1. Have a Clean Diesel Engine 

Naturally, your diesel vehicle gets dirty as you drive. Debris, oil, dirt, and road salt can quickly make your diesel engine home.

When there is dirt on the engine, it is harder to diagnose any problems. Some dirt, like road salt, can also lead to erosion and rust.

Maintaining a clean diesel engine means you will be able to identify any issues quickly. It also increases the diesel vehicle’s lifespan, saves on repair bills, and prevents engine failure.

2. Check Your Coolant and Radiator

The coolant in your car dissipates the heat created by fuel and air. If your coolant is too low, your diesel engine can overheat. It can lead to severe damage, such as to a head gasket, or your car could ultimately shut off. 

Signs your coolant level is too low include a high temperature on the dashboard or unusual odors. You may also notice your AC system is malfunctioning.

Check the coolant reservoir under the hood of your diesel vehicle at least twice a year. You need to top it up if it is below the minimum line. Also, check the radiator, as this is what sends the coolant through the system. 

3. Clean Air Filters

The air filter protects your diesel engine and car from contaminants. When the air filter is dirty or inefficient, more fuel than needed will enter. You may notice a reduction in power, fuel economy, noises, and strong smells.

You can purchase an air filter cleaner to safely and efficiently clean filters. 

4. Replace Diesel Engine Fuel Filters 

Fuel filters need to be changed every 10,000-15,000 miles to maintain your diesel engine. Most diesel engines have two or more filters. You can change these or get a professional to do it. 

Signs it is time to change fuel filters include misfiring and your car not being able to start. 

5. Do Oil Changes

Every 5,000 miles, you need to do an oil change. Some diesel vehicles need to have one more frequently, depending on what type of driving you do. Your diesel engine will quickly get damaged without the correct lubrication between parts. 

Make Diesel Engine Maintenance a Habit

Once you get into a habit of diesel engine maintenance, these steps will feel second nature. And it is worth it because you will notice any issues early on, which saves on repair bills. And your diesel vehicle will last longer!

Check your diesel engine weekly, keep an eye on your mileage, and carry out these tasks when needed.
