How to Find a Good Diesel Engine Repair Service Near Me?
The total cost of owning a diesel-powered vehicle over a period of five years is reported to be $20,000 less than the cost of owning a gasoline-powered vehicle during this same period. This cost saving is only accruable to owners of well-maintained diesel vehicles. Do not make the mistake of assuming that any type of mechanic can work on your diesel-powered vehicle - diesel engine mechanics are specialists and you can easily find one nearby.
When contemplating the decision of how to select the best diesel engine repair service near you, you should pose the following questions to the auto-mechanics to ensure that you end up with the most qualified one available:
Are You Licensed, Registered, or Certified?
Occupation-specific licensing is not usually required for diesel engine repair. This makes it even more important to make sure that any diesel engine repair technician or mechanic that you intend to hire has been duly certified by a reputable automotive repair and maintenance-related organization. Certification serves as proof that a technician or mechanic has attained a certain level of competence and experience in the area of diesel engine maintenance and repair and it gives you a feeling of confidence concerning the individual's ability to do a good job. While several organizations may offer certification programs to diesel engine repair technicians and mechanics, the most commonly recognized certifications in the automotive repair industry are the ASE certifications that are issued by the National Institute for Automotive Service Excellence. This organization offers certification tests in more than 50 categories of automotive repair and maintenance, including diesel engine diagnosis, repair, and servicing.
Note that the State of Michigan requires mandatory state-issued certification for all individuals that maintain and repair motor vehicles in exchange for a fee, and this includes diesel engine repair technicians and mechanics. Similarly, some states or local governments may require general registration or licensing for facilities that offer vehicle repair services within their jurisdictions. Therefore, it is advisable to contact the consumer protection office that is responsible for your locality to find out whether any requirements have to be met by diesel engine repair facilities, technicians, and mechanics that operate in your area. In addition, you should always validate any proof of certification, registration, or licensing that a diesel repair technician, mechanic, or facility presents to you by contacting the organization that issued these documents.
How Much Does It Cost to Hire a Diesel Engine Technician or Mechanic?
Diesel engine repair costs typically range from $150 - $500 for minor repairs to $3,000 - $8,500 for an engine rebuild or replacement. The cost of hiring a diesel engine technician or mechanic to repair or replace your faulty diesel engine is influenced by factors like the extent of damage to your engine and the make, model, and age of your vehicle. Some common diesel engine repair cost estimates are listed below:
- Air filter replacement - $25 - $100
- Engine oil change - $70 - $250
- Coolant flushes - $150 - $220
- Fuel filter replacement - $100 - $150 per filter
- Fuel injection system servicing - $250 - $450
- Diesel engine rebuild $3,000 $5,000
- Diesel engine replacement - $5,000 - $10,000
You can save money on costs when hiring a diesel engine repair technician or mechanic near you by taking note of the following tips:
- Carry out regular maintenance on your diesel engine and vehicle as a whole
- Get quotes from more than one diesel engine repair technician or mechanic when you have to do any engine repairs
- Find out the parts of your engine that may need replacement and buy them yourself
- Consider using salvaged or reconditioned parts for your repair or replacement
What Are Common Diesel Engine Repair Expenses?
Diesel engine repair expenses are usually limited to the actual cost of carrying out the required repairs. This includes the cost of buying any parts of the engine that may need replacement and the diesel engine repair technician or mechanic's labor costs. You should always get a detailed estimate of these costs before hiring any diesel engine repair technician or mechanic. Also, find out whether you will have to pay an upfront fee or if payment will be made after the repair job has been completed.
Finally, it is advisable to carry out regular maintenance on your engine, and your vehicle as a whole, after any repairs have been done. This maintenance usually includes oil and filter changes and it can cost you anywhere between $25 and $200. Doing this reduces the chances of your engine suffering a complete breakdown, thereby reducing the total cost of any future engine repairs or replacements.
