So after I changed my radiator to an aluminum radiator, about 1 week after, during warm ups, the car squeals.

I have a video that I will upload as soon as I get home.

More background info:
1. The sound only happens during warm ups and dies out after the car drops below the 1000 rpm.
2. It seems to be coming from the bottom of the fan/ belt area.
3. It does not effect the drive of the vehicle afterwards.
4. It almost sounds like a rubbing, like something is touching the fan. But I rotate the fan when the engine is cold and its not hitting anything.
5. Car seems to be eating a little more gas than usual (i may be paranoid)
6. I see no coolant leak after radiator change.

As soon as i have more info, I will post it.
Some people are telling me it might be the start of a bad water pump.

THANK YOU

 

Its probably a bad belt rubbing. Replace the belt with a new one. Even if that isn't it it can't hurt to replace something with something new.

 

I had the belts replaced not too long ago. Like honestly less than 200 miles

 

Are they even a tiny bit loose? It'll also do it if they are really wet

 

Doesn't matter,if the belts decide to slip, they will,and that noise will be a sign that they are slipping.
If the belt Glazes from slipping it will continue to slip and then heat up and snap...Bye,bye new belt.

I used a sandpaper "sponge" and took all my belts off and cleaned the pulleys.
It stopped it.Try that.

 

I dont believe they are wet, didn't get any Radiator fluid on them when changing the radiator.

I will try this, what is this "sandpaper 'sponge'" you speak of?
And which belt did you take off? All three?

 

this is my video of the sounds it is producing.. the more and more i look at it and think about it, its probably a slip in the pulley

 

Sandpaper sponge is a Sponge that has sandpaper on it.
It forms to the Contours of the Thing you are sanding.
You can just get a piece of sandpaper and use it..no big deal.

 

will do, what grit should i be looking at? i have some 400 on hand right now.

 

..just enough to buff the crud out of the grooves.
Did you happen to check your belts and see if the V side is shiny?That is a sign of glazing belts(slipping).

 

Does the clutch fan still spin/slip freely? I've had one seize up. Maybe just loose belts, you can try that belt dressing crap as well.

 

will do this as soon as possible!

Edit: the v side did not seem shiny, it seemed dry

and the fan seems to be working fine, i rev the throttle and it catches faster and slows down on the release.

I applied some pressure on the belts as well, doesn't give, seems pretty tight

it doesn't seem to be running out of place either, but i will double check everything

 

Check idler puller bearings. Sometimes they get quiet after they warm up a little bit. Take the belt off and spin the idler pulley and check for noise or play. Doesn't sound so much like a slipping belt IMHO.
