Radiators for Sale

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 […]

Transmission Control Modules For Sale

Transmission Control Modules For Sale Pro Auto USA parts supply has vast experience when it comes to identifying and selling transmission control modules, or TCMs. The TCM, a small electronic computer encased in a box, is usually mounted on the firewall behind the engine. It is a small, compact CPU that interpret signals from various sensors which govern transmission operations. It works in conjunction with the engine control module, but primarily is responsible for selecting the proper gear and shifting time that allows the vehicle to maintain optimum performance. It measures different input information from sensors, like engine RPM, throttle position and vehicle speed. Once it receives signals from the various sensors, such as the turbine speed sensor, vehicle speed sensor, kick down switch, cruise control, brake light switch, transmission control and transmission fluid temperature sensor it activates a solenoid inside the transmission. The solenoid valve directs transmission fluid to disengage or activate small brakes and clutches in the transmission that control the gear shifting sequences. This prevents slippage and lag time when the vehicle needs to shift properly during different driving conditions. What does the TCM do? The TCM promotes smoother shifting, better fuel economy, reduced emissions, improved shift timing, shift feel, faster shifting speed and better overall handling and response. It performs this function if the transmission is up-shifts or down-shifts, or in any of three modes: manual, automatic or semi-automatic. When the TCM receives a fault signal from one of the sensors or a related component, like the trans-axle, it stores and saves a fault code. It deletes the fault if it can not identify it. The newest transmissions that have the 5-speed automatic option have control modules that keep the transmission […]
