To keep your vehicle performing at its best, you need to perform periodic tune-ups. Older model cars may require replacing caps and rotors but most modern tune-ups involve replacing spark plugs, plug wires, 02 sensors (some vehicles have more than one) and fuel filters. Materials: Spark plugs and wires
Fuel filter
02 sensor
Torque wrench fitted with an 02 sensor socket
Canned air
Spark-plug gauge
Anti-seize lubricant
Socket wrench
Ramps
Wheel chocks
Safety glasses - Before getting started, consult your owner's manual for the recommended maintenance schedule for changing your vehicle's spark plugs. It's important to change the entire set of plugs at one at a time. Remove and install each plug (figure A) before moving on to the next.
Note: Use anti-seize lubricant when installing new spark plugs. - When installing new plugs be sure to set the recommended gap, maintain the proper firing order and "never" over tighten a plug.
- Since plugs work together with spark-plug wires, it's important to change the wires (figure B) at the same time.
Note: Use tape or a clothes pin to keep the wires in the correct firing order. Gap and replace one plug at a time to ensure the correct order is maintained and use a torque wrench to tighten the new plugs so you don't crack the porcelain. Apply anti-seize lubricant to the threads of the new plugs, if required, so it's easier to remove the next time you replace the plugs. - To keep a free-flowing fuel line, replace your fuel filter every 12,000 miles. First, release the pressure in the fuel line. If you have a fuel-injected vehicle, be sure to release the pressure in your fuel line "prior" to changing the fuel filter.
Turn the engine off, disable your fuel pump either at the fuel pump turnoff switch or by pulling the fuse to your fuel pump. Then start your vehicle. It won't run long, but it will relieve the pressure. - Then locate the fuel filter. Disconnect the fuel line as recommended and install the new one -- being sure the arrow that indicates fuel flow is pointed in the right direction.
Note: Some vehicles come equipped with a Schrader valve to release the pressure. Vehicles vary, of course, so be sure to check your owner's manual for instructions on replacing your fuel filter. - Finally, using a torque wrench fitted with an 02 sensor socket, remove the 02 sensor (figure C) located along side the exhaust manifold and replace.
- Your vehicle may have more than one 02 sensor, so be sure to replace them all.
Spending a little time and money on your vehicle now could save your from breakdowns and big repair bills down the road.
