Alternator Bosch or Denso

I replaced the alternator on a 2013 XC60 T6, which was driven by a coupler. The Bosch unit had a drive pulley (not really a pulley) already attached.

Manual, buy a reman denso or used or new OEM off the eBay or other seller, harder to rebuild those in my experience.

Have never had to warranty out a denso alternator.

I bought a good-quality Bosch Reman alternator for my 2012 Mazda and it cost me $128+$75 core ($203) from RockAuto.

Denso and alternators from Toyota are the only ones we\u2019ll use for this exact reason.

Similar symptoms when my '05 factory alternator died. Get a jump then measure the voltage at the battery. If it's ~14VDC, the alternator is charging. If it is only ~12VDC replace the alternator.

I did the Alternator on my ES350 (same 2GRFE engine) and it sucked. It was my first major repair project and took almost all day for me.

I’d recommend DENSO reman as they make a bunch of OEM stuff for our cars. Recently put a denso in my car after I got the pure energy brand on rock auto that failed.

I bought an aftermarket bosch alternator, (new not refurbished) and after installing the pulley to 80NM (black part), I noticed a wobble and a brushing sound. The original alternator does not have this brushing sound.

Everything went well, or so we thought, as he turned on the car it started to slowly smoke. I assume that the ac compressor plug got shorted or was loosely plug bc it was the hardest thing to replug and the fact the ac isn’t blowing cold air anymore. We recharged the battery to 12.4-12.5 v. The alternator was only pulling 13.3-13.7 v with load and without load. Mind you this was a new OES Bosch alternator.
