Hi Ron and list,
I've been thinking some more about A-series cooling systems and the expansion
tank on the Crossflow 1275cc cars.
I had thought about whether or not it would be worthwhile replacing the
copper/brass/?? tank with a plastic one. However, I noted that the Spridget
tank
has the overflow feeding into the top of the tank while the plastic tanks feed
into the bottom.
It seems to me that feeding the expansion into the bottom of the tank is a
better idea because that way the system can draw back coolant. On the other
hand the Spridget expansion tank has to be nearly full before it can draw
anything back unless the suction is really strong?
Is the height of the expansion tank an issue? Does the expansion tank inlet
have to be above the height of the radiator?
Regards
