As I am intending to fit my engine tomorrow. I have just been sitting her thinking about the rad plumbing
Can you guys have a quick look at this diagram and see if it looks right.
Also does the 3 breathers by the question mark just T together or have I missed something?
Finaly, I seem to remember there was a pipe to the inlet manifold. Mind you that was a few months ago, so it could have just been a breather or
something.
Anyone put me right

does a cooling system HAVE to have a header tank? I'm sure they never used to... whats the benefits of having one? not wanting to hijack, just thought i'd ask
No idea
But who am I to argue
It either has one in the top of the rad, or a closed system like the one above doesn't it?

i was thinking both my BMWs had an expansion bottle built into the radiator itself, which is ok, but the likes of my old mini didn't have one at
all.
i'd like to keep mine simple, 2 hoses between radiator and engine and thats it sort of thing. i've not given a great deal of thought to it
yet, just thought when i saw this thread. i'm not using water heated heaters inside. just electric ones (whenever i get round to fitting a
windscreen. or i'll look for a heated windscreen)
anyways, sorry, this thread isn't about my car
David, i'm pretty sure you can just join those up with a T peice. i think the top of the header tank is supposed to feed back to the top of the
rad? or is it the bottom of the header feed the rad?

Yeah i know, but as your running an Ecotec i just wondered how you are doing it?
Off topic, new cars have expansion tanks because the radiator cap is lower than the water passages in the cylinder head. Your old MINI didn't need one because the rad cap was the highest point in the system, and when it got too hot the valve in the cap lifted and blew the coolant all over the road. These are greener times and we try to keep the fluids in their proper place.
ah, is that what it is! my radiator 'should' be higher than the engine, so i could get away with a simple radiator with pressure cap up front just plumbed into the engine?

The expansion tank is there as said to allow the water to expand when heated this will only be effective when there is enough air in the tank to compress, the old radiators were never filled to the top again allowing an air pocket for the water to compress, the rad cap is a pressure relief valve design to release excessive pressure in the system this could in theory be placed anywhere in the system but is in general at the highest point to assist filling and venting, the breather pipes are to allow trapped air to vent to the tank thus allowing the system to flow correctly hopefully without airlocks restricting the volume of water flowing. If the expanion tank is not large enough to allow the expansion of the coolant at max temperature then a expansion vessel as fitted to a central heating boiler could be plumbed into the system to add extra capacity.
Ever felt Hijacked ??
sorry
No prob's
I know this will seem like a bit of a hijack but its all along the same line ie plumbing.
I have fitted a coolman rad, due to space constraints, which obviously has a pressure cap. I have also fitted the expansion tank from the original
cooling system. at some point I need to do my plumbing.
Should I route the pipe from the rad neck to the expansion tank or should I just blank it off and return it to a sealed system or is there a non
release cap that would do the same thing.
