Guessing they make a 4 sided Allen wrench for this???

 

Just use a ratchet with no socket.

 

why are you wanting to remove it if you dont mind me asking?

 

Tried the ratchet seemed like it didn't fit in hard to manuver with the ex manifold. I am trying to drain or flush any crap out of the bottom of my block. Machined head new gaskets all new cooling system. Want to make sure it's clean!!!!!!

 

Its a 3/8 square. Maybe 1/2. Use an extension. It will fit.

 

Thanks I'll give it another go!

 

If you have a 3" extension or a U joint for the ratchet that might help too.

 

With or without the extension its too big and it's not the ball stopping it

 

What size ratchet are you using?

 

3/8

 

Maybe try a 1/4 drive socket. One of them will work.

 

1/4 way too small I guess it's a 5 /16 drain plug. 3/8 is just a hair big off to find a 4 sided allen

 

that plugs been in there eleven years gonna be a pain to get out ,then its a small hole aing gonna get much out puling all the freeze plugs and flushing will get better results but thats a pain also good luck

 

I already have the entire cooling system off I was going to open drain plug and stick hose into the waterpump location

 

Reasonably sure it's 5/16".....a short piece of 5/16" bar stock (at most hardware stores) should work.
