Denso alternator was like $350 and it took us like 3 hours as total novices and that includes the 3 trips we ended up taking to NAPA.
Did my own alternator, Denso 300.00. Took about an hour.
Alternators do like to go out on ISs. Burning smell and whining is the telltale signs of it going out.
Denso. Expensive but, my last one lasted 25 years lol.
DENSO remanufactured is solid.
Get Denso 2104148 that’s what I recently got. Works great!
I put a remanufactured Autozone on mine in a pinch because that’s all the was available. Never trusted it. Replaced it about a year later with the Denso remanufactured for peace of mind.… when I took the autozone one off the bearing was squeaking pretty bad. Denso has given me zero problems, going on about 4 years.
The next best thing for Honda is DENSO as they are the actual OEM supplier. 90% chance ur old alternator says DENSO on the side (as long as it's the original).
Just make sure to buy either new OEM, used OEM, or a good rebuild like Denso. Parts store ones have a bad record of either being bad directly out of the box, or crapping out in short order.
I've gone through three Denso alternators in the last 4 years! This last one went almost two years before going out.
