What do these actually do guys for your cooling system ?

See the hose that connects into top that goes to header whats the function of this

 

stops ur system foaming up the top pipe bleeds steam ect into ur header tank . think thats right lol

cheers jay

 

Mmm intresting

 

it's designed to remove the air from the water system, the air rises to the top of the swirl pot and returns to the header tank through that pipe, that's my understanding anyway

 

your right in a sense i think bud, i believe that air pockets build up in the system causing hot spots where there is no coolant just air so the air pockets are removed in the swirl pot therefore getting rid of the hotspots

 

If you remove the cap of the header tank, you can see all the water going straight back into the head tank from the swirl pot

 

They take £100 out your bank acount!!!

Pete..

 

I cant , there does not seem to be any water doing anything from that pipe ?

Basicaly started engine and done so about 1 hr ago and only water i seem to have returning is turbo ? it was just started though does that make a diffeence , alloy header tank so can only feel for water , but defo does not seem to be any from the swirl pot pipe

 

rev it a bit mate and put some pressure in the system

 

And if there is no water coming up this pipe what does that mean

So let me get this straight , i should have water coming up this pipe from swirl pot to header tank

 

There will not be as much water coming through this pipe as turbo return.But there will be some.Have you just filled water as the thermostat may have not open yet and therefore no water is there yet.

 

Ehh basically started it from cold and it was trunning 2 or 3 mins , then opened header tank and put my finger in there was water from turbo return but didn`t seem like anything from swirl

A slight heat in water from turbo return

 

Mine is alloy too mate, can still see it, very clearly

 

Thermostat aint opened yet then so probably no pressure to push water up pipe.Leave it tick over until hose on rad side of swirl pot is hot then look.

 

In the dark

Cheers stretch My aRSe was collapsing to say the least there , because i do seem to have a bit of pressure in the tank when been out driving Was thinking of removing water feed to turbo to help but who knows

 

Keep an eye on temperature to make sure you aint got a airlock and turn heaters on full on hot inside car.Make sure it on flat surface as well.Is it a 4x4 or 2wd as on 4x4 there is a bleed screw on thermostat housing.

 

Is a 2wd stretch , my car always has a fair amount of pressure in it , but always thought it ways to do mostly with turbo return , as my mates have no return and not as much pressure , if that makes sense

 

it should only be air in that pipe coming from the swirl....

 

??

 

you will get a mixture of both air and coolant mate its just not a straight return as from turbo just a release like an engine breather type effect, no straight current but if enough pressure applied it will come out

 

i have never seen water coming out of that pipe mate...

steady flow out of the return to the turbo but should only be air from the swirl pot...

the purpose of the swirl pot is to remove any air bubble from your coolant.
