I purchased some spare fan belts and decided to do a visual walk through under the hood to be prepared if I ever had a failure on the road. Checking the top four A/C compressor mounting bolts, side adjustment bolt and the hose clip, I discovered that they're all 1/2" in size. I tried a 13mm, but fits too loose; 12mm is too small. Anybody know why these bolts would be SAE in an otherwise metric car?

All the bolts attached to the compressor should be sized M8 (according to PET) which would require a 13mm wrench/socket.

These are definitely metric..did you try both the box end and the open end on the wrenches? Did you try a socket?

Cheers,

They should be all 13mm. Are you using a 12 point socket or an 8 point?

I tried a 6 point 13mm socket and it fits loose. Then tried a 6 point 1/2" socket and it fit perfectly. Also checked with box & open end wrenches with the same result. Very strange...

Eric - I found the same thing - the 1/2" in a 6 and 12 point fit the best. Dont know why....
