Subaru Engine Diagnostics: Visit Your Subaru Dealership

Engine diagnostics are an essential part of vehicle maintenance. When you have your Subaru serviced, our highly-trained mechanics use a diagnostic tool to assess the engine’s condition. The device pinpoints the root cause of the problem using the vehicle’s integrated computer system, which monitors routine processes. Our team can then fix the issue and send you on your way as quickly as possible. Visit your Los Angeles Subaru dealership if you notice these warning signs.

 

Reduced Fuel Efficiency

Your Subaru will consume more fuel than usual when the engine experiences wear and tear. Reduced fuel efficiency is often due to low fuel pressure or a lack of oil. When the fuel fails to reach the correct psi, the engine burns more fuel to produce the same amount of power. Oil pressurizes the fuel and lubricates parts to withstand the added pressure. Low or contaminated oil levels make it harder for the engine to burn, increasing the mpg rating.
 
Monitor your fuel consumption compared to the EPA-estimated mpg rating to see if your vehicle needs a tune-up. An inspection will save you money on fuel.

Poor Acceleration

If your vehicle struggles to accelerate, the engine may not be getting enough air. A clog could be preventing fuel from reaching the injectors. Leaks and broken injector heads also prevent fuel from entering the combustion chamber. Parts often break down from a lack of oil. The engine may also be overheating due to a lack of coolant or radiator trouble, which causes the fuel to burn off before it can be put to work.

There may also be problems with the turbocharger, which forces more air into the engine to burn more fuel. You may have a broken turbine, clogged passageway, or poor air filtration.

Strange Sounds and Odors

Listen to the engine when starting or accelerating. A grinding, banging, or whining noise often means a part is loose or pressure is building inside the engine due to a clog. Leaks or a lack of coolant can lead to burning smells and smoke under the hood. If oil or fuel spills into the crankcase, it will burn off.

Trouble Starting

If you have to turn the key multiple times to start the engine, air and fuel may have trouble reaching the engine for the same reasons mentioned above. You may also have faulty spark plugs, which provide an electric spark that ignites the air and fuel.

Your Subaru deserves the best. Our mechanics inspect every engine component to ensure optimal fuel efficiency, fast acceleration, and hassle-free starts. We will inspect your fluid levels, replace rusted parts, and test the engine before placing it back in your car.
