One common sign a radiator is going bad is if it is leaking coolant, which can be caused by a crack. If there is green liquid found under a vehicle, then the radiator should be inspected to identify the area where the leak is present. A mechanic can perform a pressure test to determine the source of the leak.

Internal voltage regulators also can fail from too much heat. The best way to identify alternator problems is by conducting a bench test. A bench test will check the diodes and internal regulator and then tell you if the alternator is capable of producing its rated current and voltage.

Start the engine and let it idle for about 20 minutes to bring the engine to operating temperature—when the engine has reached operating temperature, you'll feel the upper radiator hose getting hot. When you see a stream of coolant free of air bubbles flowing through the clear hose, tighten the screw again.
