On a hot summer day last week, the car overheated. All the coolant was overflowing from the expansion tank and light smoke coming from the engine, so it seems like the engine is not receiving any coolant. Did a flush over the weekend, replaced the coolant. Same thing is happening again. I thought it was the water pump, but there're no leaks from the pump and no noises either.
What in the world is going on?
Thanks, guys.
