Steering Columns for Sale The steering systems that are produced for the global auto market feature technology that has improved vehicle operation. A steering column is often the most underrated vehicle component apart from the engine and transmission. Researching a replacement assembly through online retailers does take a level of understanding about the different steering columns for sale online. Pro Auto USA carries one of the largest inventories for replacement motor vehicle parts and accessories. Why Steering Columns are Hard to Find The removal of integral auto parts from a vehicle usually takes trained professionals. A person who specializes in the removal of a steering column has to have the right tools to complete the job. The average person does not have access to a column puller to remove an old column in hopes of completing a new installation. There are a limited number of qualified repair personnel in the U.S. who have steering column pullers. This is what can make a column rare to find through the second hand market. Most Common Steering Columns in Use 1. Standard The standard edition column dates back before the turn of the 20th century in vehicle production. These regular columns are still in use today as a basic option for some vehicle brands. These consist of a regular shaft that is a one-piece unit. These are commonly found in all automaker brands from 1920 to 1980. Some units feature a 3 to 4 speed shifting mechanism. Buying a standard edition steering column is quite common. Finding one that is in excellent condition can be more of a challenge. 2. Tilt A tilt column provides more flexibility for drivers. Unlike the stationary installation that a standard unit provides, […]
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 […]
Cylinder Heads for Sale
Cylinder Heads for Sale Looking for used or re-manufactured cylinder heads for sale? Check our extensive inventory of parts by searching for your part above. What Are Cylinder Heads Cylinder heads are a fundamental automotive engine component, and are responsible for proper engine performance. They are a large, metal cast components that sit directly over the block, serving as a compression seal for the cylinders. They are typically made of cast iron or aluminum, and are precisely machined within exact tolerances. Inline engines have one long head with anywhere from four up to twelve cylinders, while V-6, V-8 and larger engines have two heads that split the total number of cylinders between them. They house the compression chambers, intake and exhaust ports and valve seats. They have interior water channels that connect with the water ports in the block so that antifreeze can pass through both for the purpose of keeping the engine at a specified operating temperature. The head holds various valve train components, typically consisting of rocker arm shafts, intake and exhaust valve seats, tappets, springs, keepers and valves. Some heads contain the camshaft which is responsible for opening and closing the intake and exhaust valves during a regular 4-cycle stroke period. More Information The cylinder head is subjected to the highest temperatures in the entire engine. This is a result of the explosion or power cycle within the cylinder. The most harm to cylinder heads comes in the form of excessive heat which allows sever expansion, flex and even cracking of the cast material. Head gaskets are metal or carbon composite gaskets that keep a seal between the cylinder head and the block—they can blow out or deteriorate, leaking exhaust gases, oil […]
