I have a 1994 Path, 4x4, Auto that's suffering yet again. She's getting old with 258,000+ miles, and I'm suspecting that there's a bearing going out in something like the water pump, or alternator, or something...

I'm getting a whinny windy roaring noise under acceleration (anything over 20 mph) and a power loss. She's having trouble getting up to speed, and uphill is harsh on the ol gal. Considering I'm going on a 3,000 road trip over two mountian ranges while towing over 5,000 pounds in a mere matter of weeks here, I am a bit worried.

Do any of you all know what could be going on here?

Pick up a mechanic's stethescope and see if you can isolate the source of the noise.

If its a bearing up front on the engine, it should be relatively easy to pinpoint it with that tool.

If I had the time off work I would. But I don't. I think I'll have to drop this off at the dealership closest to work and see if they can help.

maybw your fan clutch froze up.

I'd ditto on the fan cluth if it sounds like a roaring noise of lots of air moving. I've had several fan clutches go out and this wind noise is the tell tale sign.

So I went out on break, checked the big white fan, and this thing doesn't turn well.

Turning it to the passenger side was sluggish. turning it to the drivers side, hit a hard spot, then was really hard to turn.

Shouldn't the thing move freely???

yep it should turn freely, you need a new fan clutch. no big deal at all.

I called up the local Nissan, and ordered one up. They said they had a bunch on hand since they're failing on all the older nissans, but they ran out a little while ago...
The earliest they can get it is Thursday morning. So I bumped my appointment out to noon on Thursday.

They fixed it yesterday!
