Power Steering Pumps Leaks - Alternator Will Fail - How Long?

Anyway - same old story - power steering pump leaks - alternator is below the PS pump - I was wondering what is the time frame that once the power steering pump starts leaking is the usual or average time the alternator will fail. Also curious - how does the power steering pump fluid damage the alternator? corrosion? or? My power steering pump in my 1998 LS400 just started leaking last week. I know I need to address it ASAP - just going to be this weekend before I can.

it just ruined your alternator while you were making this post... there, do you feel any better, or worse?

both of these items were made by man, so they dont come with a time table,

but since others have warned you, you know what to do...

I guess you have figured out by now I am retired and really just dont have anything to do so I am answering your post which is about as important as my answer...

anyway, you are knowledgeable about it all and I hope you get it fixed without and further damage..

cheers, and good luck

smiles..

ps: how does any liquid cause failure to electrical items? you got it..

Texas eh? (license plate) what part of Texas? We lived in Georgetown - really enjoyed living there. I remember how upon first moving there form SC - first -- we were considered intruders ..not being native Texans -- second - thankfully we were not from the north side of the Mason Dixon Line and were generally accepted as long as we knew our place.. more or less. I loved Texas ... as I told people... It IS a whole another country.

you sure it is the pump and not the o ring under the reservoir?

the o ring cost like $1 takes maybe 10-15 minutes to change

I put in a small amount of UV light leak detector stuff this morning - I will check it this afternoon - the location of the leak will show up with the UV light.

The leaking power steering oil damages the slip rings and the brushes most. These have a rubber cap and the oil from above does not go into them directly and quickly but it does go in little by little and ruins them in a month or so because the airflow is there from backside to front side.

At the early stage, the resistance between the slip rings and the brushes increases and the out put voltage becomes a bit lower. You can save the alternator cleaning the inside at this stage. But if you let it go, the voltage is getting lower and lower and finally the alternator is dead and stops the function. I have seen some of those dead alternators and found that the slip rings were deteriorated.
