A diesel engine truck being maintained in the shop’s garage. People who drive diesel trucks love them because of the better fuel economy and less frequent maintenance. However, you still can’t ignore the maintenance that is required. If you want your diesel truck to last hundreds of thousands of miles, you must stay on top of factory-recommended maintenance. Mevert Automotive & Tire Center in Steelville IL has auto technicians specializing in diesel truck maintenance and repair. Additionally, some maintenance chores not listed in the factory recommended maintenance list also help make your truck last longer.

1. Clean the Engine

Diesel engines usually last longer than gas engines, so you should clean them more often. During the cleaning process, you could locate an oil or other fluid leak before it gets out of hand. Additionally, dirt and dust get into the engine compartment and build up on the engine, shortening the life of the components. Salt and chemicals from winter roads also corrode the engine and its components faster if you don’t keep it clean.

2. Air Filters

Check the engine air filter. If the filter is dirty, a diesel truck won’t run well. And, if it’s clogged, a diesel truck may not run at all. In most cases, diesel truck filters should be replaced every 12,000 miles. However, if you drive on a lot of gravel roads or use your diesel truck in the fields, change the air filter every 6,000 to 8,000 miles.

3. Regular Oil Changes

Always make sure you change the oil based on the manufacturer’s recommendations. Most shops replace the oil filter when they change the oil. Dirty oil clogs the engine and can cause it to overheat or shut down.

4. Inspect the Glow Plugs

Every time you get an oil change, you should check the glow plugs to ensure the nuts at the top haven’t backed off. A diesel engine doesn’t use spark plugs – instead, it uses glow plugs to generate heat in the cylinders, as diesel is less volatile than gasoline. If you have a bad glow plug, your diesel truck will most likely not start.

5. Check the Water Separator

The water separator is a filter that stops water before it contaminates the fuel. Diesel fuel creates condensation, so you need to check the water separator frequently. Most have a screw on the bottom that you can loosen to allow the water to drain. The water separator is usually located near the fuel filter.

6. Flush the Radiator

Diesel engines usually run hotter than gas engines, which means the radiator is subject to higher temperatures. Flush the antifreeze and replace it with fresh, as recommended by the manufacturer. Antifreeze has properties to keep the engine from freezing in the winter as well as overheating in the summer since antifreeze has a higher boiling point than water. When those chemicals evaporate or are destroyed, the antifreeze will no longer protect your engine. If the engine overheats, it could cause broken head gaskets, warped heads, or complete engine failure for seizing up.

7. Replace the Fuel Filters

Most diesel engines have two fuel filters – one between the gas tank and the engine and the other between the transfer pump and fuel injectors. Be sure to change both every 10,000 to 15,000 miles, as diesel tends to absorb more condensation than gas.

8. Use Diesel Treatment

Add a bottle of diesel treatment every time you fill your tank. The treatment helps keep impurities in the fuel out of the engine. It also has ingredients to help keep diesel fuel from gelling in extremely cold temperatures.

9. Check the Belts and Hoses

Every time you get an oil change, you should check the belts and hoses. While the number of miles to replacement varies based on how you drive the truck, you can expect to get about 60,000 to 80,000 miles out of them.

10. Rotate the Tires

Every month, check the tires for proper air pressure. If the air pressure is too low, you could decrease fuel economy. You’ll also wear the tires out much faster. If the air pressure is too high, you’ll wear out the center of the tire tread and have less control over the vehicle. Additionally, balance and rotate the tires at every oil change. They could lose balance weights, and each tire wears differently than the others. Rotating the tires evens the wear on the tread.
