Coolant Filter Install Problem

[wils2527]

Has anyone ever installed one of these from Diesel Site?

I was wondering what size the square drain plug is just below the thermostat is supposed to be. I've tried everything and I know it is not a 3/8" drive or 1/2" drive. I have also even tried all metric and standard sized Allen wrenches but to no avail.

Any ideas?

By the way other than that this kit is straight forward and I'm pleased with how easy it was to install other than my water pump problem. Thanks in advance for any info.

dont know what size it is but a 3/8 extension should fit it.if not they do sell sqaure sockets just for plugs like those

Thank you Rich. I will have to make a trip to the tool depot to get something that will work. Good news is the truck is still drivable!

should be able to get the right socket at pretty much any hardware store.im pretty sure home depot would have it if the auto parts stores dont

Yeah I don't trust auto parts stores for tools and such. Ran into our local Tool Depot and they had what I needed. Didn't even cross my mind that they had such a thing. Thank you again!
