Is there anywhere to find toque specs to help facilitate changing parts on a truck? I've had mixed luck with calling a dealer/mechanic garage and was wishing there was some kind of dedicated database where you could look up specs by part or year, make and model.

No such animal.
Generic torque specs by bolt size, thead and grade of bolt are your best bet and hard to go wrong.
Engine and trans bolt torques should always follow service manual literature for the specific component.D.Tibbitt, TortuousAugur and AModelCat Thank this. -
How do you find out the grade of a bolt? I've currently got a secondary fan belt tensioner pulley that I need to change out. Being that the mounting material is the engine itself, what torque spec would I look up for that?

A lot of fasteners you just develop a feel for how tight. Unless a critical component or mating surface. Something you droop as time goes by
AModelCat Thanks this. -
You can find a fair amount of specs on google.com. at least I could for my cat engine.
I'm not professional mechanic but I've fixed a fair amount of crap. Personally only time I break out a torque wrench is inside the engine. Anything else I just get a feel for it. But that's something that comes with time and experience I guess.
Generic torque specs for grade of bolt is probably a good starting point for a beginnerTortuousAugur Thanks this. -
The current truck I'm driving I've replaced three air suspension bags, ride height leveler valve, the rear differential torque arm and have to replace the fan belt tensioning pulley, fan clutch, fan belt and engine fan solenoid from what I understand. I don't even know how the fan belt is still on with how the tensioning pulley is angled but it's been holding up so I've been letting it be but figure I should replace it before it does anything obnoxious like busting a hole in the radiator.
The previous operators didn't seem to take care of the truck, from what I'm seeing.Last edited: Oct 20, 2021

Nobody torques anything unless its something like head bolts or bearing caps.
99% of work is usually done by feel.God prefers Diesels and TortuousAugur Thank this. -
