If you have a smog check in your future, you might wonder what you can do to ensure that you pass. After all, each test costs money, and failure to pass could make it more difficult for you to register your vehicle.

So, should you get service on your car to ensure you can pass a smog test? It may be a good idea. Here's what you should know.

Make Sure Nothing Is Setting Off Your "Check Engine" Light

One of the most important things to know about your car's smog test is that the "Check Engine" light cannot be on. If the light is on, your vehicle will automatically fail the test. This means that you need to make sure your car is serviced if the light is on. Talk to the professionals about ensuring it does not come back on before your test.

Top Up on Fluids (Coolant & Gas)

Your vehicle also needs to have enough coolant to pass the test. A mechanic at an auto service center can ensure that your vehicle has all the coolant it needs. Likewise, also make sure that the vehicle has enough gas before your smog test. You might even use a fuel additive if your car might benefit from it. A mechanic can tell you if this is a good idea.

Change the Oil

Changing the oil can help get rid of some of the pollutants that your car puts out. It is a good idea to bring your car in for an oil change if your car needs it. This also gives a mechanic a good opportunity to check for other potential problems, like cracks and debris under the hood.

Get a Tune-Up

A tune-up will help your car run at its best for your smog test. Make sure that you don't get a tune-up right before the test. Rather make sure that you come in for auto service about two to three weeks before the test so you can get plenty of driving in to get the necessary diagnostics in place.

Car Service Can Help

Getting your vehicle serviced may be the best option for you. If you are trying to pass a smog test, you need to consult with an auto service professional to get your car in great shape. A local car service can help your car run at its best so that it is sure to pass the test before registration.
