Tuning-up your car can mean plenty of things. It’s a fantastic idea to look at the car’s ignition system and all filters, belts, hoses, and fluids. Many may not have to be replaced, but it is going to give you a opportunity to stop modest problems that could develop into big problems if left unattended. If you would like to know how to do some of the repairs listed below, consult one of our How-To guides. Should you want more detailed vehicle-specific info, check out our Repair Help diagrams and guides.

Have a look at the list below to discover the parts and systems which you ought to check at a tune-up. You don’t have to do all these things each time, but it is always a great idea to be certain that these are working correctly.

WHAT DOES A TUNE-UP CONSIST OF?
1
REPLACE PLUGS, WIRES, AND OTHER PARTS IN THE IGNITION SYSTEM
The ignition system includes spark plugs, plug wires, coils, and other electrical parts that spark the air/fuel mixture on your combustion chamber. The system has changed through the years. Some components have been replaced by computer controllers, therefore, some items listed below might not be included on your tune-up.

SPARK PLUGS
Spark plugs have a metal tip that wears down over time from high heat and high pressure.
A symptom of worn spark plugs is a misfire, once the fuel/air mix in a cylinder fails to ignite.
When replacing spark plugs, it’s highly suggested to use plugs of the original equipment (OE) advocated better or metal. Consult your owner’s manual, repair manual or the experts at AutoZone to find out which is the recommended spark plug metal is ideal for you.
Make certain to use a light application of anti-seize on the threads of the sticks before installation (prevent getting anti-seize anywhere else but the threads).
In DIS (distributorless) applications that utilize one coil for numerous plugs, make certain to use either Dual Platinum or Iridium plugs as recommended by the manufacturer.

IGNITION WIRES
Ignition cables will break down over time and finally fail.
Symptoms of a failed cable are demanding idle, performance reduction, and a dead cylinder.
When replacing a distributor cap or ignition wires, move 1 wire at a time in the old cap into the new cap. This prevents the ignition system from getting cross wired, which lead to a rough running engine. You can make this task easier by using a spark plug boot tool.
Use dielectric grease in the boots to help avoid arcing and make future boot removal easier.
Make certain your wires are protected and hauled away from exhaust parts.

IGNITION COILS
Coils transform low battery voltage into tens of thousands of volts. Over time this high voltage power wears out the coils out.
Signs your coils might be worn out include engine misfires, weakened acceleration, rough idle, and reduced gas mileage.
Some vehicles use coil packs, which are generally found close to the valve covers, while others use a coil-on-plug design that are over or near the spark plugs.
Put dielectric grease on the boot of coil-on-plug coils.
DISTRIBUTOR CAP AND ROTOR (IF APPLICABLE)
Numerous rotations of the rotor within the distributor will get the metal contact point to wear down.
A failed distributor cap causes misfires or in more severe cases a non-start.
When doing a tune-up it’s advised to replace both the cap and rotor in exactly the exact same time.
Transfer ignition wires one at a time from the old cap into the new cap. This prevents the ignition system from getting cross wired, which lead to a rough running engine. You can make this task easier by using a spark plug boot tool.
Two
LET YOUR ENGINE RUN CLEAN WITH NEW FILTERS
Filters on your automobile consist of: gas, oil, air, and cabin air filters. Filters keep contaminating particles from reaching vital components in your engine and related systems. Having a clean filter enhances engine performance and efficiency. Dirty filters make your vehicle work harder to find the airgas, and oil it needs. This can choke your engine off or reduce the capacity to deliver air, gas or oil at the right pressure.

ENGINE AIR FILTER
Filters thousands of gallons of air for each gallon of fuel and will clog over time.
Clogged air filters can decrease performance, but not MPGs on fuel injected engines.
Clogged air filters in carbureted engines may decrease MPG’s by 2-6% and up to 14%*.
Replacing your air filter is usually a simple task, have a look at our air filter replacement manual if you need help.

CABIN AIR FILTER
Some vehicles are equipped with a cabin air filtration system and so have a replaceable filter element to keep the air in the vehicle clean.
A filthy cabin air filter can allow dust, pollen, exhaust fumes and other contaminants in your car’s passenger compartment and restrict airflow to the automobile.
Most cabin air filters are easily available and require less than 15 minutes to change. Find out how from this cabin air filter manual.

OIL FILTER
Dirty oil may result in excessive wear on internal engine parts.
An oil filter is used to filter vital engine oil of contamination and may clog if not replaced at recommended intervals.
May lead to high oil pressure in acute conditions of clogging.
Should be replaced with each oil change at recommended intervals. Learn more from this manual

FUEL FILTER
Dirty gas and contaminated gas tanks can clog your fuel filter and result in low fuel pressure, occasionally leading to hesitation when speeding or rough idling.
May lead to premature fuel pump failure in acute conditions.
Should be replaced with each oil change at recommended intervals.

PCV VALVE
Over time the Positive Crankcase Ventilation Valve can get obstructed by carbon build up.
Failure can cause the engine to run rich or absorb oil because of the increased crankcase vacuum.
The PCV Valve is generally easy to replace. Oftentimes, it can be performed in a matter of a couple of minutes.

KEEP YOUR AUXILIARY SYSTEMS IN CHECK WITH NEW BELTS AND HOSES
Belts join the pulleys of your accessory drive system that transfer the rotating power of the crankshaft pulley to the alternator, water pump, power steering pump, and other systems. Hoses transfer vital fluids throughout the engine. As time passes, belts and hoses wear due to the elements they’re exposed to such as heat and cold and the continuous use they see daily to day functioning of the automobile. They eventually wear down, glaze over, turn brittle, crack and even break.

