What Does a Car Tune Up Include?

A car tune-up is similar to a regular checkup from a doctor. You can check the overall condition of your vehicle to keep the parts in order. The process involves servicing to ensure that you get maximum productivity. Tuning up the vehicle not only maximize engine performance but also improves fuel efficiency. Defining a tune-up in words is very hard as there isn’t a conclusive definition. Some even consider performing a Mini Cooper S R56 Remap as a tune-up.

So, what exactly is a tune-up for a car or vehicle? There are some small checkups that are considered essential. These are the inspections that a mechanic usually performs during a tune-up.

Checks for a Car Tune Up

According to experts, a tune-up is just about replacing the cabin air filter and installing new spark plugs. We have enlisted a few checks that mechanics often include in a tune-up.

1.Essential Tune-Up Checks

Battery check is the most essential part when you take your car for servicing or tune-up. Here are some assessments that are considered important.

2. Battery voltage

It includes inspecting and charging the voltage of the battery. This is a necessary check as modern vehicles are loaded with electronics.

3. Power Balance

Dynamic compression is a more relevant word for this checkup. It involves inspecting any mechanical glitches in your car. Such as bad cam, bad head gasket, worn rings, leaky exhaust valves, etc. These are the issues that may affect engine performance and compression.

4. Engine Vacuum

It involves an inspection of the exhaust system and detecting any air leaks. Reviewing the control loop is also included in this checkup.

5. Scanning Faulty Codes

This includes eliminating the faulty codes and verifying that there is no defective code. The exhaust emissions inspection is another check to ensure that a vehicle is roadworthy. Emission, ignition and gross fuel problems are detected during the checkup.

6.Ignition Timing

It includes an inspection of the EGR valve to detect any potential issue.

7.Verifying the Idle Speed

On new vehicles, injector dwell is tested to verify fuel control feedback. Whereas in older vehicles with carbureted engines, the idle mixture is checked.

Necessary Replacements

In case there is no major defect in your vehicle, you should check for necessary replacements. These replacements are a part of preventive maintenance to save your vehicle from a major fault.

1. Spark Plugs

Of course, spark plugs are the first car part that you should check. Replace the plugs if they are outdated or creating a problem.

2. Inspection and Adjustment

Do an inspection on O2 sensor(s), idle mixture and adjust idle speed as well as ignition timing.

3. Filters

Checking on your vehicle filters is important during a tune-up. See if air filter fuel filter and breather filters need a replacement.

Checking Other Stuff

Cleaning the intake system and fuel injectors is also part of a tune-up. However, redesigned injectors and upgraded fuel additives have pretty much solved the injector cleaning task. Another issue is a fuel varnish deposit that often forms in the injectors. Such deposits limit the fuel amount and ultimately affect the air/fuel mixture. Deposits on intake valves can also create cold hesitation problems.

Last Words

Taking your car for servicing is a great way to keep it functional. Regular maintenance also extends the lifespan of your automobile. But asking a mechanic to tune up your car is not a good way to ask for service. It shows that you are still using the old dictionary in the modern age. The mechanic may cost you extra because he’ll assume that you don’t know much about automobiles.
