My 1938 Wraith WXA68 had a coolant leak. Investigation showed that there was corrosion in the coolant jacket in the inlet manifold at the return to the cylinder head. This is now being welded up. This appears to be due to electrolysis since the manifold is aluminium and the head is iron. Does anyone have a similar experience and are there any suggestions for prevention or retardation of this corrosion. Perhaps since WXA68 is having her 80th birthday this year, this isn't too bad.

Hi John, Evans Waterless Coolant claim that their coolant reduces the risk of hydrolysis damage, whether or not that statement is true is a matter that I can't confirm or dispute as I have not used their product. Perhaps you're already aware of Evans Waterless Coolant but if not you can google it and have a read of their product claims and decide for yourself. It's expensive stuff but lasts indefinitely which probably saves money in the longer term.

It is a common problem with all the Derby cars, lack of corrosion inhibitor is the reason. Put plenty of Bluecol/Prestone in the water.