Who Will Do the Work?
Whether you are dropping off your vehicle at a diesel engine repair facility or you are retaining the services of a particular diesel engine repair technician or mechanic, you should always have a clear idea of who will be in charge of the work that has to be done on your engine. This way, you can verify the credentials of this technician or mechanic and also ensure that any state or local government registration and licensing are duly met. Knowing who is in charge of your repair job also provides you with a specific individual to hold accountable if your diesel engine is not repaired properly or to your satisfaction. This is important, especially if you drop your vehicle off in a repair facility that employs several diesel engine repair technicians and mechanics.
Note that while some repair facilities that display ASE certification logos may claim that this certification covers all their technicians and mechanics, this is not usually the case. If a vehicle repair facility displays an ASE certification logo, this only means that at least one technician or mechanic in this facility is ASE certified. However, the National Institute for Automotive Service Excellence has a recognition program that issues a customized Blue Seal of Excellence logo to vehicle repair facilities where each area of service being offered is covered by at least one ASE-certified technician or mechanic. As such, if you drop your diesel-powered vehicle off at a repair shop that displays an ASE Blue Seal of Excellence logo, then it is very likely that your repair job will be handled or overseen by an ASE-certified diesel engine repair technician or mechanic. Nevertheless, it is always a good idea to get confirmation of this.
What Qualifications Should a Diesel Engine Repair Technician and Mechanic Have?
While diesel engine repair technicians and mechanics typically learn on the job after obtaining a high school diploma or its educational equivalent, many employers usually require these technicians and mechanics to also complete postsecondary education and training programs. These programs, which are usually offered by community colleges and vocational or trade schools, typically involve a mixture of classroom learning with hands-on training. Some diesel engine repair technicians and mechanics also obtain professional certifications from organizations like the National Institute for Automotive Service Excellence. In addition to demonstrating the diesel engine repair technician or mechanic's competence and experience to potential employers, these certifications also potentially increase their average income. Note that ASE-certified technicians and mechanics are typically required to pass recertification examinations every five years. Finally, diesel engine repair technicians and mechanics that work on large buses and trucks may be required to obtain a commercial driver's license before they can test-drive these vehicles.
The United States Bureau of Labor Statistics estimates that there are more than 253,000 bus and truck mechanics and diesel engine specialists currently employed in the country. Many of these individuals belong to trade associations like the Association of Diesel Specialists and the AERA Engine Builders Association. Note that membership in a trade association is not compulsory. However, diesel engine repair technicians and mechanics that belong to these types of organizations are required to abide by a specified code of ethics and this usually makes them more professionally behaved than the technicians and mechanics that are not members of any trade association.
Will You Provide References?
You can get referrals on a good diesel engine repair technician or mechanic near you through several methods, which include:
- By asking friends, family, and colleagues
By utilizing search portals provided by organizations like the National Institute for Automotive Service Excellence and the Association of Diesel Specialists
After getting referrals and reaching out to a technician or mechanic, you should always ask these individuals to provide you with at least three references. Getting references is a good way to make sure that you end up with a professional diesel engine repair technician or mechanic near you. Contact these references and get their honest opinions on the technician or mechanic. Be suspicious of any diesel engine repair technician or mechanic that cannot provide you with up to three verifiable references, and strongly consider hiring a different one. You can also search for reviews and opinions on the technician or mechanic through websites like Better Business Bureau, Yelp, or Google Review. Finally, it is also a good idea to contact your state's Attorney General's Office or consumer protection agency to find out if any complaints or reports have been filed against the technician or mechanic that you intend to hire.

Note that the quality of an engine rebuild is affected by the mechanic that does the job, and so you should always hire a professional diesel engine repair technician or mechanic to do this. In addition to this, you should always compare the cost of rebuilding your engine to the cost of replacing it. If the costs are almost the same, then it might be a better idea to have your diesel engine replaced instead of rebuilt.
