RD350 LC coolant flow direction

[irk_miller]

Can anyone in-the-know tell me the direction of coolant flow in an LC?  I am currently pushing coolant into the bottom of the rad, and wonder if I should flip the flow to be pulling from the bottom of the rad and pushing coolant into the back of the head.  It's working now, but when i have tested the current system in an overheat situation, boiling off any coolant creates an air bubble and if too much coolant boils out, I fear the coolant will quit reaching the top of the rad and not make it to the inlet on top of the head.

well, the pump rotates in the opposite direction of the crank on a stock one, so it pulls from the bottom. my tz pump pulls from the bottom as well.

Thank you.  Exactly what I needed.
