Why would the coolant light come on after replacing the coolant in the reservoir of a 1997 Pontiac Sunfire?

Fill the RADIATOR with coolant. If it is full the sensor needs to be removed and cleaned.

Air bubbles in the system will cause this. I'm told it is very difficult to remove air in the coolant in Sunfires, & sometimes raising the front of the car with a towtruck is the last resort. Ramps under the front tires might work. It took us 2 visits to the mechanic to get all the air out.

I have had this problem with my 1997 Sunfire. Its a 2 door Coupe. The engine overheated, and the coolant light came up. I almost had my head gasket repaired, and come to find out, the coolant cap was wore out, causing the coolant to leak, causing the light to come on, and the engine to overheat.

I had the same problem with my 2.4 1998. After serveral trips to the mechanic, replacing the thermostat twice, replacing the pressure hoses and countless gallons of coolant I found out the water pump was bad. Get this looked at ASAP!!! I waited a few months until I was able to afford the pump replacement (cost me $1100). This also included replacing the timing chain, which any mechanic will suggest and I would agree.

Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.

The plastic tank is held on with a single bolt.It's below the tank toward the front of the car. Use plyers to slip hose clamps off.

A 1996 Pontiac Sunfire uses Dexcool coolant. This should only be mixed with distilled water, never tap water. Replace the coolant every 2 years or as needed.
