The temp sensor looks right for a Thor. ( I had a RR Classic "Softdash" actually.) Not as cheap as I thought so maybe hold off changing it. But having a fresh sensor in stock could be wise as they are out of production and getting scarce -...

ETC8496 BLUE sensor/ black/brown connector ECU
Range Rover 4.0 P38 | '95 - '99 | Gems engine
Range Rover 4.6 P38 | '95 - '99 |...
