Top 10 Automotive Tool Hacks

In the industry of automotive repair and maintenance, proficiency with tools is as critical as having the right parts for the job. With advancements in vehicle technology, the tools required for auto repairs have also evolved, becoming more specialized and, in many cases, more expensive. However, not every situation warrants a trip to the auto parts store for a one-off tool purchase. Sometimes, creativity and resourcefulness can save the day, especially when you're in a pinch. 

This detailed guide explores some of the most ingenious tool hacks that can make automotive work easier, more efficient, and often less costly. These hacks demonstrate how common tools or items you already possess can be repurposed to solve automotive problems, proving that sometimes, thinking outside the toolbox is the best strategy.

Improvised Brake Bleeder

Bleeding brakes is a necessary maintenance task that requires precision to avoid air getting trapped in the brake lines, which can lead to spongy brake pedals and reduced braking efficiency.

Using a Plastic Bottle and Tubing

  • Simple Setup: Secure a piece of clear tubing to the bleed nipple on the brake caliper and run the other end into a plastic bottle partially filled with brake fluid.
  • One-Person Operation: This setup allows for a one-person operation, as you can easily see air bubbles leaving the system through the clear tubing.

Ensuring No Air Returns

  • Tight Seal: Ensure the tubing fits tightly on the bleed nipple and that the bottle is kept below the level of the nipple to prevent air from being sucked back into the system.

Safely Disposing of Used Fluid

  • Environmental Responsibility: After bleeding, responsibly dispose of the used brake fluid, as it is hazardous to the environment.

DIY Oil Change Tools

Changing oil is a fundamental task in automotive maintenance that doesn’t always require specialized tools.

Homemade Oil Funnel

  • Repurposing Household Items: Cut the bottom off a clean plastic jug or bottle to create a wide-mouth funnel, perfect for pouring oil without spills.
  • Steady Pouring: The handle of the jug provides a convenient grip for steady pouring and can be cut to fit securely in the oil fill hole.

Using Magnets for Drain Plug Security

  • Securing the Plug: Place a strong magnet around the oil drain plug to catch any metal filings or debris, preventing them from circulating in the engine.

Leveraging Wrenches for Extra Torque

  • Breaking Free Tight Plugs: If the oil drain plug is overtightened, loop the box end of one wrench over the open end of another to create a longer lever, offering more torque with less effort.

Emergency Serpentine Belt Replacement Hack

The serpentine belt is crucial for driving various components of the engine. If it breaks while you’re on the road, knowing this hack can be a lifesaver.

Pantyhose or Tights

  • Temporary Fix: In an emergency, pantyhose or tights can serve as a makeshift serpentine belt, driving essential components for a limited time.
  • Installation Guide: Loop the pantyhose around the pulleys in the same configuration as the serpentine belt and tie it securely. This should only be used to get to a safe location or repair shop.


  • Short-Term Solution: Understand that this is a very short-term solution and that pantyhose will not provide the durability or strength of a serpentine belt.


  • Safety First: Only attempt this hack in safe conditions and if you're familiar with the belt routing. Misrouting can cause further damage.

Stripped Screw Extraction

Stripped screws can halt your progress but can be dealt with using common tools.

Rubber Band Trick

  • Increased Grip: Place a rubber band over the stripped screw head and press the screwdriver tip into it. The rubber band fills the gaps and provides the necessary grip to turn the screw.

Glue Method

  • Adhesive Assistance: Apply a strong adhesive (e.g., super glue) to the screw head and press the screwdriver into it. Once set, turn gently.

Heat Application

  • Expansion and Contraction: Gently heat the screw with a soldering iron to expand it, then allow it to cool. This can break the corrosion bond, making it easier to remove.

Cooling System Leak Detector

Detecting leaks in the cooling system can be challenging, but there’s a simple way to make them visible.

DIY Pressure Tester

  • Using Air Pressure: Seal the system and apply air pressure using a modified bike pump with a gauge. Listen for escaping air or use soapy water to spot bubbles at the leak point.

Making a Radiator Cap Adapter

  • Custom Fit: Modify an old radiator cap by attaching a valve from an old bicycle tire to pressurize the system safely.

Safety Precautions

  • Monitor Pressure Closely: Avoid overpressurizing the system to prevent damage. Monitor the pressure gauge closely during this process.

Quick Spark Plug Gap Adjustment

Setting the correct spark plug gap is crucial for engine performance.

Coin Hack

  • Measuring Tool: In absence of a feeler gauge, various coins can be used for rough measurement of the spark plug gap based on their thickness.

Using a Hammer

  • Adjustment Tool: Gently tap the spark plug on a hard surface to reduce the gap, or use the hammer handle’s circular opening to slightly increase it.

Consistency is Key

  • Ensure Uniformity: Try to maintain consistent gap adjustments across all spark plugs for uniform performance.

Using Heat Shrink Tubing for Wire Repairs

Automotive wiring can often need insulation or repairing connections.

Insulation and Protection

  • Secure Connections: Apply heat shrink tubing over soldered wire connections to insulate and protect them from moisture and short circuits.

Creating a Watertight Seal

  • Enhanced Durability: Use a heat gun to shrink the tubing tightly around the wires, creating a durable, watertight seal.


  • Color Coding: Utilize different colors of heat shrink tubing to organize and identify wires easily.

Tire Tread Depth Measurement

Maintaining adequate tire tread depth is essential for safe driving.

Using Coins

  • Quick Check: Insert a coin into the tread grooves at various points around the tire. The amount of the coin that is obscured can give a quick approximation of tread depth.

Consistency Across the Tire

  • Wear Patterns: Check multiple points to identify uneven wear, which could indicate alignment issues.

Safety Margin

  • Legal Limits: Be aware of the legal minimum tread depth in your area and ensure your tires are always above this limit.
