Thanks everyone - The coolant issue seems to have stabilised so I can work quietly on that in the background but no further sign of overheating. Some photos attached (if I can work out how.) Tony - there does appear to be a ledge about 1cm wide below the generator. The fan is generator mounted and appears to be new. I cant find any stamps below the (2?) water pumps but there is an upside down 87 ? on the RHS just in front of where the rh head is. All advice appreciated. Also thank you very much for the warm welcome.
