The fan was on max speed at 110 Roger, when I’m motoring it can go up to 120 and then drop slowly back to about 100-105 when the engine is not pulling hard. It’s really weird that the stat temp appears to be normal at around 85-90 according to the laser but the gauge is reading 110. Jon M has suggested blanking off a portion of the rad to see if that makes any difference but it seems to me that it’s some kind of electronic issue because the OBD and gauge reading are near enough identical and the OBD is getting its info from the ECU, or am I wrong assuming that? It’s giving me a headache🤔
