Diesel engine Repair, Replacement, Maintenance & Service

Why You Need a Diesel Engine Repair

When it comes to diesel engines, you’re not dealing with anything wildly different than a gasoline engine. However, diesel engines are designed to compress air twice as much as gas engines, meaning that the engine parts are “more robust” in order to withstand this amount of pressure. If you drive a vehicle with a diesel engine, you’ll need to regularly service and maintain it to stay safe. Without frequent repairs, your engine can behave oddly and consequently ruin crucial parts, or even fail on you! Make sure you take care of your engine so you can avoid these dangerous hiccups.

Common Symptoms of a Malfunctioning Diesel Engine

If your car has trouble starting, makes funny noises, or releases black, blue or white smoke, you might need a diesel engine repair service. You should also keep an eye on the amount of power being delivered to your engine, how much oil it’s consuming, and overheating. Of course, if your car doesn’t start, you should have a mechanic take a look at it to figure out what’s wrong. 

These vehicle behaviors can all be symptoms of a malfunctioning diesel engine and can be due to:

You can learn more about how to troubleshoot your vehicle here, or better yet, leave it to the professionals at TLC Auto & Truck Repair Service Center.

How does the shop repair your diesel engine?

When you take your vehicle to a mechanic for a diesel engine repair service, they will spend some time diagnosing the issue before tracking down the issue(s). They’ll then give you an estimate, including what needs to be done for you to get back on the road safely, how many hours it should take, and what that should cost you. After diagnostics, your mechanic will remove the defective parts and install new ones. They will then test those parts to make sure they’re working properly, and you can get back on the road!


Unfortunately, diesel engine repair services can be relatively expensive, as there are a number of things that can go awry within a complex engine. Some repairs like standard parts replacements can take as little as an hour to a few hours, but sometimes an engine requires an overhaul which can reach into the 20+ hour range. If you have a good mechanic, you’ll rarely overpay for a diesel engine repair, because they should be able to find and fix the issues within a day or two.

Spend less

When you keep your car in good shape, you’ll be able to save on maintenance. You’re also less likely to wear out other related parts if your vehicle’s systems are running correctly. Regular servicing is preventative care for your car!

Peace of mind

Getting your diesel engine serviced by professionals can save you the trips to and from the parts store, as well as avoid the many possible errors in part purchases, installation, and proper functioning of the whole system. Leave it to the professionals!

Diesel Engine Repair

While you can sometimes safely replace parts on a diesel engine on your own with some basic tools, it’s best to leave it to the professionals. Paying for services to be done right can be a life-saver in the most literal of ways. If you replace parts incorrectly or miss another defective part while you’re investigating, this can lead to more issues in the future.


It’s also important to make sure the components of your vehicle’s systems are in good working order. This includes your fuel system, ignition system, electrical wiring harness, engine lubrication and cooling, exhaust system, transmission, auto body, and brake system. These systems all work together to ignite your engine and keep it running smoothly.

If a mechanic finds any other system issues while they’re replacing a part, they will give you a call and update you on the state of your engine. Depending on which parts your mechanic needs to repair or replace, a diesel engine service could take anywhere from an hour for a fuel line replacement to a few days.


Making sure you keep the parts in your fuel system up to date and in working condition is crucial to the proper functioning of your vehicle. Diesel engine repairs can be expensive, but we only do them if it’s absolutely necessary. Regardless of the issue(s), TLC Auto will communicate with you before servicing your vehicle. You can rest assured that your vehicle is in good hands and that you get to make all the calls!
