Why does coolant go through the BAC valve?

Does it serve a purpose by going through it or is it just routed in that direction to get back to the radiator or where-ever? I didn't trace the line back to see where the line ends up.

I thought someone talked about this before, there is some vibrating thingy that causes alot of heat and actually needs coolant. Course I could be completely wrong

I read that post also. I think he is right. That pulsed solenoid gets real hot without the coolant running through it.

I have to wonder if that's why my car doesn't run perfect after it's run hard. I know there's a kink in the line somewhere causing the thermovalve to not get enough water.

What exactly does the BAC valve do? I can't remember.
