broke alt bolt

[bill81vette]

I had removed the A/C comp and AIR pump,earlier this winter,as I wanted to take the radiator out and put new air seals on it,as well as new upper and lower radiator hoses,and clean up the front of the engine(degrease and such) b4 the driving season started.So today I decided to attack the alternator,pull the fan and shroud out to get to the alt.as I'm starting to try to loosen the top adjusting bolt,I start to feel it is going to break.So stop,sprayed some PB Blaster on it ane gently tap it with small ball peen hammer to try to help break some of the oxidation that has occured over the past 25 years(it is original,I checked the no's b4 starting)after waiting about 15 min.I tried firm but steady pressure and a light to watch the front of the bolt to see if it was in fact turning, it just all of a sudden snapped :ugh .Oh well, Now I'm attempting (tomorrow) to drill it and remove it with an easy out.
One more thing to add to my to-do list b/4 spring...:eyerole

be careful with the easy out if that breaks you have real problems. you may want to heat it up a few times and melt some candle wax on it or penetrating oil it will be smokey but it helps wick the fluid up the threads best of luck Steve

I agree on the easy out comment!!!!!!! They usually don't work and when they snap you've got a real problem. Drilling it out carefully would be the safest method, use a center punch at the exact center of the bolt then carefully drill.

Good luck
