But I'd certainly prefer to investigate any other possibilities.
92 was used by volvo for UK back in the 70's, 77 is too cold for any internal combustion engine in the UK ... lowering the thermostat temperature will not cure your underlying fault ..
Have you a volvo water pump on it or a motor factor one?
