Always block the wheels and use jack stands when working under the car.

Use a big piece of cardboard to lay on when working under the car, if you do not have a creeper. It makes it easier to slide around under there and if the concrete is cold, it allows you stay there a little longer!

 

Always wear shoes, sandals don't count you will learn the hard way if you don't believe me.

 

Always disconect the battery! too many times did i forget and almost shock myself

 

My grandfather taught me how to remove bolts that had no top and were screwed into something. Like its just a stick of thread. Take a nut and screw it halfway on then put a second one on and tighten them together. then unscrew the bottom bolt and voila it seats against the second and the bolt screws right out.

if youre running any type of wireing through tight spaces, tape the wire to a straightened out wire hanger, they def help get the flimsy wire through tight spaces easier

 

How about,

Whenever your bolting something up that's held on by more than one bolt (which is almost everything), never tightened any of the bolts (including finger tight) until all the bolts are at least started.

 

Here's one ive heard about a head breaking off of a bolt flush with the surface. It does require a welder but its ingenious. If the head breaks off get a nut with an opening slightly smaller in diameter than the bolt (to prevent from welding to the other surface) and weld the nut to the bolt, let it cool down and now you have a new head. BTW a weld if done right is supposed to be stronger than the metal itself.

 

i like this one ill have to remember that

 

How about lefty loosey righty tightey? haha when changing your oil break the plug loose and once its hand tight push in as you back it out, then pull away quickly to not get oil all over you
