How Much Does a Buick Tune Up Cost?

One of the most frequently asked questions is how much a tune-up on a Buick costs, or what is the average price for a complete tune-up. The answer varies between $150 and $400, depending on what the tune-up includes. A complete tune-up includes several tasks, and not all are performed at the same time.

Sometimes, a tune-up may also be performed at the same time as a routine service of an engine oil and filter change, which is why many people confuse a tune-up with a standard service. They are not the same, but performing both at the same time saves time and money, plus ensures that your Buick is in peak condition. However, you won’t need to complete a tune-up at every routine service.

What’s Done During A Routine Servicing Of My Buick?

A routine servicing of your Buick will include a check of all its critical systems, a change of engine oil and filter, inspection of the undercarriage, tires, brakes, and body condition, and greasing relevant points. A routine service on a Buick may cost between $50 and $200 depending on what’s done and where you choose to do it.

What Does A Full Tune-Up Consist Of?

A full tune-up is rather more involved, and some tasks vary if you’ve got a classic or modern Buick. Let’s have a look.

  • A classic Buick with a carburetor-fed engine will see its carburetor checked, cleaned, and worn-out parts replaced with a carburetor repair kit. The air filter atop the carb will be cleaned, and the carb adjusted. This is particularly difficult if your Buick uses dual carburetors, as balancing these is a dying art. The fuel pump and lines will be checked, and the fuel filter may be replaced.
  • If you’ve got a contemporary Buick with electronic fuel injection, the injectors and fuel rail will be removed and cleaned, and injectors checked for spray pattern post-cleaning. The fuel lines and pump will be checked too, and the filter will be replaced. Your Buick’s air filter, intake manifold, and throttle body will be checked and cleaned too, and the air filter may be replaced.
  • If your Buick uses a distributor-based ignition system, this will be checked and worn-out parts replaced, including the distributor cap, contact breaker points, high tension wires, condenser, and spark plugs.
  • If your Buick is a modern one with coil-on plug ignition, spark plugs may be changed, and coil packs tested for functionality.
  • The sensors on modern Buicks may be removed, cleaned, and checked.
  • An OBD scan will be conducted on modern Buicks with OBD compatibility to detect issues.
  • The engine cooling system will see a coolant flush and replenishment with fresh coolant.
  • Brakes may be bled and refilled with fresh brake fluid.
  • The power steering system will be checked and power steering fluid replenished if necessary.
  • The PCV (Positive Crankcase Ventilation) valve and system will be checked and cleaned.
  • Accessory belts and belt tensioners are visually inspected and replaced if necessary.
  • The battery and electrical system are inspected for damage and wear.

How Often Should My Buick Receive A Tune-Up?

A typical Buick requires a routine service every 5,000 miles, or six months, whichever occurs first. This does not include most of the tasks of a tune-up, although the air filter may be checked as well. Not all tune-up activities have the same service interval.

  • Spark plug change intervals may occur every 100,000 miles.
  • The fuel filter may require changing every 25,000 miles, and the injectors are cleaned around the same time.
  • The engine air filter may require changing every 15,000 to 30,000 miles, depending on driving conditions.
  • The intake manifold, throttle body, and intake piping may require cleaning every 20,000 miles.
  • An OBD scan may be performed at every routine service, and errors rectified based on the detection.

Your best avenue to ensure that your Buick doesn’t miss a tune-up is to obtain a copy of your model-specific maintenance schedule from a Buick dealer and follow it.

What Are The Signs That My Buick Needs A Tune-Up?

There are many signs that your Buick may require a tune-up. These include:

  • Your Buick’s engine doesn’t make as much power as before, and performance is down.
  • Your gas mileage has gotten significantly worse.
  • Your Buick’s engine feels rough, shudders, shakes or vibrates unusually.
  • You are seeing a Check Engine light illuminating in your dash.
  • Something feels off in your Buick when you drive it.

Does A Tune-Up Make My Buick Run Better?

Tune-ups make every vehicle run better, as you’re effectively cleaning, rejuvenating, and replacing things to as near factory condition as possible. Some of the benefits of a tune-up include:

  • Your engine feels more powerful, as it’s now working closer to its optimal output.
  • Your gas mileage is better.
  • Your engine, and vehicle drive and run smoother.
  • You don’t need to worry about your Buick letting you down.

What are the differences between a service and a tune-up?

A service covers fewer points, while a tune-up will be more intensive maintenance of your Buick’s engine and related systems to keep it operating well.
