Hello everybody,

I have a 1994 Accord LX 4-door (2.2L, MT, A/C) that needs a new alternator. While shopping around I noticed that the EX Accords are equipped with a 90-amp alternator which is 10 amps better than the 80-amp units that the DX and LX models came with. I figure it would be wise to swap in the higher-capacity EX alternator in anticipation of an aftermarket stereo installation. The 90-amp unit is also a couple bucks cheaper. I just want to be sure that the alternators are interchangeable. Does anyone have any knowledge regarding this topic?

Here are some specific questions:
Are the alternators the same physical shape/size? Judging by pictures online, it looks like they are, but the pictures used by sellers online are often very generic and can sometimes be misleading.
Are the pulleys the same diameter? / Are the belts the same length? There seems to be just one belt size listed for all A/C-equipped 94-97 Accords, but I was hoping to get some reassurance from someone with direct experience.
Any differences in electrical connectors?

Thanks in advance!

 

I'm a fan of Denso remanufactured parts for Hondas. I've seen folks on here have issues with box chain rebuilt alternators. It is worth the price difference in my opinion.

Based on densoaftermarket.com, either 90 or 80 amp alternator will work on your car.

 

Cool, thanks. I was actually already planning on going with a Denso, since they made the original part. It's definitely reassuring to hear a testimonial.
I try to avoid generic/no-name parts when I can.

 

Parts have been ordered - 90A alternator and serpentine belt. I'll also grab a 100A battery fuse--as used in the EX--to replace the stock 80A fuse in my LX, per a suggestion on another forum.

I'll update when the parts are installed.

 

Finally got the last part installed yesterday and took the car on a test drive.

I actually got the alternator installed last weekend, but there were some setbacks that kept me from driving it until today. During reassembly, the tension adjusting bolt for the power steering belt broke, the radiator cap fell apart when I checked the coolant, and the first fuse I ordered was the wrong physical size. I had to order in the radiator cap and correct fuse and then got sidetracked overhauling a snowblower in preparation for some big accumulation Friday night. Saturday was snow removal day, and I finally got the last part - the radiator cap - put in Sunday evening.

It ran and drove great, despite the fact that the gas in the tank is at least 3 years old. I still have some other rehab to perform before the car is a daily again, but I'm off to a good start.

Thanks for the help.
