Loud noise, lots of smoke. Still drives just fine. Sign In

Hello all. I could really use some advice on what my be wrong with my mini van.

It's a 2010 Honda Odyssey. Yesterday while I was waiting on my wife to come out of a store I was siting in the car as it idled. All of he sudden it started to make a very loud sound with a lot of white smoke pouring out from under the hood. I immediately turned it off.

My wife could hear and see it all from inside the store. Right after I turned it off I looked under the hood. The smoke left very quickly. I am not mechanic but as far as I could tell, everything looked good. I had my wife start the car up again as I looked under the hood so I could see where the noise and smoke was coming from.

It ran just fine. No noise and no smoke. We drove it home with no problems.

This morning it was dead. I had to jump it. No lights were left on that we could tell. I suspected something was wrong with the alternator. A friend of mine came to look at it with me. The batter and alternator seem to work. The battery now registering about 12 amps without it being started. It was registering up to almost 14 amps when the care was running.

We let it idle for about 20 minutes and the noise returned with the smoking. We are unable to tell exactly where the smoke and noise came from. It looks to be near the alternator or AC. The AC was off when we heard the noise today.

There is only one belt on my Honda Odysseys that I can see. It is the timing belt and it seems to look and feel like it is in good condition.

Does anyone have any ideas? Could the alternator be half way working? Smoking and making noise some time but working at others?

Thanks in advanced for any advice.

Quit playing with this thing! You don't know where or what type of smoke or noise or what to name things so send it out. It might have been a small problem or not but driving it and letting it run like that now it's probably real trouble,

I agree. If you don't know the difference between volts and amps and timing belt and accessory drive belt, you need to have a reputable repair shop look at it.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
