Rusted Bolts

[mbjj]

I bought a friends 92 Legacy that he was proud to say never saw
any maintenance. It shows...I'm trying to catch up and I noticed
where all/most of the bolts are rusty. In the process of taking
out the radiator/fan assembly I managed to break off 2 bolts.
These things broke with ease. I want to examine the timing belt
and I'm coming across the same situation. Once I get the 10mm box
end wrench [I'm not using power or sockets on these and it takes
a little doing to get the box end on] they break loose kind of
easy. About a third of the way out they get tight and then just
break. I have visions of angle drills and easy outs drilling into
the motor and I'd really like to avoid that. How can I get these
things out without shearing them off. I'm spraying them pretty
good with a penetrating oil [PB Blaster] which is non water
based. Any ideas?

One way that I have seen this done is to get in there with a welder and weld
a nut onto the exposed end. Sometimes even a short pipe nipple over the end
and weld it in. Then you have a pipe to grip on. Another is a stud
puller.Sears has a new set of easy outs that are supposed to work on rounded
bolt heads. Maybe you could get a small on the broken bolt end.

Next time maybe hose the bolts down with some WD-40 or similar solvent. Then
hit the end of the bolt with a hammer a few times. Then spray a little more,
wait a while, and then start turning it out. Stop, turn it in, then turn it
out. repeat nice a easy till its out.

Good luck...

BLAST-IT is a very good rust solvent for this job. Any large auto parts
store. It's in a spray can. eddie
