I decided to put a temperature gauge just before and after the radiator in the hope that it'll indicate if something is getting a bit warm. It may be a bit OTT, but they look good too. Anyhow, after getting them all fitted and wired up, I'm not so confident that they are working right or the wrong senders have been supplied. The temp gauge on the speedo never moves from the middle of the range and has been the same since when i got the car (4.0L V8), The Gauge before the radiator (Top Hose) shows about 115c and the lower Hose(Outlet) fluctuates between 80-100c depending on cruising down motorway or pottering about town. Does anyone know what the before and after the radiator temperatures would be on the v8 or is the normal water temperature higher than i thought?
The Senders are individually earthed and the gauges supplied with signal, positive and earth supplies. The pictures are of the home made 4 Gauge pod, could not find one to fit the Discovery Dash.
