Cosworth 4x4 header tank plumbing ?
I'm planning on using a 4x4 Cosworth header tank on my Sierra fitted with a V8.
Where do the two pipes go on a Cossy as I'm not sure on how to plumb it all in at the moment?

I’ve done a bit of research into this Mark as mines is a 4x4 engine but previous owner installed a 2wd cooling setup that I’m changing back to 4x4.
Two outlets on the headertank, one is the return water cooling from the turbo and the other connects onto the steel pipe that is fixed onto the bottom of the radiator that eventually goes to the water pump.

Some municipalities require them, but they are needed in a closed system,(if you have a backflow/check valve device on your water supply), some municipalities have backflow/check valves built into the water meter. There is a ball valve that has a expansion relief built into them, just do some googling for different thermal expansion products I've seen a 3 year old house piped in cpvc that blew the water piping due to thermal expansion, not just leak but blew the piping to shit, the cpvc was stretched so thin you could see through it.
