ACDelco 8-2201 fit my 85 without any problems.
I had the AC Delco alternator (an OEM part) in my 1994 Saturn SL2 rebuilt in 2015 by Alternator & Starter Co. At the time, no new OEM or aftermarket alternators were available for a Saturn that old, and the guru who advised me on Saturn repairs told me I would have better luck with a local rebuild rather than a commercially remanufactured replacement.
I'm showing a new acdelco 135amp alternator for roughly $163 plus shipping through rockauto.
Acdelco is oem for GM. They make high-quality parts, never been disappointed by one.
ACDelco makes a brand new alternator for $95. They were the OEM for GM.
I went with RockAuto as well, but went with the AC Delco Gold Reman that was wound to have 135 Amp output instead of the OEM standard (~110 I think) I want to say it was around ~$170 with a $45 core deposit. AC Delco is a solid name in parts, and I believe was reman'd in Mexico.
Use the AC Delco iridium original plugs. Many sites will only show the double platinum as a replacement but every time I've ever driven an engine with those in it, it pinged or idled rough and iridiums always fixed it.
For anyone having this issue with a 454 7.4L Big Block Chevy Starter; PLEASE get a NEW ACDELCO starter with brand new knurled bolts from NAPA. I’ve had this side for months where my starter pinion would get stuck to my flywheel and grind till my flywheel shaved.
ACDelco DexosD. 0w20 is practically water, but GM says to use it in the 3.0L Duramax and until the warranty is up, there's no reason to change varieties.
Man do yourself a favour and get either amaron or solite. Both lasted me almost 3 years. You're lucky that AC delco lasted you almost 2 years, the ones I get barely lasts a year, and that's with warranty replacement .
I’m on my 3rd battery since Nov 2021. Every time it has lasted me 1 year and 3-4 months. Not even 2 years.
I don’t have a parasitic drain. I don’t use AC a lot. I don’t jumpstart cars with it. There is no excessive load on it. Yet, they all lasted less than 2 years.
