1992 Chrysler Le Baron • 4 cylinder FWD Automatic • 84,000 miles

I have a 1992 Chrysler Labaron 4 cylinder sedan when the engine warms up one of the belts start squealing. The arrow on the voltage gauge on the dash moves to the middle of the gauge when this happens. What should I do? Also my oil pressure gauge reads high when the engine warms up but the arrow goes back to the middle whats up?

Check the belts to see if they are loose and adjust as necessary. As for the oil gage issue, verify that the oil level is correct. If it is then replace oil pressure sending unit.

First, where does the voltage gauge start out at before you hear the noise? As far as the oil pressure gauge, chances are the oil sending unit is bad.

If the volt gauge is low and goes up when you hear the squeal, the belt is loose and finally catching up with the alternator. Also, make sure that it isn't covered in oil, coolant. THe oil sending unit is a cheap and easy part to replace.

Check that and let me know what you find.
