depends on whate school you go to.

where we went it was 50% off snap on hand tools
mac and matco also had student discounts of some sort.

 

do not buy irwin tools, or better know as "vise grip" brand. they shut down the usa plant and moved to china, putting almost 300 us workers out of work!!!!!!!!

 

I just replaced the intake, all metric.

Replaced the fan clutch, used M8 to remove the shroud. Used M15 to lossen the belt. Used M13 to get the fan clutch off.

Of course you will have cross over but the factory manual and your Hayens/ Chilton will have several metric sizes listed.

Just trying to help the OP out.

 

Yea, I went an rechecked it, a 7/16 was snug enough to get the bolts off, but it WAS a metric that fit it.

 

10mm is close enough to 7/16
13mm is close enough to 1/2
15mm is close enough to 9/16

But on a torqued metric bolt the SAE will just strip it. now sometimes if you have stripped out the bolt and it was a 9/16 you can beat the 15 mm on with a hammer and break it loose
