It all starts with a series of in-depth diagnostic tests. We use a combination of computer-driven diagnostic technology and years of established knowledge of diesel engines to provide a comprehensive overview of your engine’s performance.


Diesel engines tend to be overbuilt so they can withstand the extreme compression pressure used to power them. This means that, on the one hand, diesel engines are built to last—and to take a lot of daily abuse. On the other hand, the extreme pressure requires absolute precision in both construction and maintenance. From air intakes and compression ignition to high-pressure cylinders and turbochargers, our diagnostic procedures are designed to test every component on your engine and to determine even the slightest problem.


If there’s an inefficiency or worse, damage, we’ll find it. We’ll fix it. We’ll get you back on the road, fast.
