    I ran into a spree of bad luck with my car 1998 Sunfire. But I just had the thermostat fixed and now the low water light is coming back on. What is going on with this car.

    I had to have the front swing bars both replaced. Someone stole my gas cap so had to buy a new one. replaced breaks. new tires (those were needed)

    I have owned my car for 6 years about. and never had a problem until this year.

    I wanted to sell before winter. and now that I have put so much money into this car I can not afford to even trade it in I will be looseing out.

You should look good around the radiator while the car is running for a while. then check the bottom of the overfill tank. If you can not find a leak ther then you can look at the hoses. dry everything up first let the car run to pressurize the radiator. I hope this helps

1998 sunfire temperature gauges quits working as soon as cooling fan comes on and check engine came on P0118 code

You may have a problem with the engine temp sensor or the wiring.
The fan would come on if the computer lost the signal from the sensor rather than the sensor failing because of the fan.
Low coolant is another possible cause.

Where is the valve located on a 1998 Pontiac Sunfire to insert/fill the freon?

Passenger-side near fire wall. Should have a cap on it that has an 'L' on it. You fill from the low pressure side. Gennerally the recharge bottle only fits on the low pressure side.

A thermostat that does not open and close would cause these very symptoms. Since it does not allow coolant to flow through the system, it will make the engine overheat. Since it won't allow the "heated" coolant to pass by your fan, the heat will continually blow cold air.
Stop driving the car immediately, becuase the next step will be some blown gaskets - especially head gasket. Other possible reasons can be as follows:-- It could be just low on coolant. if it is then add coolant... with low coolant the water pump can not move enough coolant to supply hot coolant to the heating system . also if its low the motor will over heat fast..... If the system is full then you may have other problems.. such as 1) bad thermostat 2) bad radiator cap ( not holding pressure so it will leak coolant) 3) blown head gasket . 4) bad heater core (leaking coolant out.. check the floor board under the dash on the passenger side.) 5) bad hose or clamp. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

My 1998 Pontiac Sunfire was flashing the coolant light, and today the check engine light is on

It is probably the same problem, you need to check the coolant level in the reservoir if it is full, then you need to check the coolant in the radiator. Make sure that you don't open it while it's hot, It will get you. You can also bring your car to advance auto or autozone, or most any other parts store and they will tell you why your check engine light is on, for free.

I have a 2001 Pontiac Sunfire and a symbol that looks like water waves with an arrow pointing down What does that mean. I have put antifreeze in

this can either mean low fuel or low coolant. if the fuel level is ok, and the coolant level is ok, chances are there is a problem with the coolant level sensor.

I don't know what the symbol means on my 1999 Pontiac Sunfire

does it look like a radiator? Low coolant sensor, may be in the overflow tank. Check your coolant levels when cold.
