I have just replaced the rad in my sIII, which has a retrofitted 3.5V8 with a LPG conversion.
When I took the old rad out, I didn't really think that much about why pipes went from here to there, only where they went.
Now I'm putting them back, I'm starting to wonder why there is a pipe that goes from the radiator overflow (The small tube coming out just under the rad cap) into the part where the two SU carbs bolt onto.
There is an expansion tank to the right of the rad which is no longer connected to anything. I'm guessing that when it was a 6 pot the overflow went to the expansion tank.
I have been told by a work colleague that all Rover V8's have it, and it's for cooling the carb, but if this was the case wouldn't it need an in and an out to get the flow? Also it would only get the cooling if the rad overheated.
Any ideas anyone?
