Causes of Car Smoke Under Hood
There could be a number of reasons why your Acura is smoking but not overheating. The most common reasons are because of:
- Oil spill or leaking component
- Oil filler cap
- Hot electrical wires
Below, we’ll thoroughly cover each of these reasons. Read on to find out more.
Oil Spill or Leaking Component
The first cause of smoke appearing under the hood could be from an oil spill. If you’re not careful when filling up the gas tank or adding oil to the crankcase, extra oil could appear outside of the engine. It would then produce a bit of a harsh, oily scent.
There could be other leaks, too, like from the coolant valve cover gasket. If this happens once or twice, it won’t do any major harm. However, if it keeps occurring and the issue is never addressed, it could cause long-term damage–like needing an engine or other part replacement.
Oil Filler Cap
If there’s burnt fuel inside the engine, the oil filler cap can release a little bit of smoke but not cause the car to overheat.
This could also happen if the piston rings are worn out or the PCV tube is clogged. These parts are used to drain off fuel into the cylinder, where it then burns and creates smoke. A crankcase ventilation is then supposed to pull smoke back into the engine to burn again. If the rings are worn or the PCV is faulty, this process can’t happen, and smoke will rise up from under the hood.
Hot Electrical Wires
You may start to see smoke and smell a pungent odor of ozone and hot metal if the alternator’s cooper wires are getting too hot.
This strong smell could occur if the alternator is completely burnt out. If that happens, though, the low voltage and check engine lights would most likely appear on the car’s dashboard.
What to Do If You See Smoke
If you notice smoke coming out of the vehicle, do not keep driving. Pull over to the side of the road as soon as you can and shut the engine off. If there’s also low oil pressure, see if you can add some fuel to the car and restart the engine.
Otherwise, you’ll want to get to a service center as soon as possible. You may have to get the car towed if you don’t feel comfortable driving it. There, a service technician can find the source of the problem and get it fixed for you in no time.
