Bolt Size

[slinky18]

I am new to the forum and new to owning a Yukon. I just bought a 1999 Yukon SLT a few days ago. After looking at the engine I noticed there is a bolt missing. I have included pictures. Does anyone know the size of this bolt? I have not been able to find a good diagram of the engine. Is there anywhere on the internet to get a service manual for this model in PDF form?

gm 11515756 BOLT,HFH, M8X1.25X20,17THD,18 O.D.,10.9,7114M(HTR OTLT HOSE CLIP) about a $1 each at a dealer.

Thank you. Do you think one of these could be had at a local hardware store or should it be one made specifically for this?

 

[SunlitComet]

you can get something like that at a store. i recommend these whenever possible because it was chosen specifically for the application, bolt size, type and size of head, surface finish and coloring.

it just works.

Yeah that is what I was thinking. I just don't like the local GM dealer here so I try to avoid them if possible. Thanks for the info.
