Some symptoms of a clogged radiator are overheating of the engine, a temperature gauge that register a high reading on hot days and when an air conditioner is on, and higher than usual coolant consumption. The causes of a clogged radiator are debris, corrosion and an internal buildup of deposit that lead to a decreased amount of coolant flowing through the radiator.
These causes of a clogged radiator lead to the mentioned symptoms. One way to detect a clog is to use an infrared thermometer. Another method to diagnose the problem is to do a radiator efficiency test that involves measuring both the inlet and outlet coolant temperatures. A blocked radiator may require either cleaning or replacing it.Learn More
A bad radiator cap can cause the coolant to boil over from the reservoir or the engine to overheat. The cap is an integral piece of an engine's cooling system as it retains the coolant´s pressure.Full Answer >
If engine oil ends up in the radiator, it usually is due to a cracked head or blown head gasket. If the crack is adjacent to the oil pump, the resultant pressure can blow either the radiator or a cooling hose.Full Answer >
Heat that is coming from inside the car as well as outside of the car can cause the temperature gauge of the car to increase. When temperatures are extremely high within the inside of the car, the temperature gauge will greatly increase and the car could suffer from many different problems.Full Answer >
A person can determine if the radiator needs flushed out by checking the color of the coolant inside. This is done by loosening the drain valve.Full Answer >
