Alternator AC DELCO or OEM Nissan

I purchased a 2002 Nissan Quest alternator for my 2002 Xterra. It bolts right up. 120 amps instead of 80 amps.

But its a Ford truck/suv and the alternators ALWAYS go bad on them. Word to the wise, buy an AC Delco replacement or Ford OEM, anything else will just die again-they always do.

I'm a little biased towards the Z32- Winter mode Summer wheels I love how it drives, feels and looks. ~80k miles since 2003 I've replaced the alternator a couple times, high pressure power steering hose, a couple injectors, the clutch twice and many tires.

I have 155k on my 2002 Nissan Frontier XE King Cab 4 cylinder 4x2. No real problems besides a bad alternator and rear e-brake cable that I just replaced

Bought a '91 XE 5 speed in 1996. Sold in 2000. Took it from about 60K to 150K. Pros: Gas Mileage--High 30s, never saw 40 like some people. 5 speed helped keep it peppy. Anvil like reliability. Replaced alternator and clutch.

Another good way to tell your alternator is going is the battery light illumination. I noticed as I drove to higher RPM's, used the vents or even used windows with more power gave more illumination of the battery light. Tested the alternator at a shop and found it to be weak, battery was fine.
