I have a choice between 2 alternators for my Ef.

The original one sized up from sitting for about a month. I had to use an impact wrench on the shaft to get it to move. I soaked both ends in Liquid Wrench (~Pb Blaster) and kept spining it with the impact ~ 2000 rpm. It now spins perfectly freely, better than my spare, however it vibrates a little.

My other choice is my spare alternator, came off an EF, its in working condition, however, the pulley is a 3 groove serpentine and my crank pulley is a 2 groove, so the belt wont fit properly and risks geting eaten up (I assume if it moves along the groves of the alt). I tried swapping the pulleys, but the spare has a larger drive shaft and doesnt fit the 2 groove pulleys.

Which one should I take a risk on :D...its my winter car so it needs to be reliable.

 

how about bringing the siezed one to an alternator shop and have them change the bearings probably cost like $50 at most

 

Allready priced that out, 75$ CAD in parts.

I havent discounted that idea, but would rather have a cheap fix.

 

I would use the one that vibrates a little, maybe It will go away with use...
