toolbox is in the apartment and dont want to have to keep running back and forth. tia

 

its a 15mm

 

Could also be a 13mm for some reason GM cant seem to make up there mind on which drain plug to use. Most all 99-06 trucks and suvs are 15mm, 07 classic and nnbs will be either or, some are 13mm some are 15mm.

 

Hey, I have a stupid question. The USA uses imperial measurements. (feet, inches, etc.) Why are all the fasteners on vehicles metric? I never really thought about it before since my truck is made in Canada, where we use the metric system.

 

The same designs are used all over the world so having everything in metric is just much easier than having one version with standard fasteners in the US, and another version for everyone else, just isnt practical.

Interesting enough though, most of the axle fasteners are standard.

 

Well, you learn something new everyday! That makes sense.

 

They need to give up the SAE standard already and stick with the metric!

 

I agree with using metric tools, but I'd never wanna give up inches, feet, miles, pounds, gallons, and quarts.

 

Yea no kidding. An advantage of the standard system is its rather easier to see if you made a conversion error since its not a base 10 system wheres in metric its easy to misplace a decimal. Like inches to miles, its 12*5280, but mm to km its 10*100*1000....how many zeros was that?

Also somone saying, "dude I just dynoed my truck at 485kilowatts!" just doesnt have the same effect as someone having 650 horsepower

 

kilowatts ftw hahahaha
