The bolt on the bottom of my alternator fell and is lost, i have to know the size of it to replace, anyone know the answer?

LOST THE BOLT,?
ASK NISSAN DEALER.????????
THEY SHOULD HAVE IT.
IF AT WITS END
REMOVE THE RIGHT SIDE BOLT
GO TO ANY AUTOMOTIVE PARTS STORE ON EARTH
HAND BOLT TO CLERK ASK FOR A MATCH UP.
OR MEASURE IT. WITH PRECISION CALIPERS
TO GET SIZE. dIAMETER AND LENGTH.
SORRY NO PARTS SALES HERE,

lost it? or just stipped out
it is metric for sure 8mm or 10 or 12.
all I do is measure it but not if lost
USA car?
all dealers ended new cars sales here and only 2 parts sales stores here. so parts are hard to get but not bolts.
a shop finding this and lost
uses spare bolts in a abox metric to find a tread match.
then with the KNOWN length next.
the main long bottom hinge bolt.? lost is super rare to lose.

If you cant find what size they are, take one out of another window and go to a hardware store or fastener shop to get the right size.

Most likely yes, it is an 8. Best thing to do is take the bracket off the alternator to remount it. Then put the alt back on with slide/adjuster loose.

GO AND SEE YOUR NEARESTSERVICE HYUNDAI DEALER,I
AM SURE THEY WILL HELP U.

the head size for socket size or actual bolt spec.?
you lost the bolt (not stated) or just want to unscrew it?

I'll'' guess at lost.
its metric.
and is 6mm or 8mm ? in size. (i bet 8)
buy some 6 and 8s in the store and see if one fits.
if one fits , you now know the diameter in mm and the pitch.
now buy the correct length (use a ruler)

12mm 175 thread will do the trick
