Hissing Noises
Hissing noises coming from the engine can be a sign of a vacuum hose leak or hot fluid dripping onto scorching auto parts. Your car’s engine will also hiss if the catalytic converter is clogged. An overheating engine can also hiss, or you may hear the coolant boiling in the radiator. Bring your vehicle to our shop right away if you hear the engine hissing.
Squealing Noises
A loose accessory belt will squeal when you first fire up your engine. It may or may not continue to squeal after the engine has started. You may also hear squealing when you turn the steering wheel if the power steering pump is going bad. Aside from the engine, the brake system can also squeal if it is too hot or you need new brake pads installed.
Knocking Noises
The engine can knock if the rod bearings in the cylinder block are too loose. When loose, the bearings cause the rods to move unevenly up and down inside the cylinders. Consequently, the pistons will knock against the cylinder walls. Poor detonation can also make the engine knock. Worn spark plugs, a lean fuel mixture, or the wrong octane can affect detonation.
Rumbling Noises
If you’ve got a hole in the muffler, the engine will rumble, especially when you press down on the accelerator. The engine will also rumble loudly if the catalytic converter has been stolen. As with a hole in the muffler, the rumbling noise will get louder when you accelerate. Another thing that can make your engine rumble is faulty spark plugs.
Popping Noises
You may wonder what a leaking exhaust system sounds like if a hole in the muffler makes the engine rumble. A leaking exhaust system can make popping noises. Another thing that will make the engine pop is a dirty air filter. To ensure you never end up with a dirty and clogged air filter in your automobile, have the filter changed every 19,000 kilometres.
