Car Maintenance And The Theory Test – Part Two

Part one of the series left you with the task of brushing up on your tyre maintenance knowledge in preparation for your theory test and practical exam. Part two, covers some other vehicle maintenance basics that could prove to be the difference in passing your theory test and practical test.

Fluid Levels

Questions regarding fluid levels are becoming a regular occurrence, and are arguably one of the most common questions asked prior to getting behind the wheel to take a practical exam.

Knowing the difference between where to refill a vehicle’s oil, or water for the radiator, could not only help you pass your practical exam, it could save you from potentially damaging a vehicle.

Common questions on the theory test regarding fluid levels include:

  • How often should you check the fluid levels of your vehicle?
  • What could low brake fluid result in?
  • What does ‘this’ fluid warning light mean?


With so many petrol variants on the market including unleaded, super-unleaded, premium unleaded and diesel, knowing what type of fuel a vehicle requires is important. The consequences of refuelling your vehicle with the incorrect fuel type could mean thousands of pounds worth of damage.

In terms of refuelling, you need to understand petrol station etiquette. Common questions about fuel stations on the driving theory test include:

  • What should you do if fuel is spilled on the forecourt?
  • Where on your vehicle would you look if you suspected a fuel leak?
  • Can you use a mobile phone at a petrol station forecourt?

The Engine

The engine is the heart of any vehicle, without it vehicles are simply unable to run. Therefore, it’s vitally important that you know how to take care of it if you want to keep your vehicle on the road. One of the biggest reasons for engine failure is overheating.

Referring back to fluid levels, making sure your engine has sufficient water or engine coolant for the radiator is crucial. However, should an engine overheat it’s important to know the steps required to cool the engine safely, without risking a potential fire.

Common theory test questions relating to engine maintenance include:

  • How might you identify a problem with your engine?
  • If your engine does overheat, what would be your first step to cool it?


The modern motorist is required to have a basic understanding of vehicle maintenance because, as vehicles evolve, the more a driver needs to know what it takes to maintain more sophisticated vehicles.
