you need to get the engine checked
Could be a faulty thermostat switch in the radiator !!
check the coolant level in the radiator
The thermostat would be the first thing I would check.
Fixer pluged radiator or caused thermostat to stick shut.
The parts that are needed to fix a car radiator depends on what is wrong with the radiator. It would be best to have the radiator fixed by a professional.
If a car shakes at stop light like it is going to shut off, this is probably caused by the AC compressor. To check on this, turn of the climate control and see if it goes away.
No, the alternator is used to charge the battery apperently.
The radiator cools the water which then goes to your engine to cool it off, as cool water enters your engine hot water from the engine enters your radiator
U NEED A THERMOSTAT. THAT IS WHAT HOLDS THE COOLANT IN THE RADIATOR, SO IT CAN COOL DOWN BEFORE IT GOES BACK IN THE MOTOR.
When your car is at idle there is no air flow to cool the radiator, but when your car moves the air flow through the radiator cools it down. I would suspect the radiator fan is not coming on when it should. If the fan is working properly the engine temperature should stay fairly constant assuming the thermostat is also 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.
Your radiator is your cooling system in your car so your car would over heat if you don't get that fixed soon and if it's a radiator at a house you would have no heat because that's a heater for your house
