Hi,

How do I know if my 89 3.0 has a 3G alt? or, is it possible to upgrade to them? are these 90 or 65?

same question for my 4.0L 96 Explorer?

Thanks,

Here are a couple sites that might help. The first one tells what a 3G alternator looks like. Both sites have conversion kits

I can't edit my post - there's also a sticky on the subject.

I may have to convert my Escort when I add my 50% under drive pulley

I had a set of underdrive pulleys on my 87 Mustang for a while, and I'm not sure they helped with anything. But they did cause low idle voltage, which usually left the battery weak, and low power steering assist, which made it difficult to make fast turns.
