       Wade BuckBucknastyDec 06, 2022
Best Answer:Hi Wade, I'm pleased to assist you. Further investigation revealed that the studs for the manifold to the downpipe and head connections are the same. Because the existing studs on your 1997 Chevrolet K1500 Silverado 8 Cyl. 5.7L are too rusted, we recommend purchasing the set of two, as the other set will soon follow. It will save you time and labor costs to do the replacement only once. Click on the link below to view and order at 43% off the regular price today, while supplies last. I hope this is helpful.

Can this be used for the throttle body as well? Are these 10mm bolts?Joe B.Aug 31, 2020
Best Answer:Hi Joe, This stud bolts are for the exhaust manifold, not for the throttle body. It is best to consult your trusted local dealership/automotive shop or a good repair manual for the correct bolts you need.
