NAPA Alternator

[rbrave]

My parts store alternator just but the dust today, after hanging in there for quite a while with an annoying whine and getting PS fluid dripped on it slowly. While I’m in there fixing both issues, I’m looking at prices for rebuilt DENSO and similar alternators and seeing that NAPA has a line of “new build” alternators (not rebuilt, but brand new).

Any sense in this over other options? I have been consistently sticking with OEM for everything, but alternators aren’t really possible to do that with. If prices were the same for a rebuilt denso vs the “new” NAPA version, which one are you buying?

Looks interesting with a lifetime warranty.

That’s only 80 amps.
Check rockauto for a Denso alternator.

Is stock 100 amps?

100-130 depending on year AFAIK.

Odd they would list an 80 amp alt as stock for a ‘98? Partsgeek has the same OE manufacturer (WAI) listed for 99-2002 at 100A, with a better price.

I like Toyota Denso remains. Second Denso remans. Difference is, Toyota requires certain parts be replaced. Other is up to rebuilder on what parts are needed.

Note: Two different alternators in 100 series. 98-02 and 03-07.

Wire housing blocks, have a 5 digit part number (suffix) on them. Add the prefix 90980-*****. If my notes correct 98-02 alternator wire housing block is P/N 90980-11349. But, best that you make sure, to check your wire housing for P/N suffix.

I simple wipe clean wire housing and take pictures. Then check pictures for P/N. Pictures will also be useful, to see each wire position. In most cases, I remove one wire at a time, and place it in new wire housing block.

I find it easiest. To use small curved needle nose pliers. Breakaway small pieces of old wire housing block. Being very carful...

7 out of 10 alternators, I see fail. Don't have the #1 undershield (skid). Our alternators, are surprisingly susceptible to water damaged.

98-99 originally came with 80A alternators. But the OEM superseded part number today is a 100A alternator. 00-02 were 100A. If you order the NAPA 2000 alternator, it shows as 100A.

Last summer I replaced my failing part store alternator with Denso Reman 130 amp part #210-1099 for the later year LCs. Necessitated a pigtail swap. Extra mounting point did not interfere. Info here.

Ordered parts to do this last night, will bang it out over the weekend. Thanks for pointing to that thread!

Well, after getting the old alternator pulled, all of my seeping power steering hoses replaced, and my engine bay cleaned up - I discovered that the reman DENSO that I was sent was incorrect. It was 100A and basically everything but the stud mounting location and 4-pin connector was wrong. On Memorial Day.

I ended up calling my local NAPA, who didn’t have any replacements for any year Landcruiser but DID have a 130A that was intended for a Sequoia. 20 minutes later I had it in my engine bay, and 130A at that. On a rig without any aux equipment (for now).

For those coming here later - just take an alternator replacement as an opportunity for a radiator drain and fill. Removing the top side radiator hose saves a bunch of hassle with the fan shroud, and it is a heck of a lot less work to go with gravity than against it. Unbolting the PS pump is simple enough, and in the end it was a lot faster to refill the radiator than mess around under the truck trying to find the perfect position. Having two sets of hands helps as well!

The 130amp Sequoai is a perfect fit with no mod to
the wiring or whatever?

No, it requires a four pin plug. My three pin plug shattered on removal, so this was realistically the same amount of work. The four pin plugs with pigtails are available on Amazon and other places, but I would have preferred to buy an OE housing to repin. I believe that would be 90980-11964. The Amazon one had slightly different pins that didn’t work directly as an OE swap, hence my splicing in a pigtail.
