Some luxury diesel SUVs have emergency braking systems that can automatically stop the vehicle in an emergency.

Specifications and Maintenance of Diesel SUVs

• Regular oil changes

  Diesel vehicles use engine oil with higher viscosity. When changing the oil, the old oil should be completely drained out. The oil filter should also be replaced to ensure fresh oil circulates in the engine.

• Engine air filter replacement

  A new engine air filter allows maximum airflow into the engine for optimal performance. It should be replaced every 15,000 miles or as specified in the vehicle's manual.

• Fuel filter changes

  New fuel filters block impurities from diesel before reaching the engine. They should be changed every 10,000 miles or as the car manual recommends to ensure the engine runs smoothly.

• Regular coolant flushes

  The old coolant is completely drained out and replaced with fresh coolant. This prevents the engine from overheating and maintains its optimal temperature. It should be done every 30,000 miles.

• New transmission fluid

  Over time, transmission fluid breaks down. A mechanic will check the fluid's condition and change it if needed. This keeps the diesel SUV's gears shifting smoothly for many miles to come.

• Inspections of brakes and tires

  A qualified technician checks that the tires have even tread wear and sufficient depth for good traction on the road. They also inspect the brakes' pads, discs, and calipers for any issues so they stop the vehicle effectively.

• New spark plugs

  Diesel SUVs use glow plugs to heat the combustion chamber. These should be replaced around the 100,000-mile mark or as advised by the manufacturer. Fresh plugs ensure reliable engine starts in all conditions.

• Exhaust and emissions control

  The exhaust system should be free of leaks. The emissions control components are also checked to meet environmental standards set by law.

How to Choose a Diesel SUV

When buying a diesel SUV, consider the following:

• Driving Needs

  One's driving requirements should be considered. Those who often drive on highways may prefer a diesel engine for its fuel efficiency, while city drivers may choose a petrol engine for its quickness.

• Fuel Efficiency

  Check the mileage ratings of the vehicle. Diesel SUVs typically offer better fuel efficiency than petrol ones. Over time, this can save a lot on fuel costs.

• Torque

  Consider the torque of the engine. Diesel engines usually provide more pulling power, making them ideal for towing or driving with heavy loads.

• Longevity

  Research the lifespan of diesel SUVs. Generally, they can endure longer than petrol ones, but proper care and maintenance are essential.

• Environmental Regulations

  Be aware of local rules about diesel emissions. Some places have strict standards, and buyers may need to invest in additional emission control systems.

• Noise and Vibration

  Think about how much noise and vibration the car generates. Diesel engines are often louder and shakier than petrol ones. However, modern diesel SUVs are designed to be quieter and smoother.

• Cost

  Generally, diesel SUVs are more expensive than petrol ones. However, the long-term savings on fuel and maintenance might make it a wise decision.

• Resale Value

  Consider the car's resale value. Diesel vehicles may have a higher resale value in some markets, while petrol cars may be more sought after in others.

How to DIY and Replace Diesel SUVs

It's important to note that some diesel SUV car parts, especially the engine, are complex and difficult to handle. Therefore, it may be hard to DIY and replace. However, with the right tools and knowledge, maintaining and repairing minor issues in a diesel SUV can be done.

Before anything, it is important to read the manufacturer's manual for guidance. The manual provides valuable information on how to handle specific parts of the diesel SUV. Below are some basic maintenance activities that can be done with the right knowledge and tools:

• Changing the Fuel Filter

  Be sure to have a new fuel filter, a wrench set, and some rags. First, relieve fuel pressure by opening the fuel cap and using the fuel pressure release tool. Then, locate the fuel filter, which is usually found in the engine bay or along the fuel line. Use a wrench to remove the old filter carefully and avoid fuel spills. After that, clean the filter area and install the new filter in the same direction as the old one. Finally, use a wrench to secure the filter and ensure there are no leaks before starting the car.

• Changing Engine Oil and Oil Filter

  Get a new oil filter, engine oil, an oil wrench, an oil pan, and a jack and axle stands. Raise the car with the jack and place it on axle stands. Next, place an oil pan under the oil pan and use an oil wrench to drain the old oil through the oil pan. Then, remove the old oil filter and replace it with a new one. Finally, fill the engine with new oil through the oil filler cap and check the oil level using the dipstick.
