hi guys i know its been covered before but just checking im sorting the problem out. this is how i have it now

when the engine is running and i put on a few revs the water fills the header tank

its a x-flow 1.3

you can see the header is plumbed into the heater side of things

is this the right fix

Hi

I had a very similar problem which I believe i've solved by reconfiguring my plumbing to look like this.


Revised xflow plumbing

Obviously, as you can see i'm not running a heater but the solution was to T the header tank into a low pressure section of the coolant flow.

Cheers
Gary
