For the head bolts on the ej255 if I remember right a 1/2" socket won't fit where the bolts are in the water jacket right? It seems it's hard to find a 3/8" in 12 point in that size unless the online search is not showing all the sizes

I don't memorize my tools and step but I feel like I use a 14mm 1/2" socket on EJ25 head bolts, but maybe I grab a 3/8"...

 

order it if you can't find it locally:

Home Depot and Lowes have it. I prefer Lowes Kobalt brand.

Better warranty.
