Check charging system!! 2000 ls v8

(Click here to view the original thread with full colors/images)

Posted by: jaysar27

problem. charging system light comes on, then I rev up the engine a little or give it gas, and it goes away until i come to a stop or slow down. My car just died because of of dead battery. I took the battery to have it checked and it was good. I figure it must be the alternator? Is there anything else I should check before I go buy an alternator?

Also, does anyone have any tips or diagrams on how to change the 2000 lincoln ls v8 alternator?

thanks in advance.

wow! thank you for the information and quick response. Time to get started. wish me luck!

thanks again

well i got the alt. out, finally. That was a pain. Well not that bad, just so much oil. It was caked my alternator. Is it possible if I clean it up with some electrical cleaner, that it might work. Never mind, I will just go buy one.

Also, I noticed alot of build up (oil, I think) coming from above the alt. but I can't seem to find it when im looking from the top. Any ideas?

One last thing, my power steering res. and my fan clutch res. are pink!

It looks like strawberry milk. I have no idea why this is happening. Is there anything else I should check or replace while my engine is almost stripped?

thanks

You are a better DIY than me. I was able to get the bolts out, but mine would NOT budge last year. Even drove it a few miles to the dealer with NO bolts..and it was still tight.

$228 later, they got it out, and put in the Palladium (motorcraft rebuild) that I obtained from AutoZone or Advance.

That one failed 2 weeks ago..10 months after the install.

Lifetime replacement..but you have to bring in the old one for them to give you another.

I opted to not go back that route. Took it to Pep Boys who charged $78 to remove it, and replace it with a $150 Duralast rebuild. Yes, rolling the dice again with a rebuild vs simply forking over 125% more for a new Motorcraft or Bosch unit.

If it lasts me 2-3 more years..I'll be fine.

Hmmm...mine is a V6, not a V8, but I know that the V8's are prone to valve cover oil leaks. Perhaps yours is leaking and getting blown around the front of the motor. Is the oil level ever low when you go to change the oil, like it is losing a fair amount?

Posted by: jaysar27

Just got back from the getting rebuilt alt. I think I found the oil leak exactly where you stated. My valve cover bolts are a loose. Can anyone tell me what I should torque them to? I don't have a manual. I can't seem to find one anywhere at the local auto shops, so I will probably have to fork out the money soon and go buy one at the dealer. If anyone knows where I can get a cheaper one, that would be great. Or where I can get the specs from? I will have to wait to put the alt. in because there is know way I want to take it out again. So any info would be great. Also, my lincoln has 181,000. I have had to

replace the battery
alternator
coils, a couple of them twice
transmission, some bearing or seal had to be replaced 800 bucks
oil, of course
plugs
brakes, ect. ect.

thats pretty much it.

But, I still don't know why my power steering reservoir and fan cluth res. looks like stawberry milk.

thanks again

Torque em till you round the heads off. Torque wrenches are for little girls!

I don't have an answer for you, I am sure that one of the gurus here will. I have a sneaking supicion that it might not be as easy as just tightening them down. You might be in for a gasket change. Obviously just try tightening them first, but if that doesn't solve it, things get a little uglier.

Not sure about the stawberry milk, it sounds like water got into the resivour and got churned up...

If the PS fluid looks like milk its probably long past time to change it. Might want to take that in for a flush. Also check the hoses on the fan reservoir for leaks. That sits right over top of the alternator, I would suspect that first and foremost.

I got the alternator in, finally. Thanks everyone for the help. It was running fine for a couple of days, and then, all of the sudden my abs tractions system starts beeping and flashing on and off. Then my charging system light comes on again and poof.... my batteries dead once again. Same problem. I don't know what it might be. But this time by abs traction system did not stop blinking or beeping.

Maybe I could of have gotten a bad alternator? It was refurbished from autozone. Any ideas?

I guess I will start taking out the alternator again. Not fun.
Thanks again

Posted by: lseguy

wait..you didnt check the previous alternator with a voltmeter first?

Posted by: jaysar27

nope. stupid me. Im kinda new to this diy stuff. so any help would be appreciated. how do i test it with a volt meter?

Could it be my water pump pulley? If the water pump is bad? Belt? Im stumped.

thanks

Yeah that's the problem...

No, im kiddin. Check the connections on the battery. Make sure the posts are nice and clean, no corrosion.

To test the alternator output voltage, first off you need a voltmeter. If you dont have one, buy one. They're useful when it comes to this DIY stuff. You put the positive lead from the VOM on the positive terminal of the battery, negative lead on the negative terminal. If it reads less than 12v with the engine running, the alternator is bad.
Now next time you have a charging system problem, take the alternator in and have it TESTED before you buy a new one.
Another tip: NEVER BUY REMANUFACTURED ALTERNATORS!!!! They suck, bottom line. I put 3 in my Cadillac in a 2 year span because I was too cheap to buy a new AC Delco unit. Spend the extra money, once youre sure the alternator is the problem and buy a real Original Equipment alternator. In this case it would be Motorcraft.

My Charging System Light Comes On Also So Its Not That Battery?

Posted by: chickenviii

take that autozone alt and throw it at the wall!!! you should get around 14 volts at the battery when running, your abs/trac light is on cuz the abs computer sees low voltage and most important never NEVER go to autozone!!!!!!!!!

Posted by: jaysar27

Yep, confirmed! They gave me a bad alternator. It failed!

And then the guy says, this looks like the original.

LIke I was trying to scam him or something. I just about threw that thing at him. Anyways, here we go again. When this one goes out, I guess I have to go to the dealer. Unless anyone has some suggestions where I can get one for a good price.

Also, can someone please give me the specs and diagrams on how to flush my fan clutch reservoir and power steering. I would appreciate it. Thanks to everyone for the replies.

Thanks again
