How hot is the

[BlueWaffle]

alternator supposed to get? i just noticed that mine is damn near nuclear hot. i spit on it and it just boiled right off. I'm sure its supposed to get hot but how hot?

That seams to be pretty hot, i would shoot it with a temp gun and find out for sure.

I would imagine anything over 200 would start hurting electronics but i dunno, my old 7.3 ran hot as *** too so maybe thats how it is, but that truck went thru 4 alternators in the time i owned it

 

[BlueWaffle]

i really never thought about it before but you can't keep your hand on it for more than a split second.

i acutally put a fire extinguisher in the cab before I went to run some errands LOL

What does your engine temp run at? If you're seeing engine temps in the low 200's then that thing could be just as hot...Oh, hell you're in Texas to boot!!

Time for a heat extractor in the hood?

The one in my 04 got like that so I had it rebuilt and it never got hot on me again. It was only $60 to get it rebuilt also so I definitely wouldn't buy a new one.

I didn't know they were rebuildable...where would you get that done?

any auto electric can do it. I just had the one on my 04 rebuilt for 35 bucks.

:whs:

I used to go to a guy in Batavia, il and he would rebuild starters and alternators for 45 bucks. I bought a new one and then had him rebuild the old one. The new one spun the motor over a lot faster than the rebuild. It did work though! Id imagine an alternator would be less critical.

Whatever you do don't but an Autozone/ Advance or any of the like alternator or starter as they are complete crap.

Mine get's too hot to touch too, but it's been over 100 deg. for 60 something days so pretty much anything under the hood is too hot to touch if the engine has been running for any length of time. For that matter, if I park in the sun with the engine off, the hood is too hot to touch too.

Get some actual temp readings to be sure you even need something done. I'll try and remember to shoot my alternator tomorrow and see what temps I get. When it's time for a rebuild, just google alternator and starter rebuild in your area and you should get some hits.

I'll try to remember to shoot my alternator tommorrow with my infrared thermometer.

 

[BlueWaffle]

yeah if you guys wouldn't mind getting a temp reading, that would be great!

 

[RocknRoll]

I can get you a good temp also. Headed to Hot Springs Arkansas tomorrow to meet some buddies rockcrawling/jeeping. When i stop for fuel i'll hit it with my infrared gun and post up!

Drove about 2 1/2hrs with a 15 minute stop at Wally World for oil and I was reading 185* when I hit it with my infrared. Just as a comparison, the idler pulley was also 185* and the ambient air temp was around 92*. BTW, spit did not boil off.

6.0 with the small case alternator are notorious for running hot
A good upgrade is going to a large case

I have actually had the best luck with there altenators and startors. after going thru multiple napa and auto value ones over the years I started using autozone ones.I have had great luck with multiple vehicles and there startors and altenators.. Those are two things I only buy from crapzone.

 

[Zmann]

I had to swap cases to a marine unit when I bought a new Autozone Duralast reman alt

the amount of old parts in the case was a joke

 

[yeehaw]

i sell plenty of napa ones and rarely warrenty one unless it is 10 years old (give or take)
