Tune-ups are a key factor contributing to maintaining your car in its original condition. But, how will you know when your car needs one? A tune-up is a preventative strategy to stop more serious problems from emerging over time. Is your car underperforming or losing gas mileage? Tune-ups include diagnostics checks that pinpoint the cause and correct underlying problems. Let’s look at the signs that it’s time for a car tune-up and what to expect.
Signs Your Car Needs a Tune-Up and What to Expect
Poor Fuel Efficiency
If your car shows a drop in fuel economy, then it’s time for a tune-up. If you fill up your tank more often than usual with no apparent change in driving habits, your engine may not be running efficiently. Worn spark plugs and dirty air filters increase fuel consumption and reduce mileage per tank.
Rough Idling or Stalling
If your car idles roughly or stalls, that’s a sure sign that there’s something wrong with your engine. Rough idling might be a result of dirty fuel injectors or an ignition system malfunction. If your vehicle stalls, this activity strongly points toward the motor being on its last legs and in dire need of tune-up services.
Difficulty Starting
Another warning sign that your car needs a tune-up is when it’s harder to start. A weak battery, failing starter, or ignition system problems may lead to the engine failing to start. A tune-up fixes the problem so the car starts reliably.
Unusual Noises
Knocking, pinging, or rattling emanating from the engine bay are red flags to tend to your vehicle. These issues indicate improper timing, misfiring, or problems with the exhaust system. A professional mechanic takes these noises into account during inspection, locating the source of the problem.
Warning Lights on the Dashboard
Modern-day cars come equipped with sensors that monitor a multitude of vehicle systems. If the check engine light illuminates on the dash, it’s indicative of something wrong with the vehicle’s motor. Newer cars often indicate when routine maintenance is needed.
Poor Acceleration or Performance
If the vehicle feels sluggish during acceleration it’s an indication that the engine is underperforming. Problems causing the issue include:
- Dirty fuel injectors
- Clogged air filter
- Faulty ignition system
A tune-up restores engine performance, making the vehicle responsive and efficient.
What to Expect from a Tune-Up
A tune-up involves a thorough check of your car’s engine and other key components. It’s a good idea to check your owner’s manual to determine the suggested time frame for routine maintenance. These small steps can save you from costly repairs later on.
The following list includes work you might expect to be done during a tune-up.
- Spark Plugs – The plugs ignite the fuel inside the engine. They wear out over time, resulting in misfiring and decreased performance. Checking and replacing spark plugs is a routine procedure in tune-ups.
- PCV Valve- The valve can be looked at for clogs or leaks. If the valve is bad, it can affect the performance and emissions of your vehicle. A sign of this is abnormal exhaust smoke.
- Air and Fuel Filter Replacement – The air and fuel filters keep contaminants from entering the engine. Clogged filters reduce engine efficiency and are replaced during a tune-up.
- Ignition System Check – Examination of the ignition coils and distributor cap for proper functioning and wear. Replacement of damaged parts to ensure normal engine operation.
- Fluid Check and Top-Off – All fluids are checked and topped off as necessary. This list includes engine oil, coolants, and transmission fluids.
- Battery Inspection – The technician checks the battery. They fill up the battery cells with distilled water or install a new battery if it’s dead. Batteries should be checked every 12 months or 12,000 miles.
- Belt and Hose Check – The mechanic inspects belts and hoses for signs of wear or damage like cracks, leaks, or frays. Replacement of these components prevents a more serious mechanical failure in the future.
At 100,000 miles, there are a few more items that may need to be addressed due to wear and tear, especially in older cars. This can include timing belts and hoses, fluid replacement, and engine coolant change.
Final Tips
Always ensure you get a written quote before booking your car for a tune-up to avoid hidden charges.
Regular car maintenance is key to keeping your car running smoothly. Always check your owner’s manual for suggested upkeep. Never ignore an indicator light on the dash.
