The Random E46/ZHP Question Thread

[t.er]

What type of alternator does the Zhp have?
I’m seeing 90 vs. 120 amp and 2 pin vs. 3 pin on fcp and it says they all fit.

I think an easy way to check was whether it had a duct or not. Mine didn't and had the rounder plug.

FWIW try swapping just the voltage regulator first, seems to have done me and a bunch of e46f guys the trick rather than replacing the whole thing

Looks like they came with both:
Exch. compact alternator90A12317501687
Exch. compact alternator120A VALEO 12317501599 ENDED
Exch. compact alternator120A BOSCH 12317501690

Thanks John.
Some folks seemed to have bad experience with Bosch alternators, especially remanufactured ones. Maybe Valeo is the way to go.

Ah my car doesn’t have the duct either.
I’ve thought of replacing just the voltage regulator but at 215k miles and nearly 18 years old, I’m thinking might as well.

Yeah, Bosch has gone downhill over the past decade - I'd imagine a Bosch rebuild might be iffy, but should come with a warranty. See if you can get your eyes on the plug - maybe that will solve the mystery.

Have a buddy who works for Bosch in Germany and he says all they do is cut costs all day. I made the mistake of buying a Bosch coil that ended up lasting 3 WEEKS. Replaced it with an actual quality part and haven't had issues since. I would avoid Bosch at all costs.

I've replaced my 90v with a 120v remanufactured Duralast alternator. It was less expensive than the 90v with lifetime warranty. It's been a year with no issues.

Maybe this place, Maniac Electric Motors, has applicable parts (link). I don't have experience with them, but might try one of their rebuild kits.

Is Rein a good option for power steering hoses?
