You probably don’t know this but your Volvo’s air filter is just as important as the engine. It is designed to combine both gasoline and air in the combustion chamber so as to create power for the car to move. So without the air filter, your car won’t move. Air first reaches the engine through the air filter whose work is also to prevent dust and debris from getting into the engine. It is more or less like a sieve which ensures fine air reaches the engine. With time though, the air filter gets clogged with dirt and other contaminants. This then goes on to affect your car’s performance. Fortunately, there are signs that can come in handy to help you determine when it’s time to clean the air filter.
Reduced Fuel Economy
Volvo engines always compensate for low amounts of oxygen by consuming more fuel so as to produce enough torque to move the vehicle. However, if you suddenly notice that gas mileage gets low every day, inspect the filter. This is especially the case with carbureted models manufactured before in the late 80s. Carburetors mix fuel and air to generate power for the car’s internal combustion engine. This means your car will end up consuming more fuel than it should any time the air filter clogs or develops a glitch. The best solution in this case is to replace the air filter with a new one.
This can be frustrating and annoying at the same time because your car will struggle to accelerate and pick up speed. It will also consume more fuel. This happens mostly because of a clogged air filter. Your car will respond to the problem with sudden jerking movements each time you try to accelerate. The jerking also happens because the engine fails to receive enough air for optimum performance. Cleaning or replacing the air filter should fix the problem.
Limited air supply from a dirty or clogged Volvo air filter will almost always result in frequent unburnt fuel coming off the engine as soot residue. It won’t be long before the residue accumulates on the spark plug. The accumulation will mean that the spark plugs will fail to provide the spark needed for combustion that should take place in the fuel and air mixture. The engine may start but it will then misfire roughly. In some cases, it won’t even start. This is by one of the most significant symptoms of a bad air filter. Again, the solution is to either clean it or have it replaced.
Replacing The Filter
Change your Volvo air filter after 10,000 to 15,000 miles or after every 12 months. Remember too that if you frequently drive in crowded areas, you will be forced to start and stop more often. This will without have a negative impact on your car’s air filter. It shouldn’t worry you though if you take your car for regular servicing where the air filter can be inspected and cleaned or even get replaced by a certified Volvo technician. Remember too that you shouldn’t allow an air filter problem to worsen by ignoring any of the aforementioned signs.
