How Often Does Your Car Need A Tune Up?

November 12th, 2020 by

Your car needs regular oil changes, we all know, but when does a tune-up take place? Every 30,000-45,000 miles, a tune-up was needed in older cars. Modern cars do not need a tune-up in the traditional sense, Tune-upTune-up time: a set of spark plugs and wires for a V6 engine, an air filter and a spark plug socket with a ratchet, because there is nothing that can be adjusted and everything is controlled by a computer.

For modern cars, “tune-up” is a major service that involves oil change, engine air filter replacement spark plugs, and probably a few additional products. A tune-up is usually recommended if the car starts to run poorly (scroll down for symptoms) or if your spark plugs are due to be replaced according to the maintenance schedule.

Spark plugs provide an electric spark to start the combustion of your engine, so if the spark plugs are broken or worn out, your engine won’t run properly.

Conventional spark plugs must be replaced every 30,000-50,000 miles. Iridium-or platinum-tipped spark plugs can last 50,000-120,000 miles.

The gas filter used to be a major part of the tune-up. Thanks to improved technology and fuel performance, the replacement of fuel filters in most modern cars is not needed. Also, the maintenance schedule will inform you if it ever needs to be replaced. For example, if you have the 2009 Ford Mustang, you will change the fuel filter every 30,000 miles in accordance with the maintenance schedule. However, there is no mention of the fuel filter in the Toyota Camry 2019 maintenance schedule.

Likewise, for the 2017 Honda Accord and 2018 Mazda 3, the fuel filter is not even specified. Nissan’s 2010 Service and Maintenance Guide notes that “Fuel Filter is a maintenance-free product (in-tank style filter).” The main symptom of a dirty fuel filter is a lack of acceleration or uphill energy. Replacing a fuel filter, if mounted outside the tank, will cost from $90 to $160.

Diesel cars are fitted with a Diesel Fuel FilterDiesel fuel filter, Volkswagen Jetta TDI.fuel filter has a water separator. Each 10,000 miles or earlier, the water separator needs to be drained. Replacement intervals are different. For example, the maintenance schedule for the 2017 Audi model year recommends replacing the TDI diesel fuel filter every 20,000 miles.

The air filter is the one thing that must certainly be replaced during the tune-up. The main function of an air filter is to prevent dust and sand from reaching the engine and damaging the walls of the cylinder. It is recommended that an air filter be replaced every 15,000-30,000 miles or earlier if you often travel on unpaved or dusty roads.

When the air filter is extremely dirty, it strains your engine–remember how the vacuum sounds when something closes it up? Air Filter Replacement of an air filter. Replacement of an air filter is not very expensive ($25-$90) and is an easy project for any DIY car enthusiast. When you replace an air filter, the engine can “breathe” easier.

What else might need to be replaced or adjusted during the tune-up? Often in high-mileage vehicles, the throttle body may become dirty, with carbon deposits preventing the throttle valve from functioning properly. This issue could lead to a rough idle, stalling, and your “Check Engine” light could come on as a result. Your mechanic may recommend that you clean the throttle body as part of a tune-up.

The fuel induction service is another frequently suggested tune-up item. A mechanic sprays a special cleaning solution or foam into the intake manifold to perform this operation. The main objective is to clean the carbon deposits on the intake valves and pistons, which may cause problems in high-mileage direct fuel injection engines. Manufacturers do not include this type of service in the recommended maintenance. This service is more beneficial to problems in high-mileage engines; if your car is good on gas and runs fine, you won’t see much improvement. The cost may range from $90 to $180.

If your battery is getting weaker and it’s been a while since you replaced it last time, your mechanic may recommend that it be tested. Normally, a mechanic may run the check of your battery and charging device, and if the battery capacity is small, he or she may suggest replacing it.

If your car has low gas mileage, your mechanic may suggest replacing the front oxygen sensor (or both V6 and V8). The oxygen sensor is one of the main components responsible for the quantity of fuel used by the engine. Of course, if your car is running fine and your “Check Engine” light isn’t on, you don’t really need it. Normally, an oxygen sensor is not required to be replaced as part of the scheduled maintenance.

If your car has a timing belt, it will also often be replaced during a major tune-up. Not all cars have a timing belt; instead, many newer cars have a maintenance-free timing chain. If your car has a timing belt, it will be indicated in the maintenance schedule. Or your drive belt (serpentine belt) hasn’t changed in a while, it might also be recommended to replace it during a tune-up. The drive belt runs engine accessories and is usually replaced every 40,000 to 70,000 miles.
