This can't be this difficult!

I'm installing a bypass coolant filter system today...got everything installed other than the removal of the 3/8" plug on the water pump (just below the thermostat on the right as I look at it). It looks like a 3/8" plug and it looks like I ought to be able to just tap a small 3/8" breaker bar into it and turn it. I cannot get the end of the breaker into it...tried short extension, tried 3/8" drive ratchet...nothing. I am almost at the point where I begin grinding down a short (2") 3/8" extension until it fits. Please, tell this old geezer what I can't see for myself. Is it a 3/8"? I even tried a 3/8" allen wrench thinking I just can't see well enough anymore. Any help would be appreciated mucho (my Ray Charles smiley)!

Neal,

If it is not the stock pump, but an after market, it may be a metric size allen plug. Just a thought.

It is the stock pump...I can't see well enough to be sure it is 3/8" square or 3/8" allen. I think in the morning it is grinding time on a cheap 3/8" extension...it is too late to keep at it and I am frustrated .

I just put on an Airtex water pump a few months ago, I used a 5/16 allen socket (3/8s drive)to remove the plug. I'm pretty sure I bought the 5/16 allen socket when I did my coolant filter on my OEM pump. Hope this helps you out Neil.

Do what I have done...take a digital picture.

Hey,

Sounds like my life story on mechanical things. My wife wonders why I hesitate to start some jobs, then I remind her of ALL the past jobs when Murphy needed a laugh. At my expense, of course.

What I do if I can't see it is take a digital pic and see what the HECK is going on. Then I know. Just put it on macro (on Sony that means make sure the flower is visible on the view screen) and see what 's up.

Any who, that is how I do one small, little trick.

Donnie

I remember using an allen driver on an extension to get that plug out when I installed my water temp gauge. I do not remember the size off hand, but I think Chris is right about it being 5/16.

Drink a beer, Bud. It will be there tomorrow and your muscles will be well rested.

My original w/p had a 5/16" internal square drive plug. I have a Snap On set of sockets for these type plugs. You can grind down the threads of a 3/8" bolt into a square (or use 5/16" square stock) and then turn out the plug with wrench or socket.

Dang -- 5/16ths?? Why in the hack would they do that?? I haven't pulled mine, but casually looking at it, I would've assumed 3/8ths. Thanks for that tip, Roland!

Hmmm. I would have swore that I got mine loose with a 3/8" breaker bar. Stock pump as far as I know.

That was the ticket ...5/16" square plug. I ground down a 3/8" bolt with a 3/4" head and it came out like butter. If anyone needs a 5/16"" water pump plug removal tool, just give me a shout. Thanks everyone for the help and advice...what a country (and forum!!!)
