When i got back in car the battery indicator light was on the heat is not working the squeal is gone then the temp guage went way up like it was going to over heat.....

Your alternator belt broke. That causes the battery light to come on because the battery is no longer charging, and it causes the car to overheat because the water pump isn't working. That's where it gets dicey. I replaced the alternator and belt. The new belt squealed a couple of days and then broke. Replaced the belt, new belt squealed and broke next day. Mechanic is trying to isolate current problem now. I've been looking at other sources who suggest checking the pulleys, tensioners, and water pump. Good luck from here.

How to replace alternator belt on an 03 spectra

Look at the alt. On top you should see a "t" shaped bolt system 1 is facing the wheel well the other facing twords the firewall. Loosen the one facing the wheel well first. then you will see an other bolt on the bottom of the alt facing the wheel well loosen that one up. after those 2 are loosened go back to the bolt facing the firewall and loosen that you will see the alt will be able to slide twords the engine and give you enough slack to remove the belt.

2003 kia spectra, 5 speed, had the belt replaced, now it squeals worse

I believe I know the noise that is troubling you. If a new belt is correctly tensioned and still makes such a noise it would indicate either contamination with oil or similar or pulleys that are less than perfectly aligned

The noise and your description is symptomatic of slippage and the pulley that is most likely to be slipping is the small alternator pulley. After starting and when accessories are being used that require a significant current the alternator needs considerable power to drive it in order to produce that current/replace the battery power used to start the engine.

The increased power to drive the alternator must be delivered via the drive belt. As the battery voltage rises the charge rate will fall and the power needed to drive the alternator falls and so the squealing reduces and then stops.

One further thing to note is an engine and it's ancillaries expand or grow quite a lot in engineering terms as it warms up, this has a tendency to tighten the drive belts further.

Check belt tensioner adjustment. Spray WD 40 on belts and pulleys and start. If no fix .it is most likely the rear bearings on the alt. before you buy a new one shoot some WD in the rear of the alt through the slits to the shaft. No fix take it to your local chain parts store and they will check it for free.
