mmgemini Posted March 1, 2006 Share Posted March 1, 2006 I'd like some help please. I'm after fitting a coolant loss sensor to my 300Tdi aluminium header tank. The fitting part is easy. I have a Range Rover pre 1989 coolant loss sensor part No PRC5077. This sensor works using a reed switch. When the reed switch is on and the level correct ,it will light an LED up but not a test lamp made from an instrument panel lamp.The light will go out when the level drops. The reed switch is not powerful enough to trip a relay. We can't find the Land Rover bit that the sensor uses to light the warning ligh.If anybody has that part number things could be easy. I'm stiil trying there as well though. So how do I get this light to work the other way. I can cope with wiring diagrams and if told how I can put the parts together. Any sensible suggestions welcomed. Do you think I [or anybody else] would notice the light go off at failure time??Assuming I wired the LED up to be on all the time and off when the coolant level drops. I eat rat poison mike I can cause trouble in an empty house Quote Link to comment Share on other sites More sharing options...
