MGA COOLANT OVERFLOW
I purchased a new MGA 1600 in 1961. Over the years, I have encountered problems of coolant loss in hot weather. I purchased after market surge tanks, but they did not fit to well in the engine area. At the local wrecking yard I found a late model General Motors factory plastic surge tank. It is approximately 6" long x 4" wide x 4" high. I mounted it under the top of the right front fender near the voltage regulator on top of the firewall shelf. Very good fit. I used a wire tie to fasten the overflow tube to the brake line. I ran a continuous 3/8" copper tube from the supply tube, around the valve cover, following the heater supply copper tube to the overflow tube on the radiator. Clamp the overflow tube to the heater tube. Bend the new copper tube 45o, and slip fuel line on the radiator overflow tube and connect to your new copper overflow tube. (Cut radiator tube with a hack saw.) Use fuel line as it will not crimp. Plastic tubing will crimp and restrict water flow.
This works very well and saves coolant.
