Car Forum / Honda Cars / August 2007Alternators
How long (in terms of mileage) does an alternator last? I have a 1998 Honda Civic EX sedan. It's generally the alternator brushes, and not the whole alternator say, that are most likely to fail at this point, assuming the alternator has not had anything else go wrong. See http://home.earthlink.net/~honda.lioness/id13.html for more discussion, reflecting a fair amount of what's been posted here in the past. > How long (in terms of mileage) does an alternator last? > > I have a 1998 Honda Civic EX sedan. Failure on my 98 civic LX occured at 178000kms (110000mi). Failure mode was the bearings. They failed, which allowed the center shaft to shift. This caused to rotor to dig into the copper stator assembly, making a rebuild less than economical. I actually replaced it with an alternator from the wrecker. $95 for a unit with only 118000kms (73000mi) on it. t >It's generally the alternator brushes, and not the whole >alternator say, that are most likely to fail at this point, [quoted text clipped - 7 lines] >> >> I have a 1998 Honda Civic EX sedan. > Failure on my 98 civic LX occured at 178000kms (110000mi).

Only upon disassembly did I discover that the stator was beyond repair... t >> Failure on my 98 civic LX occured at 178000kms (110000mi). Failure mode was >> the bearings.

Only upon disassembly did I > discover that the stator was beyond repair... maybe next time your car tries to tell you something you should listen to it, putting new bearings in the alternator is fairly easy and costs less than a whole new alternator. By the time the noise was noticeable it was too late. The whine was the stator being eaten away. >> at the time, $35 US was about $95 canadian.... lol >> [quoted text clipped - 5 lines] >it, putting new bearings in the alternator is fairly easy and costs less >than a whole new alternator. > It's generally the alternator brushes, and not the whole alternator say, > that are most likely to fail at this point, assuming the alternator has [quoted text clipped - 3 lines] > discussion, reflecting a fair amount of what's been posted here in the > past. I second that, and will even hazard a number: 150K miles is a rough life expectancy for alternator brushes. I've seen them go beyond 200K miles, but 150K miles or 200K km is a ballpark figure. 100K miles or 150K km is premature IMO. For the rest of the alternator I think most last the life of the car (but not all do by any means.) Aftermarket alternators are a whole different thing, too. >> How long (in terms of mileage) does an alternator last? >> >> I have a 1998 Honda Civic EX sedan. > How long (in terms of mileage) does an alternator last? > > I have a 1998 Honda Civic EX sedan. 100-150k, depending on use. on some makes [denso], you can replace brushes as a cheapo life extension. on others [mitsubishi], you can't and your only option is replacement. unless you're into recreational alternator repair, just get a reconditioned unit from a reputable source that offers decent warranties. >How long (in terms of mileage) does an alternator last? > >I have a 1998 Honda Civic EX sedan. Here is my experience with Honda alternators: '74 Civic 70K sold with original alternator still operational. '80 Accord 85K sold with original alternator still operational. '86 Integra 115K sold with original alternator still operational. '94 Integra GS-R 161K still running on original alternator '98 Odyssey 85K still running on original alternator In 33 years of Honda ownership I have never replaced an alternator. YMMV.

I would say more often than not that the battery and alternator are replaced at the same time. >im wondering if a battery thats getting weaker can strain the alternator and >cause it to go bad.
