I did a search and found a few posts on changing the alternator so don't write me off as a newbie. I still can't find any good directions or pics. I've done a lot of work on my '91 240sx, but this is the first time I've worked on an alternator. I have 225,000 miles on my stock KA24DE engine and I believe that this is the original alternator too. It finally died and took my Sears Die Hard battery with it. I've purchased a reman Nissan alternator from a parts store. By the way, I've been driving for the past week on a $30 battery from Wal Mart!!

So now I've gotten all 3 wires off. I removed the throttle body so I could reach the top bolt.

The top bolt has another long bolt crossing it. Is this the tension bolt?

I've loosened it as much as I could but the radiator hose is in the way so it took all afternoon to get it loose. The bolt is really loose now. Do I need to take it all the way off or will the alternator come out when I loosen the bottom bolt? The belt is still tight. The bottom bolt is stuck solid so I sprayed it with WD40 and I'll leave it until tomorrow. I think I'm almost done. Thanks.

all you had to do was take off the 2 bolts on the alt, take the 4 bolts off the sway bay and let it drop down, move the radiator hose the side (without taking it lose), and drop your alt down. reverse the directions for the reinstall. its kind of a pain in the *** no matter how you go about it.

Thanks Tears. You are right on the money. I dropped the sway bar and pulled the alternator out. I got the new one in OK, but I couldn't line up the bottom bolt. I got the belt as tight as I could and drove it to my mechanic's shop where he checked my work and got the bottom bolt in. I'm back in the saddle again.

So have you done a cold air intake? Nice icon by the way
