any tips on getting the top alternator bolt out? It is frozen on to the alternator and won't come out. don't want to break it. i doused it with liquid wrench...

 

In order to get that liquid wrench down into the threads you are going to have to heat up the head of the bolt. Once the bolt is hot, the threads will accept the lube.

 

wait a while for the gear to get in then try tightening it first to crack the rust seal and/or give the bolt head a couple of taps with a hammer.

make sure you have the right size wrench for a good fit so you dont strip the head of the bolt


if that fails lean on it harder...remember "if it jams, force it. If it breaks, it needed replacing anyway."

 

Go get a 1/2 in drive breaker bar, on of the best investments you can make tool wise if you work on cars imo

 

PB Blaster and Map Gas FTW...... Has worked on every bolt I have had a problem with so far. Even the rusted on exhaust manifold and manifold to exhast bolts....

 

some times you have to break or cut the bolts to get them out its fun good luck with it

 

Isn't that the truth. I have used my breaker bar on countless occasions.

 

Yeah, can't tell you how many times i've used a breaker bar....or even stuck some pipe on the end for some MANLY leverage.
But +1 on giving her a love tap with the hammer, and the heat trick; both usually work well. When heating be sure to only heat the bolt so only the bolt expands, other wise your not helping yourself any.

 

I just used the saws all and cut it out. needed a new alternator anyway... on to the next one. new post

 

Sometimes the different metals will cause them to seize. An aluminum alternator housing and a steel bolt can corrode together. Try some heat from a torch around the housing near the bolt it works for us at our shop. Caution: Aluminum can't be heated like steel without melting it so be careful.
