Your radiator is one of the engine’s unsung heroes. It’s responsible for essential heat exchange functions in your car’s cooling system. Working in tandem with the thermostat and water pump, the thermostat plays an important role in distributing coolant and also maintaining coolant temperature. And when the radiator doesn’t work, things heat up in a […]
Choosing the right fuel injector depends on the kind of fuel injector used in your vehicle. The common kinds of fuel injectors are: Single-Point or Throttle Body Injection (TBI) Systems: The throttle body injection systems were the first to replace the carburetors. The throttle body system included one or two fuel injectors in place of […]
The Crank Position Sensor, also known as the Engine Speed Sensor, measures the position or the rotational speed of the crankshaft. It then sends this data to the computer to tell it which cylinder should be fired at the crankshaft’s current position. The crank position sensor is important because it ensures that the engine cylinders […]
The most common problem with cylinder heads is cracks that occur often due to engine overheating. A cracked cylinder head may leak the coolant, due to which the engine will fail to cool efficiently. This results in further overheating of the engine. When a cylinder head cracks, it will also cause the oil to leak […]
Flathead Cylinder Heads: These were the first type of cylinder heads. Flathead cylinder heads simply protect the cylinder block and have no moving parts. These cylinder heads do not allow for an efficient air flow, and thereby provide a poor engine performance. Overhead Valve Cylinder Heads: These cylinders heads are superior to flathead cylinder heads. Overhead […]
A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber. This page covers the main function and various designs of cylinder heads, and their causes and symptoms of failure. The […]
Loss of current or low voltage Electric pumps can’t run without electricity obviously, so if anything prevents voltage from reaching the pump, the pump will stop working. Check the wiring to see if it is loose, broken or corroded. Dirt Debris in the tank can build up and clog the strainer, accelerate wear and tear, […]
An ABS (Anti-lock Braking System) is an enhanced braking system which is commonly found in newer automobiles. An anti-lock brake sensor or ABS sensor is a type of tachometer that measures the rotational speed of a wheel and passes it to the car’s Engine Control Module (ECM). The ABS sensor is also called the wheel […]
The oxygen sensor or O2 sensor is a probe that rests in the exhaust of a vehicle. This sensor measures the amount of oxygen that is mixed into the exhaust gases that result from the combustion process. This reading is sent to the Engine Control Unit (ECU), so that it can adjust the amount of […]
Thanks to compact engine compartments, air conditioning, turbocharging, and computer-controlled cooling fans, under-hood operating temperatures have risen dramatically. To withstand these extreme temperatures, most modern coolant hoses are now made from ethylene propylene EPDM rubber, which can endure operating temperatures ranging from -40 to +275 degrees F. Thanks to extremely crowded engine compartments, about 90 […]
