Denso 210-0657 Alternator

Alternator came in great condition, looked practically new. I installed it on a 2010 Lexus IS250. I found that zip tying upper wiring harness(at oil filler cap) and lower wire harness(Near coolant bottle) out of the way and removing electric radiator fans along with upper coolant hose and top end of lower coolant hose gave me the room needed. It was fairly easy until you get to that rear nut on the alternator bracket, I used a short extension and put a ratchet swivel adapter on the end next to the ratchet. This made it easier to get the head of the ratchet onto the socket with extension due to the limited room. Watch the Youtube videos and one should help with additional hints. Also replace your serpentine belt since your at it. I purchased a Gates brand from Oreilly's.

Alternator looks brand new despite being remanufactured, came in original Denso packaging. Best to buy the OEM Denso alternator instead of a cheaper no-name one for less.Works great right after install on 2008 IS250 AWD, will update review if it goes bad.Was able to install it myself following Youtube videos, all you need are 10, 12, 14 mm sockets, helps to have 3" and 6" socket extensions, a breaker bar to loosen tight bolts, flathead screwdriver, pliers, and deep sockets can be helpful too. Telescoping mirror and telescoping magnet from Dollarama can be useful to see the hidden bracket bolt and pick up any bolts you drop inside the engine bay.A lot of videos seem to get the old one out without taking off much else but I tried for hours and ended up needing to take out the black ECU housing box to the right of the alternator which some videos show. This gives you much more space to work and made getting the old one out and new one in much easier. Be careful not to damage the ECU or wiring.

Always go with OEM if budget allows. Fits like OEM. Replaced original alternator on 2006 IS 250 with almost 200k miles. Loved TOYOTA quality!

Working fine so far. No issue.

Oem altenator for less happy customers 👍
