Where this pipe goes

[OOO]

Found this in the box with pipes and hoses.
Where does it go, it seems like it is alloy, A/C or it is not Cosworth thing at all?

[Elfranco]

Water pipe thar runs along side the block below exhaust manifold, goes to heater box and thermostat housing

[Davecos 4x4]

Goes above the exhaust manifold.

[Elfranco]

Goes above the exhaust manifold.

Correct

[OOO]

If it is that one, why is diferent to this one?
The one above is from ST, maybe it is diferent to BT?

[the youth]

those top 2 pics are of a 2 wd water pump to heater pipe, it goes as said across the top of the exhaust manifold
I use them on my race cars the wrong way round to bypass the heaters from the 4x4 thermo housing

As Steve says, it's not an Escos one but will fit Small Turbo as they don't have the charge cooler fitted
