Automotive Diagnostic Specialties Diesel Repair AZ | Chandler Arizona Diesel Auto Repair ShopAutomotive Diagnostic Specialties' Diesel Repair Services

Automotive Diagnostic Specialties is a full-service diesel repair and diesel maintenance shop located in Chandler. We service and repair large and small diesel engines and vehicles, as well as all makes of diesel engines, including Cummins, Duramax, and Powerstroke.

While they offer a complete range of services, here are a few of the repairs that ADS customers often need:

  • Diesel Injector Replacement and Injection Repair: One of the key differences between a diesel engine and an unleaded one is the injection system. While unleaded systems inject fuel outside of the cylinder, diesel injectors actually inject fuel directly into the cylinder. This poses a different set of challenges when it comes to diesel injector replacements and injection system repairs as they must be able to withstand the heat and pressure inside of the cylinder while still dispersing the diesel fuel in a fine, even mist.
  • Common Rail Injection Repairs: Common Rail Injection systems have helped to transform the diesel engine from the slow, smokey, powerful train-like diesel engine of the past into sporty, fuel-efficient, and clean running engines. Its unique division of injections allows the Common Rail Injection system to precisely deliver the correct amount of fuel from its separated pressurizing system. At ADS they have the diagnostic tools and the expertise to provide customers with Common Rail Injection system repair and diagnostics.
  • Diesel Injection Pump Repair: Traditionally the diesel injection pump is run from the crankshaft by gears or a belt and delivers fuel based on the RPMs of the engine. Newer systems, including the Common Rail Injection system, utilize external pumps which are regulated by Electronic Diesel Control modules. Regardless of the specific set up of your injection system, ADS can help you with diesel injection pump repairs.
  • Diesel Engine Replacement: From time to time the unfortunate reality is that your diesel engine can be beyond repair. When that is the case, ADS can help with finding the correct diesel engine replacement for your vehicle, removing your old engine, and getting you back on the road.
  • Diesel Electrical Repair and Diagnostics: Diesel engines, like all engines, involve complex electrical systems. ADS service bays are equipped with electrical diagnostic tools to track down any hard-to-find electrical problems with your diesel vehicle and get your engine running smooth and your amenities working.
  • Diesel Transmission and Clutch: ADS offers diesel transmission replacements and services. It’s recommended that you have your transmission serviced regularly to prevent more costly repairs such as transmission rebuilds and clutch replacements in the future. At ADS they offer transmission repairs, replacements, and servicing.
  • Diesel Drivability and Performance: If you have concerns about the driveability or performance of your vehicle, ADS offers complete diesel driveability diagnostics and diesel performance upgrades.
