A regular car tune-up can prevent a wide range of common—and expensive—vehicle problems. Though a regular tune-up can be easy to overlook, make sure you take in your car for a thorough checkup every two years or 30,000 miles (whichever comes first). Why is this maintenance check so important and what happens during one? Read on to find out, and check out our auto tune-up services for more details on Colorado auto repair.

When you bring your vehicle in for a car tune-up, one of the first things checked and probably replaced is your fuel filter. After thousands of miles, the filter is likely clogged and replacing it is a must. Your spark plugs are then replaced (unless they’re platinum), and the spark plug wires are examined and may be replaced. If your car is older, the distributor cap and rotor may be replaced. Another tune-up for older cars (those without electronic ignition) would be changing out your points and condenser, but few cars made after the eighties will require this.

Next, your car’s valves will be adjusted as needed. The valve-cover gasket will also be replaced. One of the main things your mechanic will be sure to hit is checking the belts in your car and replacing them if they’re worn down—worn belts can cause serious engine damage as well as a host of other problems.

Basic checks will also be performed, such as checking all your under-the-hood fluids and replacing them if necessary. If it’s been 3,000 miles or more since your last oil change, your oil and oil filter will also be replaced. The air filter will also be changed out if it’s about 15,000 miles old. If your car has a manual transmission, the clutch may be adjusted. The battery will also be checked and cleaned. Finally, the positive crankcase ventilation (PVC) valve will be replaced. When clogged, it can make your car run badly or have trouble starting.

Taking your car in for regular tune-ups is more than just running through a laundry list of potential problems. It can mean the difference between a prohibitively expensive breakdown and your car running smoothly for years to come. While this regular maintenance check isn’t a cure-all for major car maladies, it makes it much more likely that your mechanic will see a potential problem before it causes permanent damage.
