Diesel Repair in Cincinnati, OH

There’s no doubt that diesel engines are coming back – they are no longer loud, noxious power plants that struggled to start in the winter. The diesel engines in today’s cars and trucks are environmentally friendly, fuel-efficient, powerful and dependable. Even so, they still need regular maintenance and diesel repairs. Diesel repairs require expert technicians with specialized knowledge, like our ASE-Certified Master Technicians and ASE-Certified Technicians here at ProTech Autocare. Since 1997, our BBB-accredited shop has been providing expert, affordable diesel engine repairs for everything from an older Dodge Cummins to a state-of-the-art Mercedes BlueTEC engine.



Why Choose ProTech Autocare for your Diesel Repair?

Experienced and Trustworthy Technicians Dedicated to Quality Diesel Repairs

Diesel engine components are different from those found in gasoline engines, so they need technicians who are educated and experienced in diesel repair and service. Our technicians know the ins and outs of a wide variety of diesels, from economic diesels found in cars to the powerful, high-torque diesels found in heavy-duty trucks. Our technicians can perform diesel repairs including:

  • Injector Repairs
  • Gasket Repairs
  • Cooling System Repair
  • Oil and Oil Filter Changes
  • Spool Valve Failure

Thorough diesel inspections

Every diesel repair begins with a thorough inspection. We use visual and mechanical inspection, along with computerized diagnostics, to find any issues that may be occurring with your diesel. We pride ourselves in staying on the cutting edge of today’s technology with specialty training, factory scan tools and computer programming capabilities to make accurate diagnoses. By using a variety of methods, we ensure that we find the malfunction quickly and accurately, to save you time and money.

Comprehensive and transparent overviews of your diesel diagnosis

We will seek out every issue, major or minor, so that we can provide you a full overview of the repairs your diesel engine may need for a long, healthy life. Once we have gone through everything, we can present you with the diagnoses. The technician who works on your vehicle will be there to answer any questions you may have – part of what we do at ProTech is educate our customers about their vehicle.

Diesel repair recommendations you can trust

Our full, transparent overview comes with recommendations from our technicians on how to proceed. We will let you know which diesel repairs are essential, and which ones may be helpful but not vital. This allows you to make an informed decision that works within your budget and time frame. We will never pressure you to move forward with any repairs, and we will never perform any diesel repairs without your full approval.

Your diesel repair performed with quality replacement parts

While they are durable and reliable, diesel engines are still sensitive to poor quality parts. At ProTech Autocare, we use only the highest-quality OEM and aftermarket parts, so that we can ensure proper fit and a long life ahead for your diesel engine.


A place where customer service is number 1 with them. Going the little extra to make sure your auto is 100% and keeping me informed on all work being done are the reasons I have taken all my cars over the years to ProTech Autocare
