What Happens When Air Enters Your Diesel System

Diesel engines are sought after because they have more torque. With more torque comes more power, which is often needed for tasks such as towing and navigating through tough terrain. Another benefit of diesel fuel over gasoline is higher efficiency.  The maintenance of an engine with more power requires certain conditions for optimal function, and those conditions are best achieved when contaminants are prevented from infiltrating its fuel system. Investing in proven air separation components such as AirDog parts can prevent the headache of air issues. If you ignore early symptoms such as a decreased speed or fuel efficiency, the fix may get more complicated.

How Air Gets In

If the oil filter is changed and precautions are not taken, you will very likely have an air problem on your hands. Sometimes the culprit is a bit less obvious, such as a minuscule hole that can develop in a fuel line. Another possibility is a faulty seal, which could be difficult to detect without a thorough check of every inch of the system. Whatever the reason for this sneaky invader, it should be addressed as soon as possible.

How Air Affects Your Engine

Because air causes bubbling of the fuel in the line, the line will be blocked and the fuel will be unable to fully reach the engine. When the engine doesn’t receive the fuel supply that it needs, it stops. Once this problem has developed, corrective action such as line bleeding may be required. You will need to perform a symptom check of your vehicle, which can sometimes be time-consuming and requires special tools. If you discover that you need to bleed the lines after running diagnostics, you may want to get a tow to a trusted mechanic so that the process is performed correctly and you do not experience more issues.
