Had a great discussion with another EO member today (who shall remain nameless at this stage).

With all the drama about my cooling issues, the subject of coolant flow came up today......what direction does coolant flow through a normal radiator (ie: one with a top and bottom tank.....not a cross flow). I've had a life long belief that the coolant travels into the radiator via the top hose, gravitates to the bottom tank being cooled along the way and then gets sucked back up into the motor via the bottom hose by virtue of the water pump.

My good mate (still nameless at this stage) reckons it's the other way around.....the coolant goes from the radiator, out the top hose into the cylinder head, then to the block and down the bottom hose into the bottom tank and back up to the top tank.

What's the concensus amongst the experts?

Cheers
