iam now on my 4th alt. in my 03 civic lx 4dr.. i have noticed that the alt is way to friken close to the exhust manifold.. and when i go on a road trip, like over 1000miles, i usually return with a burn out alt... is there something i can wrap around the manifold to shield the alt from the heat? or i am thinking of running a pipe from the bumper up to the alt and this will blow cold air across it.. just a thought.

the exhaust manifold should have a heat shield on it already. if it doesn't then you can get insulating manifold wrap from a parts store.

Do you have any aftermarket audio? Huge subs/amps etc? Those things can burn through alternators like nobody's business.

the exhaust manifold wouldn't cause the alternator to melt. i don't have a heat shield on my mani and i've never even had to change the alternator.

improper ventilation can cause worn bearings, one of the biggest causes of alternator failure besides charging system issues or worn belts.

having too much tension in the belt could also wear the bearings out.

This. I just had my alternator replaced due to shot bearings because whoever serviced my car from the previous owner tightened the belts way too much. I've got to get a new AC compressor as well because the bearings are shot on that as well.
