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 […]
Rotating electrical parts such as starters and alternators often have to be replaced on older, high-mileage vehicles. Fuel injection has helped prolong the service life of starters by allowing engines to start more quickly when they are cranked. Such is not the case with alternators. Higher electrical demands on charging systems have increased alternator failures. […]
Here to talk about exhaust gas temperature sensors or more commonly referred to as an EGT sensor. Now we have a 2012 Ram 2500 with the Cummins diesel engine it has the check engine light on and we’ve properly diagnosed that as being a faulty EGT sensor, and we’re going to show you how to […]
The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tail pipe. The honeycombed inner structure is covered with a layer of a chemical catalyst that […]
A diesel engine is a very complex machine comprised of many different systems working in tandem to combust fuel and get you where you need to go. As with any system, it is only as strong as its weakest link and one malfunctioning component could spell disaster for your entire engine. Even with with proper maintenance, sometimes […]
The weather is cooling down, and the leaves are starting to glow red and orange. Winter is around the corner bringing cold temperatures, steaming mugs of hot cocoa, snowmen, scarves, mittens, and hats. As fun as winter traditions can be, the weather can make the roads more hazardous with snow and ice. If you have […]
