Car Trouble

In most situations, your car alerts you when something goes wrong. You have lights on your dash for nearly everything nowadays; alerts for oil changes to the dreaded “check engine” light. However, some warning signs that you car may need maintenance don’t come from your eyes – they come from your nose. Here are the smells to watch out for:

1. Burnt Rubber

This smell could mean slipping drive belts or misplaced, loose hoses that might be rubbing against rotating accessory drive pulleys. If the engine is hot, do not reach into it because this could be dangerous.

2. Hot Oil

This smell could mean that oil is leaking onto the exhaust system. To verify the leak, look for oil on the pavement or smoke coming from the engine area, but be sure the engine is completely off before checking inside.

3. Gasoline

This smell is likely the sign of a gas leak, or possibly a fuel-injector line or the fuel tank. This is a possible fire hazard, so take extra precaution before making any moves.

4. Syrup

This sweet smell might mean that the car is leaking engine coolant from a component related to the car’s cooling system. In any case, be sure not to open the radiator cap while it’s still hot.

5. Burning Carpet

This smell could mean brake trouble. Have your brakes checked as soon as possible, especially if you are noticing this smell during normal driving conditions, because this is a serious safety hazard.

6. Rotten Eggs

This may mean that the catalytic converter is not doing its job to convert hydrogen sulfide in the exhaust to sulfur dioxide properly. This could be the result of a poor-running engine, so bring it into get checked out sooner rather than later.

If you sense any of these smells, it’s a good idea to bring your car in to get serviced. Click here to make an appointment with Keffer Mazda’s service department today!
