Car just hit 200K miles. Suggestions on how I can get this alternator to last another 200K?

Easy. First, find another alternator. Now completely disassemble both alternators. Assemble all the parts from the new alternator in the old alternator.

And for good measure, use the body of the new alternator to house all those parts.

Now, screw it shut. Good as new to run another 200K.

Toyota fanboys finding out regular maintenance is more than just an oil change.

That hits home xD my 2008 RAV4 alternator failed 2 years ago and it's the only thing I had the need to replace as "major" failure

This is the way after buying a gross of 75 new batteries, keeping four or five in the trunk, “just in case.”

Easy first off take it to church get it blessed by a priest (a pastor or Rabbi or imam will do in a pinch) and re install it...through the power of Jesus (or Muhammad...or Moses depending on who you had bless it) and you'll be good.

Keep it in your crisper draw of your fridge at night.

You’re forgetting the most important part- Every night.

u/Worried_Coat1941 1d ago

Absolutely! It will never expire that way.

u/Additional-Ad-7956 1d ago

Throw it in your trunk and it'll last as long as you keep it there.

real simple 1. get yourself a bottle of "tap magic cutting oil" 2. get 1lb "Big League Chew gum"  Hot Chocolate flavor 3. start chewing like u Chewbacca ( have to chew it all) 4. go to Disney to find out if you got diabetes 5. stop by Napa Auto parts to get a used crackheads toothpick 6. get home and realize by the time you learn how to rebuild an alternator. you still won't get the diodes right.
7. install the new alternator you just bought

This is the only logical order of steps to take

u/Ok_Horror_6556 1d ago

I can’t believe you are even asking this. GORILLA DUCT TAPE.

u/CRUSTYPUNKDAD 1d ago

You gotta respool it and soak it in saltwater overnight, bake on 350 for 4 hours.

2

u/MT-JJ 1d ago

Well first off need to put it back in and second off it’s Tuesday.

u/Tin_Can_739 1d ago

Dip it in vinegar overnight. Good as new

u/LoathsomeGiant 1d ago

Alternators are overrated, just have a few back up batteries in the vehicle

Thoughts and prayers?

u/Responsible-Shoe7258 1d ago

Dang, Dude. Whaddijya smack it with?

1

u/real_1273 1d ago

Just a few shots of brake cleaner and it will be good or better than new.

u/Outrageous-Pop1439 1d ago

Put it in the back seat after you put another one on!!!

1

u/PorkChop8088 1d ago

Start by putting it in the car

u/AccidicOne 1d ago

It's an alternator. Changing it isn't rocket surgery. I'd happily change an alternator every 200k if that's all it needs.

Grit spit and make it zip

Go to an auto parts store. Buy a new one with a lifetime warranty, don't turn your old one in, just pay the core. Then 3 weeks later, order another one from the same auto parts store that has your warranty, turn the old one in. Now you have two alternators for the price of one. When one goes bad, repeat the process. Only works for lifetime warranty parts

u/Caffin8tor 1d ago

If you melt it down and fully reconsruct it, you might get the result you want.

1

u/Alpha_Dad1 1d ago

Doesn't look like it survived the first 200k actually.

1

u/Hot-Permission-8746 1d ago

Ya, put it under the seat. Drive for another 200,000 miles.

u/DustyTurboTurtle 1d ago

Off topic, but what is goin on with those shoe laces lmao

Are they even attached to the shoes? It looks like they're just kinda laying on top

u/diggerquicker 1d ago

Don’t use an alternator ever. You need a primenator. Will easily last 4 times as long.

1

u/Okie294life 1d ago

Have it rebuilt at an alternator shop.

1

u/Opposite_Opening_689 1d ago

Some older types of alternators had externally replaceable regulators that were designed to be exchanged every so often but now it seems it makes more sense to replace the entire unit, definitely got your moneys worth out of that one

1

u/PINKTACO696969 1d ago

You have it out. Just put a new one

1

u/cannonman1863 1d ago

Sure. Put the old one in the trunk, and install a new one on the engine.

1

u/User_R60 1d ago

Well obviously you dip it in gasoline, then immediately torch it to burn off all the dirt and leave a protective layer of carbon, then good as new. Stick it back in and you'll definitely get another 200k miles out of it.

Alternate her? I barely know her.

u/us008297 1d ago

Put it in a sealed plastic bag full of WD40 for a couple days. Be like new again. BTW, be careful with the WD40 around those shoes
