Bolt Torque specs

[pmetz1967]

Can anyone inform me what the Bolt Torque specs are for the upper torque strut to mount/bracket "dogbone", and the four mount bolts to the radiator support? I own a 97 Pontiac Grand Prix GT N/A Thanks

I know this isn't the answer, but torquing isn't absolutely necessary. I never torque them, just tighten them til it's good and tight. I'm sure others do the same.

I broke my left one (passenger side) going too tight.

 

I would think around 50ft/lb is good.

i didn't think there would be an actual torque spec, but alldata is saying 19 ft/lb.

thats it?

[RobertISaar]

that's what it says.

 

the engine side bracket is set for 35 ft/lb.

that bracket is a pain in the ass, one of the bolts i couldnt get to unless i ripped off the throttle body

Ok. I got these numbers from a tech I know but he wasn't 100% sure: Torque Values

Engine Mount Bracket Bolts - 75 lb-ft

Engine Mount Nuts - 35 lb-ft

I'm confused on which is which. Are the Engine Mount Bracket Bolts the four through bolts for the dogbone struts? And the Engine mount must be what is bolted onto our radiator support that the dogbones connect to.

[RobertISaar]

those are the specs for the lower engine mount (the one by the balancer).

 

feel free to read it for yourself.
