How to Start a Car That's Been Sitting for Years

Introduction

This tutorial provides a comprehensive guide on how to start a car that has been sitting idle for an extended period, typically 4 to 6 months or longer. Whether you’ve purchased a vehicle from an auction or uncovered an old car in your garage, following these steps will help you safely start the engine without causing damage.

Step 1: Inspect the Vehicle

Before attempting to start the car, perform a thorough inspection.

• Check for Animal Nests: Look around the engine bay and grill for any signs of animal nests or debris that could catch fire or interfere with engine components.
• Remove Debris: Clear out any leaves, twigs, or other debris that may have accumulated.

Step 2: Address the Ignition Lock

If the key is difficult to insert or remove, follow these steps:

• Use Dry Lubricant: Apply a dry lock lubricant to the ignition lock. Shake the can and spray a small amount into the lock to ensure smooth operation.

Step 3: Check and Change Engine Oil

Proper oil levels are crucial for engine health.

• Inspect Oil Level: Use the dipstick to check the oil level. If it’s low or appears dirty, proceed with an oil change.
• Drain Old Oil:
  • Loosen the drain plug and allow the oil to fully drain into a container.
  • Catch an oil sample for analysis if needed.
• Replace Oil Filter:
  • Remove the old oil filter using tin foil to funnel any spills.
  • Install a new oil filter, hand-tightening it only.
• Add New Oil: Use a funnel to pour in new, high-mileage synthetic motor oil, ensuring it flows smoothly.

Step 4: Fog the Engine

To protect the cylinder walls, use fogging oil.

• Remove Spark Plugs: Take out the spark plug wires and the plugs.
• Inspect Spark Plugs: Check for cracks and ensure they are clean. Measure the gap using a spark plug gap tool.
• Apply Fogging Oil: Spray fogging oil into each cylinder for lubrication.

Step 5: Drain Old Gas

Old gasoline can cause starting issues.

• Remove Old Gas:
  • Use a hand pump and a hose to siphon out the old gas from the tank.
  • Ensure the hose reaches the bottom of the tank and is positioned lower than the tank to use gravity.
• Dispose of Old Gas Safely: Take it to a local recycling center or use it in a lawn mower if it's still usable.

Step 6: Check Coolant Levels

Ensure your cooling system is ready.

• Inspect Coolant: Look at the level in the reservoir and ensure it's filled to the indicated line.
• Test Coolant Condition: Use a hydrometer to check the coolant’s freeze protection level.

Step 7: Check Other Fluids

Other fluid levels are essential for vehicle operation.

• Power Steering Fluid: Ensure it’s within the minimum and maximum marks on the reservoir.
• Brake Fluid: Check that the fluid level is between the minimum and maximum lines.

Step 8: Start the Engine

Prepare to start the car safely.

• Get a Battery Jump: If the battery is dead, connect a portable jump starter.
• Attempt to Start: Turn the ignition and see if the engine starts.

Step 9: Troubleshoot Starting Issues

If the engine doesn’t start, consider these troubleshooting steps.

• Use Starter Fluid: If the engine cranks but doesn’t start, spray starter fluid into the air intake to check for fuel pump issues.

Conclusion

By following these steps, you can safely start a car that has been sitting for a long time without causing damage to the engine. Make sure to check all fluid levels, replace old oil and gas, and lubricate necessary components. If the engine fails to start, further diagnostics may be needed, especially regarding the fuel system. Happy driving!
