My car doesn't have a Warning stencilled on the Radiator, but I've now got a High Top Rad to replace the later one that is currently fitted (car is SII).
As there's been discussion about when the Warning was first applied, I thought I'd take a look through Ray's Original Morris Minor book.
The only image of a Rad with the Warning is on p89, showing a 1098 engine with Elephant Trunk heater, so I'm guessing post '63....
There also a Radiator Pt Number change around that time according to the Parts List.
It changed from ARA 97 or ARA 101, to ARA 213 at car 1072761.
Now the change might have been the addition of the warning , but it's anyone's guess after all this time.
I just know I'm not going to put the warning on my new High Top radiator, despite ESM putting it on all theirs....
