XFlow engine / Expansion tank or not ?

[darrell]

Still working on my Westfield / XFlow engine. I have noticed looking on the internet that some people use a expansion tank ( usually mounted on the firewall ) Is it better to have one or not ? Where on the engine would be best to hose for one ?

Overflow hose runs from the radiator to the tank. Tank should be be vented and allow coolant to be syphoned back into the rad when the car cools. Most radiators have a small tube in their neck just below the cap.

Cheap plastic tanks are available at most auto parts stores.
