Who can tell me the temperature range that the cooling water reaches in the 2.2 TiD ? I mean the normal range / the normal temperature when the engine has run well warm. Is there a way to measure the value or to read the measured value from the engine control unit ? The display in the dashboard has no scale and is therefore somewhat inaccurate; a value +-3 degrees on a digital scale would interest me. ar realize an indicator in the SID ? Besides, I want to measure the temperature of the cylinder head . The easiest would probably be the installation of a sensor for a digital termometer . But where ? Just stick somewhere will certainly not bring a permanently reliable result . I would even go so far as to have a small bore applied and paste the probe there . But now it is quite unhealthy to drill any hole in the cylinder head without plan . Does anyone propose this Is it good?
