    This weekend I thought the car was on fire.
    White smoke with a kind of sweet smell coming from the engine bay shortly after warm up amd leaving an event.
    Pulled over and found the smoke coming from approximately the the left bank.
    No leaks under the car either.

    Gauges and temps were all normal prior to and during this event.

    Shut it down but was close to home so limped her home with no further smoking and no errant gauges except oil temp. It seemed kind of low.

    She's sitting in garage now still with a kind of sweet smoky smell.

    I haven't put her in the air yet but found this post.

    Based on smell is this what you guys had? Would the coolant have run to the front of the engine and cause a burnoff like that?

    Water pump (btw) was replace ~10k miles ago with next major coming up winter this year.

    TIA.

    Sounds like it smells like coolant. That sweetness. Possibly the hose connecting to the manifold or the actual overflow tank but that's not left side more right and center. If it is the center coolant tank hose the top of the engine between the intake runners will be filled with water. If you never replaced it do so, I did mine out of prevention and it was defiantly well past due, it would have failed at some point most definitely.

    On the left there is the radiator hoses, thermostat or its hose can leak, water pump lines also... That's about all that comes to mind. Check hose clamps for looseness and wetness.

    Long shot check AC and hoses the cooling charge is also a bit sweet smelling and is on the left.

    Is the water level in the overflow tank low, did you do any maintenance recently related to cooling?

    Pressure test your cooling system. Get right to the culprit without guessing.
