coolant,brake, and battery

ok recently i was at the macdonalds drive through and it looked like allittle bit of smoke from the left side under the hood then my coolant light, battery light, and brake light all came on but my car still runs fine....they only come on at idle and they ussually take a few minutes to come on when i first start driving...i just put a new alternator on it a month ago....does anyone else know what it is?

nevermind...i found it....i guess it was my alternater cause i swapped them out and its fixed so far....i think my water pump is leaking on it...

Thanks for stating what was causing your problem. I'd suggest getting that water pump fixed tho lol.

Yea I have the same lights on and I changed my alternator in the summer. They come on very faint and only at idle.. very very weird. Oh well..car runs fine.(knock on wood)
