What Does Mackeyboys
Tune-up Consist of?

1. Replace Plugs, Wires, and Other Ignition Parts

The ignition system includes spark plugs, plug wires, coils, and other components that ignite the air/fuel mixture in the combustion chamber. Modern systems require changing spark plugs and wires/coil boots at specific mileage intervals, while older systems may have additional parts like a distributor cap and rotor, or breaker points.

Spark Plugs

  • Over time, the metal tip (electrode) of spark plugs gradually wears down due to the combination of intense heat and continuous electrical arcing.
  • When spark plugs become worn, a common indication is a misfire, which occurs when the fuel/air mixture in a cylinder fails to ignite.
For distributorless ignition systems (DIS) where one coil is used for multiple plugs, it is crucial to follow the manufacturer's recommendation and use either Double Platinum or Iridium plugs.

Ignition Wires

  • Signs of a malfunctioning wire include rough idling, frequent misfires, decreased performance, and ultimately, the loss of power in a cylinder.
  • Over time, ignition wires deteriorate and eventually reach a point of failure.

Ignition Coils

  • Continuous exposure to high voltage electricity gradually deteriorates the performance of ignition coils over time.
  • Common indicators of worn-out ignition coils include engine misfires, decreased acceleration, rough idling, and diminished fuel efficiency.

Distributor Cap, Rotor, and Breaker Points (if applicable)

  • A malfunctioning distributor cap can lead to misfires or, in severe cases, prevent the engine from starting.
  • Repeated rotations of the distributor rotor result in gradual wear of the metal contact point.

2. Ensure a Clean Engine with Fresh Filters

Your vehicle relies on various filters, including oil, fuel, air, and cabin air filters, to prevent harmful particles from reaching critical engine components. By maintaining clean filters, you enhance engine performance and efficiency. Conversely, dirty filters can strain your engine and impede the delivery of essential air, fuel, or oil at optimal pressure. Ensure your filters are clean to keep your vehicle running smoothly.

Engine Air Filter

  • Filters process ample air compared to fuel but can clog over time.
  • Clogged air filters can impact performance but have no effect on fuel efficiency in fuel-injected engines*.

Cabin Air Filter

  • Certain vehicles come equipped with a cabin air filtration system, featuring a replaceable filter element to maintain clean air quality within the vehicle.
  • A clogged cabin air filter can permit dust, pollen, exhaust fumes, and other pollutants to enter the passenger compartment of your vehicle and impede the airflow.

Fuel Filter

  • Contaminated fuel and fuel tanks can cause fuel filter blockage, leading to reduced fuel pressure and potential issues like hesitation during acceleration or rough idling.
  • In more severe cases, this can result in premature failure of the fuel pump.

PCV Valve

  • Carbon build-up over time can cause the Positive Crankcase Ventilation (PCV) Valve to become clogged.
  • When the PCV Valve fails, it can result in increased oil consumption, poor fueling conditions, misfires, and potential gasket blowouts due to excessive pressure in the crankcase.

3. Ensure Optimal Performance of Auxiliary Systems with Fresh Belts and Hoses

Belts play a crucial role in transferring power from the crankshaft pulley to various accessory systems, while hoses ensure the proper flow of fluids throughout the engine. However, constant exposure to heat, cold, and regular use causes belts and hoses to deteriorate over time. Eventually, they become worn, brittle, cracked, and may even break, compromising the performance and reliability of your vehicle.

Serpentine Belt

  • The serpentine belt loops around a set of pulleys located at the front of your engine.
  • Due to exposure to heat and constant stress, the belt undergoes wear and tear, requiring replacement.

Belt Tensioner

  • The belt tensioner ensures optimal tension of the belt.
  • Insufficient belt tension caused by a weak tensioner can lead to premature belt deterioration.

Timing Belt

  • The timing belt is responsible for regulating the internal mechanical timing of many engines. Typically, this belt has a lifespan of around 80,000 to 100,000 miles before it needs to be replaced, along with any accompanying tensioner or idler components.
  • In the event of a timing belt failure in most vehicles, it can result in contact between the piston and the valves that may be in an open position, leading to severe and irreversible engine damage.

Hoses

  • Radiator hoses and heater hoses play a crucial role in the engine’s cooling system, circulating coolant to dissipate the heat absorbed by the engine and radiator.
  • Over time, rubber hoses can deteriorate, leading to potential issues. Regular inspection of your hoses is important to check for signs of deterioration such as swelling, bulging, leaks, or irregularities in texture. Squeezing the hoses when the engine is cool can help identify any areas that feel excessively hard or soft, indicating the need for replacement.
