123 cooling system ??
 

I see the output from the head. It then y's into two lines going into firewall next to each other. I see one outlet from firewall that then appears to go to monovalve and then to the coolant punp and then back to therostat housing.
Does anyone know why it y's off?? and how the coolant flows? A diagram would be helpful.

Knowing which year car you are referring to will help also....

Any VO mods done to the car?

sorry 83 w123 300d.......

not yet.

On mine, the hose comes out of the head on the drivers side...near the oil filter...and turns back and goes in the firewall. I don't remember it splitting. But that's where I tapped the coolant for my VO system.

Is there something wrong with yours or are you just curious?

Oh, here, I found a sketch of the coolant circuit.
Sorry its so small, I can email you a bigger size if you need it.
