Ter info
Yet again doing some investigation into the TD5 code and I have to say.... Landrover / Lucas.... What the HELL were you thinking?
Attached is a plot of the temperature gauge output from the ecu to the gauge in a TD5 Defender.
The Plateau in green is actually the temperature range between 75°C and 115°C!
This in laymans terms means that the temperature gauge DOES NOT MOVE between 75°C and 115°C, then shoots up after that maxing out at 127°C.
By the time the temperature hits 115°C the potential for damage by overheating is extremely severe and considering the TD5 is an alloy head on a cast iron block,damage is likely to occur BELOW this temperature.
I implore all TD5 Defender owners to keep an eye on your coolant levels as this gem of information proves beyond a shadow of a doubt that the temperature gauge cannot be relied upon.
As a footnote the Discovery Gauge does not move between 50°C and 70°C and then run quite linear to 133°C, so does not suffer with this monumental cock up in programming.
