Truck Engine Diagnostics & Overhaul Service in Tennessee & Mississippi

For professional truck Engine Diagnostics & Overhaul Services from expert diesel mechanics in Tennessee & Mississippi, call Specialized Truck Repair today.

Keeping your truck's engine healthy is one of the most essential aspects of fleet maintenance.  If your truck engine maintenance is neglected, you run the risk of unnecessary engine repairs.

BENEFITS OF HEAVY DUTY TRUCK DIAGNOSTIC

A few of the benefits of engine diagnostics are:

  • Retrieve active/inactive/historical fault codes
  • Keep track of data and information about your engine
  • Save you money, time and effort in the long run

Here at Specialized Truck Repair & Fleet Maintenance, we believe in the importance of a healthy engine. We recommend our clients have their trucks’ engines scanned on each service interval.

If you notice any of these problems, it is likely time to bring your vehicle in to get an overhaul immediately:

  • Your engine has spun a rod bearing. This is one of the worst failures that can occur inside your diesel engine.
  • Your engine has very low or no oil pressure. A fuel or coolant leak can contaminate the engine oil, which leads to a high oil level in the crankcase.
  • Your engine has dropped a valve. This is an all too common and critical fault of a diesel engine.

If you notice these symptoms, it is a good idea to talk to a mechanic about the possibility of getting an overhaul:

  • Your engine has high blow by. Blow by is the compressed fuel and air mixture in the combustion chamber leaking past the piston and entering the crankcase.
  • Your engine is consuming a lot of engine oil or coolant. If your diesel is suddenly using up more oil or coolant, it could be from a variety of problems.
  • You have put a lot of miles on your diesel and are getting lower fuel efficiency. Vehicles with a diesel engine should come with a recommendation as too when you should get an engine overhaul based on mileage. Consult your owner’s manual or ask an expert about what they would recommend given the year, make, and model of your vehicle.

These are just some of the issues that can arise and indicate that it is time to have your diesel engine overhauled. If you notice any of the above problems or think that you might need an overhaul, you should bring your vehicle to a trusted mechanic with ASE certified technicians.

What is an engine overhaul?

An engine overhaul is a major diesel engine repair that involves the removal, disassembly, inspection and repair of an engine. During the overhaul, small parts and components, like bolts, might be replaced with new factory parts. During disassembly, the engine is cleaned thoroughly to remove built-up grime and debris. Since your entire engine is being taken apart, it’s much easier for the mechanic to identify problems and replace malfunctioning parts. Once everything has been cleaned and the necessary replacements have been made, the engine will be put back together and set back into the vehicle.

Benefits of an engine overhaul

An engine overhaul is an excellent option for engines that aren’t old or excessively worn but are still experiencing issues. An engine overhaul can effectively fix any issues with your engine and save you a significant amount of money. Since all of your parts and components are thoroughly cleaned and inspected during an engine overhaul, your mechanic will be able to spot minor issues that you might not have even noticed yet.

How do diagnostics improve truck repair efficiency?

Diagnostics improve efficiency by providing precise fault detection, reducing downtime, and enabling cost-effective repairs. Advanced tools interpret trouble codes and system data, allowing technicians to address issues quickly and accurately. This minimizes trial-and-error repairs and enhances vehicle reliability.

Critical: Professionalism, QualityI wouldn’t use the clowns again! Came in because my regen light was on and wouldn’t go off and check engine fault code was on. They preformed 2 parked regens and used their computer. They said I needed an ECU update, but I just had the ECU replaced 3 months ago. Then they tell me their computer can’t update the ECU because their software is out of date. But yet they still charged me $193.49 for using the computer. It was a complete waste of my time and money. They didn’t get anything resolved, they must be desperate for money!Service: Auto engine diagnosticI wouldn’t use the clowns again!

Paul was great with me, was broken down with leaking air line, got me out in a timely manner. Employees seem highly no l knowledgeable. Prices were given before with started (after they assessed problem). Everyone was super nice and friendly. I used to own a auto repair shop so I understand some of these reviews, one time we had a customer for an oil change, in our shop the car didn't start, he called police we assessed problem and his fuel pump went. One customer accused us of stealing her speakers! From what i saw this place is five star.Paul was great with me, was broken down with leaking air line, got me out in a timely manner.

Positive: Professionalism, Punctuality, Quality, ValueI will recommend anyone and everyone to Angel’s Truck Service. My family and I were on a road trip and were in desperate need of help with our lights. We walked into the shop and everyone was extremely busy there. Even with them being busy, Tyler came out to help us right away! He was professional and knew how to get the job done. Within 30 minutes my family and I were back on the road. We called 5 other RV/truck repair shops that all said they were too busy to help us. We are so thankful and grateful that Angel’s Truck Service understood that we had an emergency and jumped to the rescue. Thank you for helping make our trip safer and a much better experience.Service: ElectricalI will recommend anyone and everyone to Angel’s Truck Service.

These people took such great care of me. This is my 1st box truck but they had no problem going over the truck with a fine tooth comb or explaining different aspects and functions of the truck. The pricing was affordable as well. They have definitely won my business!!!Thanks guys!!!

Our business requires that our trucks be up and running constantly. We run an extremely tight schedule with our equipment. We don't have time for our trucks to be down. We have scheduled the mobile trucks to be to us when our truck arrive to our location to take care of repairs. Specialized Truck Repair has never failed us. We can count on them 24 hours a day. Thank you for always going the extra effort to help us succeed!

Brought my truck in because the air vents were not working right. When I turned on my heat it would blow cold out the a/c vents. The tech Kevin had my dash tore apart and fix the problem and had it all back together in an hour. Thanks for the great job.
