Diesel engines are the workhorses of the automotive world. To keep these engines running efficiently, you need to perform regular maintenance. Here are seven tips for maintaining your diesel engine.
1. Change Your Fuel Filter
Your AirDog fuel filter should be changed about once every 10-15 thousand miles. If you have a newer engine, there may be a primary and a secondary filter. These will need to be changed periodically.
2. Check and Flush Your Coolant
Coolant can become acidic as it ages, causing parts, such as the radiator to rot. You should have the acidity levels of the coolant checked regularly and have the system flushed and the coolant replaced when the acidity levels become too high.
3. Inspect and Replace Air Filters
Air filters can be inspected without removing them from the engine. When they become clogged or overly dirty, they should be removed and replaced. If you are regularly driving in a harsh environment, your filter may need to be replaced more often.
4. Clean Your Engine Regularly
Excessive build-up of dirt and debris can severely damage your engine and shorten its road-life. It is particularly important to keep the engine oil, fuel and air clean. Storing and handling your fuel properly can help prevent the fuel from becoming contaminated with dirt and debris that can damage your engine. An engine that runs irregularly, misses or puffs black smoke may need to be cleaned.
5. Change the Oil
You should change the oil about once every 5 thousand miles. However, if you are working your engine hard, you may need to change it more frequently.
6. Avoid Water in the Fuel System
Even a small amount of water in the fuel system can cause your engine to miss and larger amounts can stop the engine completely. Water can enter the system with the fuel or from condensation. Any water in the system should be drained daily.
7. Keep Air Out of the Fuel System
Trapped air can cause the engine to be difficult to start. Air may get in the system through loose joints in the piping or spray nozzles that do not close properly. Air can also get in the system if you completely run the tank dry. Remove the air by bleeding the system.
Regular maintenance is essential for extending the life of your diesel engine and keeping it functioning efficiently. Consider adding these maintenance tips to your regular maintenance schedule.