SERPENTINE BELT
The serpentine belt rides in a set of pulleys on the front of your motor.
The belt wears down, and requires replacement due to exposure to stress and heat.
Inspect the belt(s) for cracks, fraying, glazing or fluid contamination. Any of these conditions can cause the belt to slip or break.
If you need assistance changing the belt out, take a look at serpentine belt replacement manual.

BELT TENSIONER
The belt tensioner maintains the right belt tension.
A feeble belt tensioner can cause premature belt wear.
A’tight or sticking’ belt tensioner can cause premature wear to the water pump and other attachment bearings.
With the belt off, rotate the tensioner through its arc of travel. It should move smoothly and offer firm tension.
While the belt is off check the idler and accessory pulleys for proper alignment and smooth rotation.
TIMING BELT
The timing belt controls the inner mechanical timing of the parts that keep your vehicle running correctly.
When a timing belt breaks on a few vehicles, the piston can come in touch with valves which are stuck open that causes catastrophic damage.
The timing belt is an intricate job, and needs to be replaced on the recommended mileage periods.
When inspecting your timing belt, take some time to inspect the cam and crank seals for leaks.
Some vehicles feature a timing chain rather than a timing belt. Timing chains typically don’t have to be replaced.

HOSES
Radiator hoses and heater hoses circulate coolant through the engine and the radiator to expel the heat consumed.
Most hoses are made from rubber and will break down with time. You may find out of it’s time to replace your hoses by scrutinizing them for swelling, bulging, or escapes. When the engine is cool, squeeze the hoses to feel for tough spots and soft spots.
Check the hose clamps for loss or damage of tension too. You do not want one to go while your engine’s hot
If a hose were to fail, the engine could overheat. Overheating can cause severe, sometimes irreparable damage to the motor.

MAINTAIN YOUR CAR’S COMPONENTS WITH THE RIGHT FLUIDS
Engine oil, coolant, brake fluid, transmission fluid, and power steering fluid are essential for your vehicle to function correctly. Contaminated fluids may result in excessive wear on internal parts. You may save money in the future by servicing those fluids before costly damage happens. Normal change intervals exist for every type of fluid and therefore, they have to be replaced at recommended service intervals, learn more by consulting your owner’s manual or by seeing MyZone.

MOTOR OIL
As oil circulates through your motor and is subjected to heat and pressure, the oil will get contaminated.
An oil filter will keep large particles from being recirculated, but won’t keep the oil from providing a protective barrier of lubrication.
Replace the oil filter during an oil change.
Oil ought to be replaced at manufacturer recommended mileage or time periods, consult your owner’s manual or call Mobile Mechanic Mesa for additional information.

COOLANT
Your heating system keeps your motor from overheating in the summer and prevents your own engine from freezing in the winter.
Coolant will eventually break down and become infected which results in blood circulation that contributes to a decrease in the ability to protect your engine.
Flushing your heating system using a flush product specifically designed to remove deposits every 2 years will enhance the performance of your cooling system.
Always refer to your owner’s manual to ascertain the recommended coolant for your car or truck. Various manufacturers require using different kinds of coolant and employing a fluid other than what’s given by the manufacturer could lead to engine damage.
Make certain to combine the coolant with the suitable quantity of water or use a pre-mixed product that’s ready to pour in.
If You decide to change your coolant, check out our coolant flush and fill manual

BRAKE FLUID
Brake fluid is a crucial fluid in your car or truck, without it you wouldn’t have the ability to stop.
DOT 3 and DOT 4 brake fluid are hygroscopic, so the fluid will absorb moisture in the atmosphere. This extra moisture enhances the fluids ability to function effectively as a hydraulic fluid.
Dark or muddy looking fluid is a certain indication of hygroscopic contamination.
It’s suggested that the brake fluid be changed out for new fluid and the brake system bled to make sure that fresh clean fluid is flowing through the whole system.
Two years is the recommended changing period. Find out how to do it yourself with our guide on the best way best to bleed brakes.

AUTOMATIC TRANSMISSION FLUIDS (ATF)
Constant gear changing within the transmission results in wear of internal contamination and components of transmission fluid. This wear and tear makes it imperative to follow manufacturer’s recommendation for transmission filter and fluid change.
Brown transmission fluid is an indication that the fluid has to be changed however, if the fluid is muddy, do NOT alter, rather, take your vehicle to a professional for a professional diagnosis.
Make certain to log into MyZone or consult your owner’s manual for recommended change intervals in addition to the right fluid type for use.
POWER STEERING FLUID
Over time contamination may cause wear to the power steering pump.
Be certain that your power steering fluid doesn’t appear muddy and is between the MAX and MIN levels in the reservoir.
Make certain to log into MyZone or consult your owner’s manual for recommended change intervals in addition to the right fluid type for use.

You can get terrific benefits from doing a tune-up on your car or truck. It’s among the best ways to keep original performance. In actuality, fixing a car that’s badly out of tune can give a noticeable increase to both engine performance and fuel economy*. A vehicle running in top shape now prevents and reduces costly repairs tomorrow. AutoZone’s tune-up manual will show you the common parts that are replaced when trimming up a car such as spark plugs, plug wires, air filter and fuel filter. It’s also a wonderful time to check different parts under the hood including belts, hoses and fluids.
