Cooling system flow?

[richieadkins]

Fairly certain I know the answer to this but, I am trying to figure out how the cooling cycle routes, does the radiator fill from the top or bottom. I have figured out the flow route just need to know the direction. This is for a distance learning project.

Cheers Richie.

top to bottom
otherwise it would suck any air thats trapped in the upper part of the radiator and stop flowing.
so it sucks from the bottom where there is always coolant

It is also due to the thermo syphon principle. Hot water always rises and displaces the cold water back to the engine.

Thanks guys was as I thought but just wanted to check for certain before makin an idiot of meself.

Thanks alot Richie

Convection (the natural action of liquids and gases to rise as they are heated and sink as they cool) this operation is just speeded up by a water pump which forces the coolant to circulate more quickly.

Any one got a schematic for the T25 cooling flow path?

I've been informed that it's opposite

Any good?
From Bentley manual I think

In the words of the great 'Scotty' ye canni change the law of physics.......
Hot coolant going in at the top of the rad....cooler stuff flowing back to the engine from the bottom of the rad........Time space continueum captain
