I stored my click torque wrench in a mid-high setting. Is it ruined?

If you have one of these, you could easily test it yourself. I admit: this is not the most accurate way to measure the callibration, but it's probably the easiest way to give you a rough idea. (Image ...

How to interpret torque spec ranges?

Those are the limits. Going above specified torque can damage the thread in the nut or engine block, or on the bolt. Especially aluminum and light metals are prone to failure due to bolts and nuts ...

Which fasteners need the most torque? Will just one torque wrench with a wide torque range be enough?

TBH with you, unless I'm doing some serious wrenching, about the only thing I use a torque wrench on is the wheel lugs. Beyond that, it's all done by feel. Obviously I'll use one for things like ...

What does, "Tighten with specifed torque at curb position of vehicle" mean?

This means that the final torqued setting has to be done with the vehicle sitting on its wheels so the suspension is in the "normal" position. So this can be on the pavement or when on a ramp but the ...

How to interpret torque spec ranges?

Your torque wrench is not 100% accurate, so aiming for the limits may end up over or under-torquing it. Best to go for near the middle of the range. A modest torque wrench might be accurate to +/-4% ...

How does turning a single bolt 45 degrees and then another 15 degrees differ from turning it 60 degrees?

I would suggest that the difference is down to how the torque is applied to the pulley (I assume that is the part with the crank bolt you mention). Some pulleys have a taper fit and using a three-...

I have a required torque of 30nm +100° +-5°, I have a torque-wrench 40nm-210nm. Can I convert the required setting to my TW somehow?

There is no conversion. The reason is, the degree requirement implies a need to stretch the bolt. You cannot do that with torque alone. The initial torque is to ensure you are at the proper starting ...

Does this torque setting seem correct for a crank-pulley bolt?

Yes, that seems reasonable. Be sure you are NOT re-using the original bolt. When used like this, called "torque-to-yield" the fastener has been stretched beyond its deformation limit and ...

My guess is you have already overtightened them and you should really disassemble the manifold and identify why it didn’t seal correctly. Don’t just tighten more. You may need to get a new gasket. ...
