Why does the check engine light come on when I start my Impreza?

Generally, your check engine light turning on upon ignition is not a bad thing. This is a sign that your vehicle is testing its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Are Subaru Impreza engine noises bad?

Strange engine sounds can be a sign something’s off in your Subaru Impreza. Tapping or knocking could mean you're low on oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Subaru Impreza engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving your engine while the vehicle is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Can I put water in my Subaru Impreza radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your Impreza when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What could cause my Impreza engine to suddenly stop?
