Idler pully bolt size

[FIND]

My parents lost the bolt for the idler pulley on the 99 zetec I gave my little sister. The idler pulley broke, bought a replacement, but need the bolt so I can reinstall the pulley and serpentine belt.

Anyone know what size bolt that is so I can get a replacement.

i want to say it's a 10mm but i'm not positive and i don't know the length. if you run by your local ford dealer they can pull the part number and they should have a replacement. i recently had the timing belt idler pulley bolt shear off at the head and it was like 7 bucks. if the dealer can't get you the bolt they should at least be able to get you the specs on it.

it's a 13 mm bolt.

No, it's not. It's a 13mm HEAD. 10mm sounds right for the diameter, I don't know the pitch.
