Ok, so I may be silly for not knowing this; but on the a/c lines you need to use two wrenches. But they have a set torque in the FSM, and whenever possible or I deem necessary I do try to torque at the appropriate values. So how would I torque these? I've always used my 3/8" torque wrench, so now I'm confused how I'd torque with two open end wrenches make sense?

 

its called a crows foot...

 

Are those the little things that go on the ratchet? Ant it doesn't screw the torque rating up?

 

Indeed, a crowfoot wrench.

 

Not by an appreciable amount.

FWIW 90% of the fasteners on the car have no need to be properly torqued with an actual torque measuring device.

 

Man, i didn't know these existed...I'll have to pick some up.

Good for inner tie rods too.

 

 

When using a crows foot, if you torque with it at a 90 degree angle, it does not change the torque value. With it straight on, you usually want to reduce your torque setting by 10%. I usually torque everything, but that is how I learned how to wrench in the military.

Agreed. Use the torque wrench for a while with fasteners of various sizes and get a feel for how tight they are when you use the torque wrench. Then you can go by feel a bit more sensibly.

IMHO, a little practice with a torque wrench, and don't use fasteners that don't thread smoothly, and you can just assemble by feel using any type of wrench. Critical stuff like lugnuts, suspension and cradle bolts, exhaust flanges, though always get the torque wrench.
