Radiators for Sale Pro Auto USA has got you covered when you need to replace your vehicle’s radiator. Your vehicle’s radiator provides cooling to your engine’s hardworking parts, and a leaky or malfunctioning radiator can cause your engine to overheat, damaging your engine’s internal components and leaving you stranded and facing costly repairs to key engine parts. Most internal combustion engines are water-cooled by means of a radiator. The majority of cars and trucks manufactured after 1980 have radiators made from aluminum due to its light weight and ability to effectively transfer heat. Radiators serve as a heat exchanger and have many tubes that are filled with a combination of water and antifreeze. The vehicle’s water pump circulates this coolant mixture through the engine block allowing it to absorb the heat produced during the combustion process. The heated mixture is then returned to the radiator for cooling and the process repeats. The liquid travels through the radiator’s tubes, which are surrounded by fins to allow more contact with air. Radiators are usually situated at the front of the vehicle, behind the grille, to capture the airflow created by the vehicle’s motion. Most radiators also have a cooling fan that assists in creating enough airflow to cool the liquid mixture. Even though a radiator cools the liquid after it leaves the engine block, the fluid in the radiator is very hot. Even a small puncture in the radiator will produce steam, a sign that the radiator is malfunctioning. Radiators are also prone to corrosion from the coolant and can become clogged. Making sure your vehicle’s engine is staying cool is one of the best ways to ensure a long life for your car or truck. Running […]
Superchargers for Sale
Superchargers for Sale Pro Auto USA is your source for quality auto parts! If you are looking to add horsepower, have your hot rod look, perform and sound like the powerful machine that it is, and boost efficiency, a supercharger may be just what you need. Pro Auto USA has the top brands in superchargers to make your car perform at its best. Simply input your vehicle’s make and model into the easy parts finder box to locate the supercharger that will fit your car and your budget. The supercharger has been around for awhile. It was invented in the late 1800s and put to use on one of the earliest internal combustion engines. In 1921, Mercedes was the first automaker to put a supercharger on a series of vehicles distinguished as “Kompressor” models. The internal combustion engine is powered by fuel that is vaporized by air. This process takes place in either a carburetor or fuel injection system. After vaporizing, the fuel/air mixture goes into the intake manifold where it is pulled by the downward stroke of the piston into the cylinder. When the piston returns, the fuel/air mixture is greatly compressed and then ignited by the spark from the spark plug. This explosion causes the piston to advance again. When the engine is given more fuel/air, the pistons move faster and with more force. This results in increased horsepower. A supercharger is basically an air compressor with a cooling system that delivers cooler, more compressed air to your vehicles intake. This allows a higher fuel to air ratio, which delivers more useable fuel to your engine and greatly increases torque and power. There are three types of superchargers used in automobiles today. The […]
Engine Control Module
Engine Control Module Scania Group / Foter.com / CC BY-NC-ND Pro Auto USA knows that the computer control module for any vehicle is the electronic monitoring heart of the engine. The computer control module, also called the powertrain control module (PCM) has circuit boards housed in a metal case that sit in the engine compartment. It’s sole job is to monitor various engine performance systems, like the air/fuel mixture for proper emissions through the catalytic converter, or the timing spark that governs engine firing ignition. It also determines and adjusts the idle mixture for proper warmup. The closed loop feature of the module takes care of the system automatically. The closed loop feature allows the computer to work by preset programs when the engine is cold. Think of the engine control module as a traffic cop that interprets all engine performance signals from the various sensors, and then adjusts them to exacting performance parameters. Many sensors are involved that have specific duties, and they include the throttle position sensor, coolant sensor, oxygen sensor, mass air flow sensor, air intake sensor, knock sensor, crankshaft and camshaft angle sensors. The control module has information cells that store the code for optimum engine performance. The control module can read the data from one or all of these sensors at a very fast rate, interpret the data and then send back the proper code to adjust the sensor. The engine control module can also alert the driver if one of the sensors has failed, which could result in a rough running engine. A dash light that shows “Service Engine Soon”, or “Check Engine” is a common warning of sensor failure or a component failure that will not allow the […]
