I changed the alternator on my 99 alero an now it makes a loud sweeking niose is there a way to tighten the belt


LOOSE BELT MORE LIKELY YOU HAVE A BAD BELT TENSIONER.A BAD BELT TENSIONER WILL CAUSE BELT TO SLIP.WHEN THAT HAPPENS ALTERNATOR CANT SPIN FAST ENOUGH TO KEEP BATTERY CHARGE.AND IF YOUR WATER PUMP DONT SPIN FAST ENOUGH ENGINE WILL OVERHEAT AND YOU WILL HAVE POWER STEERING PROBLEMS ALSO HAVE DRIVE BELT TENSIONER CHECK OUT AT A GARAGE..

My Alero 1999, overheats, i change the water pump.. sensor.. relay.. and fans only work when i turn on the AC .


The problem is the coolant tempature sensor the computor.Not familiar with your model , but the sensor is useally lacated close to the thermostat..Most are a single wire. If you touch that wire to electric ground ,the fans should come on with the key in the on position.If it has 2 wires cross the termanial in the connection and they should come on.You have 2 sensors on the coolant system. 1conrols the gauge/light on the dash and the other is for the cooling fans

Why my 1999 oldsmobile alero runnig hot after I've gotten it fix


there may be air trapped in the coolant system. the fans may not be connected since you had the radiator replaced. bring it back to the mechanic who did the work and tell him your not satisfied.he should be responsible for the discrepany.

MY 98 DODGE 1500 360 OVERHEATS. I CHANGED THE WATER PUMP,CLUTCH FAN, THERMSTAT,AND NEW ANTIFREEZE. WHAT ELSE COULD IT BE?


Likely culprit could be a clogged radiator, as you did not indicate you changed along with the other items.
