Low coolant light stays on - 2002 Chevrolet Impala

You may have to reset it by putting in a code. You can find the code in your owners manual. In our Grand Am we have to reset the Check Oil light after we change the oil. For the oil light it is something like press the gas peddle in 5 times within 30 seconds....something like that. Good luck

Many times vehicles have a coolant sensor mounted on the radiator that goes bad allowing the low coolant light to stay lit changing this sensor usually takes care of the light also make sure the wires running to the sensor are not shorted or broke.

reset the computer, if no change, replace the coolant sensor, but after reset it should work

if the coolant levei is ok
then replace the low coolant sensor on the side of the rad

if the coolant is full you need to check and most likly change the low level sensor in the coolant tank.

the low coolant sensor is bad needs replaced

Are you sure the coolant is still low in the bottle. The coolant sensor thats in the bottle has a float that can stick. If it sticks the low coolant light will stay on even if the coolant level is right. Try tapping on the coolant reservoir bottle in the area where the electrical wire enters it. Not too hard. If that is the porblem the light should reset.

Check you coolant resevoir. The low coolant switch is located in the resevoir so if it is low on coolant there, the light will come on. If it is full, it could be that the switch is stuck due to gunk build up in the resevoir. Hope this helps you out

check for something stuck in the wheels and as for the coolant light get the car running and up to warm temp and start adding coolant to the reserviour bottle until it is up to hot level because there maybe a bubble in the line but also if might be a bad switch in the reservior bottle itself

sounds like low oil pressure check oil pump, try thicker oil just to see
