It may have a bad temperature sensor.
My 01 Escape radiator light comes on intermittently and I can't nail down the precise conditions. 3 different Ford garages have told me the sensor in the coolant reservoir is bad. Bad news is that to replace the sensor you have to replace the whole reservoir; good news is that it only costs ~$75 at Autozone. Since I know that this is the problem I just keep an eye on the fluid level until I get a chance to replace it.
It could if you are running it in very cold or very hot weather. In the winter, the engine has to warm the fluids and since the fluids are cold and thick, it takes more engine force to move them. In the summer, they are too thin so the engine isn't fighting the viscosity of the fluids. It's always best to make sure antifreeze/coolant is full. Always check them when the engine is hot. NEVER check Radiator HOT!
There isn't a radiator drain plug. Instead, you have to loosen the lower radiator hose and drain the fluids. Be careful and don't do it after running the motor. Do it when the fluid is cold/cool. Also, wear eye protection, as the fluid tends to go everywhere!!
NO.
A radiator is defective if fluids are leaking out of the radiator or there is a leak of steam. Or, if thecore is blocked, the radiator will remain cold or just slightly warm in places.
The dipstick is located in the front of the engine block. It is important that you always keep your fluids checked to keep your vehicle working properly.
In a radiator, the fluids get really hot, when things get hot they expand and then they have to go somewhere, the fluid goes into an overflow.
the shop said it would cost around 400.00,labor about 2 hours and fluids and radiator
always use manufacture specified fluids for your vehicle, it will say in the owners manual and in the engine compartment somewhere close to the overflow resivoir
There are many reasons as to why a Sunfire may be running hot. Most likely the car is running low on coolant, or other fluids.
Maybe a blown head gasket. fix it quickly.
in the oil pan you have drain radiator and tranny fluids first
The transmission oil cooler inside the radiator is no good and allowing the fluids to mix. Not a good situation, don't drive it until it is fixed.
