What Size Square-Drive Wrench for Stock Oil Drain Plug on '05 CTD?

[RockinJ]

My local 5-star has been doing the oil and filter changes on my '05 5. 9 CTD since new, but ever they since they left the filter loose on the last service (what a mess!), I've decided to start changing the oil myself.



In preparation for my next oil change, I crawled under my rig this weekend to check out the drain plug. Looks like it takes a square drive ... does anyone know what size this is?



Thanks!

Every truck I've ever had has a 3/8ths drive hole.

Yup it is a 3/8 drive ratchet or extention.

Yup 3/8" drive will go right in. I'll third that!
