Saturn Vue Air Filter
Determining if Your Saturn Vue Air Filter is Dirty
The engine is placed in a secured compartment in your vehicle, but what actually keeps it safe from even the tiniest dirt particles is the air filter. As its name implies, the air filter is a device responsible for sifting the air that enters the engine. It traps dust and road debris, thus preventing any of these substances from damaging your engine. However, an air filter is meant to fail eventually. The following are signs, which would help you determine a dirty air filter:
Dark smoke in the exhaust
If the smoke coming out of your exhaust is too dark, there is a high probability that you have a plugged air filter. This black, soot-like residue is actually the result of a rich fuel mixture, which means that there is less oxygen and more fuel being used during combustion. Also, you may detect a strong smell of gasoline accompanying this dark smoke. Usually, it becomes noticeable the moment you start your engine. These impurities in your exhaust pipe can be rooted from a dirty air filter. Inspect your Saturn Vue air filter and replace it when there is already a significant accumulation of dirt on it.
Heard a bang from the back of your vehicle? That sound could mean that your engine has backfired. Check your exhaust pipe and prepare yourself for the possibility of seeing a flame at its end. Engine backfiring is another consequence of a dirty air filter, which is incapable of allowing an adequate amount of air into the engine. Thus, a rich fuel mixture comes about. However, sometimes, there is only a little amount of fuel present, which is referred to as a lean misfire. You need to replace your air filter as soon as possible so that dirt particles won't interfere with the smooth passage of air.
Listen in closely for a rough noise coming from the engine. Although it may be caused by so many possible reasons, it would be worth checking your air filter. A plugged air filter could be the culprit behind the black residue on the spark plug, which prevents the plug from firing. This defect then leads to the rough engine noise you hear. Replace the air filter to avoid damaging other components, too.
