As a car owner in California, it can often be stressful and nerve-racking when you have an upcoming smog check inspection to prepare for in the coming weeks or months.
The results of the smog check test determine if you can register your vehicle with the California DMV and continue driving it to get around.
Fortunately, there are a few ways you can pass a California smog check inspection to ensure your car doesn’t release too many emissions and will continue to be legally drivable.
Don’t Disconnect the Battery
Many people don’t realize that disconnecting their battery causes the car’s computers to wipe clean, which can affect the results of the smog test.
Avoid scheduling any maintenance or repairs two weeks before the scheduled smog check to prevent the computers from losing their data.
If your battery dies and you have to jumpstart it or even replace it with a new battery, push back your smog check to prevent it from affecting the test performed on the vehicle.
Schedule a Pre-inspection
A great way to determine how your vehicle will perform during a smog test is to schedule a pre-inspection with a local mechanic in advance.
Sell or Donate Your Junk Car In California:
Sell or donate your junk, damaged or totaled car. You will get paid on the spot when your car is towed at no cost to you.
Choose the location nearest you:
- Chula Vista
- Daly City
- El Cajon
- Los Angeles
- Redwood City
- San Diego
- San Marcos
- Santa Cruz
- San Francisco-Oakland
- San Jose
- Walnut Creek
Visit a California smog check facility to get the same type of tests several months or weeks in advance to determine if any issues are present.
Scheduling this test in advance will allow you to have the time to perform the necessary repairs and improve the condition and operation of the vehicle.
Get the Oil Changed
One of the best steps to take when preparing for a California smog test is to get the oil changed to ensure the oil is clean when you take it into the facility.
Dirty oil that has contact with the different parts of your engine means more contaminants are present, which can make it easy to fail the test.
Adding new oil will reduce the number of hydrocarbons that are present.
During the oil change, you can also ask the mechanic to perform a quick inspection of the hoses to determine if anything is broken, cracked, or disconnected.
Broken hoses that need to be replaced are one of the many reasons cars fail smog tests.
Add fuel additives to your gas tank, which will be effective in reducing the emissions that are present and helping the car pass the inspection.
Pour the additives into the fuel tank while also filling it up with gas to increase the changes of passing the smog check.
You can also add more coolant to the vehicle, which will prevent too much vapor from entering the fuel line while using the vehicle. Putting more fuel into the tank will also protect the fuel line.
Address the Check Engine Light
It can be easy to assume your check engine light is illuminated by mistake or for a minor issue, but the light should be addressed before the smog test.
A check engine light will immediately make the car fail the test and can indicate a serious issue is present under the hood.
If you’re unable to discover the problem yourself, hire a technician to perform an inspection to ensure the necessary repairs are made.
Perform the Necessary Repairs
It’s easy to put off certain repairs that are needed on your vehicle, but this can affect the operation of your vehicle and lead to too many emissions as it runs.
Schedule the repairs in advance to make the car drive better and place less strain on the engine if certain parts aren’t operating as efficiently.
Inflate the Tires
Your tires can lose air as you spend time on the road or if leaks are present, which can affect how well the car drives at low and high speeds.
It’s important to inflate the tires with more air after checking the PSI to ensure your vehicle is more fuel-efficient.
It’s also important that the engine parts don’t work harder than necessary to operate when the tires are low on air, which can put unnecessary strain on the parts.
Inflating the tires will allow the car to run better during the smog check.
You can also have a technician inspect each tire to determine if they have even tread or if leaks are present for improved operation.
Drive Around at Higher Speeds
Get in the habit of driving faster for two weeks before the test is scheduled.
Opt for taking the highway as much as possible instead of side streets, which will allow the car’s catalytic converter to convert different pollutants into less harmful emissions.
This part needs to reach a hot temperature to convert the pollutants, which requires driving faster than normal to prepare your vehicle for the smog check. It will also work well for burning off gas residues and oil that is present before your smog inspection.
Schedule a Tune-up
Schedule a tune-up before your smog test a few weeks in advance to ensure the engine is in tip-top shape.
Avoid performing this service right before the smog test because it involves disconnecting the battery. The test should be performed enough in advance to ensure you have time to drive 100 to 200 miles before the test is performed after the data is reset on the computers.
Passing a smog check can be harder than you think if your car isn’t in excellent condition and hasn’t undergone a recent inspection.
There may be minor issues that are easy to overlook that can set the car up for failure, which can lead to costly fees and difficulty getting around if you’re unable to get it registered.
Taking the necessary steps to pass a California smog check will allow you to feel more prepared and at ease.
