Do not underestimate the ability of your nose when it comes to vehicle warning signs detection. With a sniff test there are unusual smells you can detect in your vehicle while the vehicle is on motion. They include the following:
- Hot Oil: The smell of hot oil could mean that oil is leaking onto the exhaust system. To verify this, look out for oil drop on the floor or smoke coming from the engine area.
- Rotten Eggs: This implies a problem with your catalytic converter not converting the hydrogen sulfide in the exhaust to sulfur dioxide properly. It can also be attributed to a poor running engine, causing the catalytic converter to become overloaded and fail due to meltdown.
- Gasoline: The smell of gasoline indicated that there is a gas leakage most times from the fuel tank, when the fuel cap is not tightly closed or from the injector line. Any smell of fuel can result in a possible fire hazard, so immediate attention should be given to the vehicle.
- Rubber: The smell of burnt rubber could be as a result of slipping drive belts, misplaced loose hoses that might be rubbing against rotating accessory drive pulley.
- Carpet: This could be a sign of brake issues most especially from the brake pads.
- Syrup: The smell of syrup may be a sign that your car is leaking engine coolant from a leaky component related to the car’s cooling system. It could be from the reservoir, hose etc.
It’s advisable not to ignore any odour perceived. Instead take your vehicle to a professional service center that you trust to get an informed opinion.
