Hi Alan,
Can't TR4s easily be made to draw radiator coolant back to the radiator from
the catch tank when engine cools off - rather than the bottle simply being
used as an overflow catcher?
I bought a NOS Stanpart TR4 spec'd radiator cap that has additional gasket to
seal the top of neck (rather than just metal-to-metal neck connection) as
well as the rubber seal for the inner filler hole plus a smaller built in
'return' valve.
I assumed I could have a good "closed" 'back-and-forth' system..
Wrong?
Regards,
Carl

tank.
That's all that were ever fitted to TR4s. You can mount it just about
anywhere
because the coolant won't be sucked back into the radiator. It's a one way
trip.
