Water Flow Direction

[weejimmy 1]

what way does the water flow in the engines?

is it out the distrubution block at the back then in the botom of the rad and out the top back into the head?

or does it get pumped out the engine via the head and back in the water housing at the back?

 

cheers

Hot water rises, so I guess out the distribution block and up through the rad.

I'm pretty certain it's out the engine via the thermostat housing into the top of the rad then out the bottom (as the thermostat determines whether the water flows through the rad or not, and the coolant temp sensor is here and it should be measuring the temp due to engine heat ie water leaving the engine)

Tom Fenton posted a good diagram recently clicky

I'm unsure but tend to agree with sports post above after a friends car had a split top hose & it only leaked once the thermostat started to open.

 

CTS is within the closed thermostat loop though on the heater matrix side of things.

Here's a clue

Think about where the water pump is positioned and which way the engine turns

yeah but it could pump out out from the botom of it out the rear housing or out the top into the block

Get the ketchup ready.....

 

Starting when the engine is cold, thermostat is shut. The water pump at this time circulates water from the rear distribution housing, thru the block and head, across to the thermostat housing. The thermostat is shut so water gies thru the heater matrix, and by pass pipe on the mi16, back to the rear distribution housing. As only a small volume of water is circulating it soon gets hot, this causes the thermostat to open. When this happens, the water pump takes cool water from the rear distribution housing that has come either from the rad or th heater matrix. Pushes it across the block to take heat away from the block and head. Reaches the thermo housing where most of it goes thru the main rad to cool, while some of it goes thru the heater matrix.

now i've confused the f**k out of myself thinking about this changed what i've wrote 3 times you think working in the water industry i've have this sussed when i've tested thermostst's in the past i stand them in a pan of boiling water and the valve opens so am i right in thinking when the water behind it reaches temp it opens to allow it to flow through?

 

i'll get it in the oven tom and warm it up for my tea
