DIY Car Repairs Every Driver Should Know

The duty of car ownership includes thorough understanding of vehicle maintenance because vehicles demand responsible care. Regular maintenance practices both avoid expensive car repairs and offer longer vehicle lifetime. All vehicle owners need to understand basic car repairs which do not require professional expertise about performing primary maintenance themselves. The DIY fixes will both decrease your expenses and reduce your towing costs along with saving you from getting upset. The following text presents some key self-performable vehicle repairs alongside step-by-step instructions and proper mechanic contact situations.

1. Changing the Engine Oil

Changing engine oil stands as among the most vital automobile repairs which also remains straightforward to perform. Your engine functions best with engine oil because it maintains part lubrication and keeps engine surfaces cool while fighting against friction and wear. The lifespan of oil shortens until it reaches a level where replacement is necessary.

How to Change Engine Oil:

• Materials needed: Engine oil, oil filter, oil filter wrench, socket set, funnel, oil pan, gloves, and jack (if needed).
• Steps:
  1. Park your car on a flat surface and let the engine cool down.
  2. Lift the car if necessary using a jack and support it with jack stands.
  3. Place the oil pan underneath the oil drain plug.
  4. Unscrew the drain plug with a socket wrench and let the oil drain completely.
  5. While the oil is draining, remove the oil filter with the oil filter wrench.
  6. Apply a little oil to the rubber gasket of the new filter and install it by hand.
  7. Once the oil has drained, replace the drain plug and tighten it.
  8. Use a funnel to pour in the new oil according to your car’s specifications.
  9. Start the engine for a few seconds, check for leaks, and make sure the oil level is correct.
  10. Dispose of the old oil properly by taking it to a recycling center.

Changing your oil every 3,000 to 5,000 miles (depending on your vehicle’s requirements) can help keep your engine running smoothly.

Replacing your air filter every 12,000 to 15,000 miles can improve your car’s fuel efficiency and engine performance.

3. Changing the Spark Plugs

Spark plugs play a key role in igniting the fuel in your car’s engine. Over time, spark plugs can wear out or become dirty, causing poor engine performance. Replacing them is relatively simple and can improve your car’s fuel efficiency, acceleration, and overall performance.

How to Change Spark Plugs:

• Materials needed: New spark plugs, spark plug socket, ratchet wrench, spark plug gap tool, and anti-seize lubricant.
