5 tips for diesel engine maintenance

Caring for your diesel engine will prolong its life and save you money in the long run. There are certain elements that differentiate to petrol engines and can’t be swept under the rug, as you will pay for it in the future. Here, we look into just what you need to keep a lookout for… 

  1. Check your coolant levels

If your coolant isn’t maintained properly, it can damage additional parts of your diesel engine. For this reason, it falls under one of the top components to maintain. 

Essentially, the coolant gets more acidic as time goes on, so if it’s not flushed periodically, it can rot additional components in the cooling system, such as the radiator. 

How do you prevent this? It’s recommended to check your coolant once every couple of weeks, especially for vehicles that are used frequently and with heavy loads. You’d rather be safe than sorry.

  1. Change your oil when required

Checking your oil is a main maintenance job for any vehicle – if left unattended, your vehicle will face a range of issues and parts will wear down. 

Diesel engines require more oil changes than petrol engines. You should check your oil every six months or every 10,000km. 

While there are signals in vehicles which show when to change your oil, in our busy lives we may become oblivious to these. Setting a reminder on your phone may be the more realistic option. 

  1. Clean your engine

You’d be surprised at just how much a dirty engine can lessen the life of your engine. In fact, the easiest way for an engine to become damaged is by not cleaning it. Not only this, your engine performance will be affected. 

The oil, fuel and air are the three most important components to keep clean. 

  1. Monitor your engine’s filters

Your filters should be changed at specific times. For instance, when you change your oil, you should also change the filter. 

The air filter is one filter that accumulates a significant amount of dirt and should be changed every year to year and a half. Or, if you may not use your car the average amount, then be sure to change your air filter every 10,000km to 15,000km.

Not maintaining your filter will lead to a high chance of poor performance as well as an increase in fuel consumption.

  1. Drain your engine’s water separators

Unlike with petrol engines, you should drain your diesel engine’s water separator.

Condensation in your diesel engine can lead to the liquid contaminating your diesel. This is the case due to diesel engines not having vapour pressure in order to displace air. When the fuel tank in a diesel engine increases in temperature, the air expands and is pushed out. And when the temperature then decreases, humid air is pulled into the tank causing water to condense. 

Ultimately, the contaminated water can result in corrosion in the fuel system, so most vehicles with a diesel engine will have a water separator. It’s important to empty the water separator to prevent water build up, and in turn, corrosion.

Just like watering your plants, your engine requires some care. Have peace of mind by utilizing these 5 diesel engine maintenance tips to prolong the life of your engine.
