What happens when a radiator goes bad?

As the radiator goes bad, it will turn a rusty or oil color from contaminants. If not flushed periodically, this dirty coolant turns into sludge. By the time it turns to sludge, it will not flow properly to cool the engine efficiently and you may end up with extensive damage to the engine and transmission.

Can you drive a car with a bad radiator?

A cracked radiator can be dangerous to drive with because the engine may overheat. A cracked radiator does not allow the proper amount of coolant to reach the engine, which causes the overheating.

When the overflowing coolant reservoir does not return to the radiator the hot coolant that needs to be cooled down, means that there might be a leakage or clog of the radiator hoses that allow the flow of fluid from the coolant reservoir to the radiator. It can be a result of a damaged radiator cap.

What should I do if my radiator fan is not working?

The radiator fans have electrical motors inside of them, which will wear out after some years. You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector.

Do you need a radiator on an air cooled car?

Theoretically, radiators are completely optional on the engine. Air cooled engines have existed for a very long time. These radiators have cooling fins to extract the heat and release it into the air. However if your car was designed to require a radiator, you really need one.
