Radiator Breather Tanks What Do They Really Do

[mattsr31]

as title says what do breather tanks do is it that they let air out of cooling system or what

i got a greedy 1 all in japanese can any tell me a best way to fit one up

in skylines, the radiator cap is lower than other parts of the cooling system, hey do this so the front of the car can be lower.. that is why you need to bleed the air out of the bleeder in the inlet manifold..

the breather tank moves the cap higher than everything else.. so if you mount it on the strut tower, with the second cap above the engine, it now becomes the highest point and all the air in the system will gather there, allowing you to easily bleed the air from the system by simply running the engine and filling it up..

rb's if not bled properly will gather air in the cylinder head as its higher than the radiator and the cyl head temps will get high and cause damage also the pressure of the cooling system will be low and it will do bugger all.. so its important to bleed them. breather tanks are better value for money than catch cans if you ask me.

so with the breather tank u dont need a bleed bolt no more as i remove it when putting greddy intake on my car and the realised thati cant bleed air for cooling system so with the breather tank i can bleed the air out

thats correct.

thank heaps mate

how do u hook a breather tank up the right way as its in japanense

im assuming that the bleeder has a radiator cap on top.. what has come in the kit??

most of them have a t piece that plumbs into a coolant line, or the coolant line gets replaced by the lines and bleeder tank.. just like a catch can arrangement but with coolant instead of blowby.

here is a couple pics of what it come with i think i need to buy the big split in the bottom rad hose

The picture looks like it explains it. Yes you need to get a tee for the bottom radiator hose. You can buy these for water temp sensors. You will then need to get a nipple that screws into it to attach a hose to. The top end looks like it sits between the over flow bottle and the radiator. the highest to the overflow bottle the lowest to the radiator. The other one can be capped off. Just make sure that you mount the top of it higher than the cap of the radiator so the air rises to the breather tank.

that is how i trought it would go just wanted to make sure

it has to sit higher then any coolant running around right so the dose that mean it has to be higher then the coolant line it the top of the turbo has i have a hi mount
