Why does my radiator keep cracking?
A faulty Thermostat or a Leaking Head Gasket can cause Overheating or High Coolant Pressure inside the Radiator which can lead to a crack. Summer heat makes it more difficult for the Radiator to be cooled by outside air. If you do not change your coolant enough, the radiator can start to corrode and crack over time.
Where is the coolant in the radiator when there is no leak?
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
What to do if your Radiator Cap is bad?
The radiator cap may have build-up of debris causing the malfunction. You can try cleaning it with water and a toothpick, though it’s usually better to just replace it since it’s relatively cheap and engine failure is an expensive potential alternative. You can also get a radiator pressure tester to check for pressure leaks in the system.
What happens when the radiator is closed on a car?
When it’s closed, the coolant is blocked until the engine warms up. Engine manufacturers will install a thermostat that opens at the car’s operating temperature (usually either 180 or 212°F, or 82 or 100°C). While the thermostat controls coolant flow, the radiator’s job is to cool the fluid.

What happens when the radiator in a car goes bad?
The three parts that commonly cease working after the radiator goes bad are the thermostat, water pump, and heater core. Here is a breakdown of what each of these parts does and what happens when they fail. Each engine size and configuration has a specific ideal operating temperature.
There’s a COLD/MIN label on the tank indicating the ideal antifreeze level when the engine is cold. The coolant in the radiator should be just below the filler neck. When you are losing coolant but no leak is visible, several parts could be the guilty party.
What do you need to know about radiator repair?
Radiator repair and maintenance is essential to the health of your engine and your vehicle. The most common radiator repairs involve simple part replacement and radiator fluid exchange. Additionally, most vehicle manufacturers recommend replacing coolant antifreeze at regular intervals.
What should I do if my radiator fan is not working?
If they are, that confirms the fan relay and radiator fans are, indeed, working properly. If they don’t run, check the fuse. If that’s good, your problem may be a faulty engine coolant temperature sensor. Radiator fans come in two varieties—mechanical and electric.
