Does anyone know the direction of coolant flow in an LS (as oppsed to SBC) set up? I know the flow is the reverse of an SBC but is that just engine circulation or radiator aswell?
ie. does the flow from the engine go in the bottom of the radiator or the top?
Flow from engine should always go in at top of rad. As far as I am aware coolant flows opposite way in LS so coolest gets to heads first. As far as which is "in" connection and which is "out" on a LS I don't know because I have not fitted one.
