I am having trouble getting one onf the coolant drain plugs out of the engine block. I tried heating it up, I have penetrating oil soaking in right now..but it wont budge. The other side came right out. I drilled out the center of the plug and am trying to get it out with an easy out, but no go. Anyone ever wrestle with one of these before and have a good tip on how to get it out. Engine is on a stand at the moment.

thanks

I was always under the impression that these don't come out easy (or at all), so I have never touched them. No reason to really.

Try to find a a big nut and set it on the coolent plug and weld in the center of the nut and that will give you some thing to turn as this has worked for me several times with no problems and if worst comes to worst you may have to go 3/8 pipe plug as thats been done before as well.

That's what we used to do at U-Haul as well. http://www.nastyz28.com/ubb/smile.gif

Stupid Q, but are you turning it the correct way. Just like the taps in the house.

If you do not have a welder like me, go to the hardware store and get a good size EZ Out, drill through the plug, and use the easy out. One word of caution, if that does not work, you are screwed untill you get a welder.

I drilled out the first easy out I broke off using sucessively bigger drill bits. I then heated it up the best I could with a propane torch and let it sit over night with penetrating oil. I then used the next bigger ez-out and snapped that right off.

I am afreaid she aint comin' out and if I were to weld on a nut, I put be screwed further if she still doesn't come out and I got that thing weld on there.

One person suggested that I keep drilling out the center of the plug till most of the plug is gone, then tap on the side to get it to collapse on itself.

(and yes, I am turning counter clockwise http://www.nastyz28.com/ubb/smile.gif

Use the largest easy out that will still leave a little bit of plug to grab on to, no reason whatsoever that plug won't come out.
