My 1990 oldsmobile regency temp light keep coming on

This 3.8 V 6 is at back engine under alternator ,remove alternator to easy get there,is hard to put back with alternator on.

Un bolt it pull it out. Most likely it will be a bad magnet on the cam sprocket. Over time they will fall apart. The timing cover will need to come off to repair along with the cam gear.

i would recommend one with a 650 -750 cold cranking amps, and i would check for these at walmart. or auto part stores.

The air conditioning refrigerant/freon used in Oldsmobile regency is R11 (no longer readily available) so this can be used R134A. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Check the crank position sensor.(CKP) just dont go replacing parts, check them and verfiy bad.

if you are not experienced mech. maybe you should take it to one

Well the fact that the traction light came on and blinked off when taking off is a good thing, it just means that your traction control is working properly. When that light comes on it means that one wheel was spinning and that the car adjusted the speed of the drive wheels to compensate. The car not starting needs to be addressed as to whether the car is turning over slowly, clicking, or making no noise at all. The check engine light will remain on until the vehicle is started, so that does not correlate to your problem. If it clicks, or turns over sluggishly, then it just needs a jump start and a test of the battery. If the lights come on, but the car does not turn over al all, then you may need to look at replacing a starter.

Have free scan for codes done at Autozone or Pep Boys, and go from there. Eliminates guess work & unnecessary parts replaced.

i had a similar problem and a gm garage took my instrument panel out and sent it off, there was a coroded connection on a transistor. (200 bucks) get it fixed

EITHER U HAVE A OPEN ELECTRICAL CONNECTION THAT IS HEATING UP AND GROUNDING TO SOMETHING REDUCING THE VOLTAGE. CHECK PARTS THAT R CONNECTED DIRECTLY TO THE BATTERY AND THE PATH OF THEIR LINES.STARTER , ALTERNATOR.
