Hi Chris You have confused me now, with : > Are you sure you are looking at the right sender? Its not the one on the > Water pump, but under the air intake on the other end of the engine. When standing at the the back of the D looking into the engine bay directly in front of you near the water pump, is a sensor that screws, it looks like into the water pump housing. It has two very small spade terminals which connects to the lead. I assumed this was the temp gauge. Threre is also another temp sensor which is located on the water pipe, down low on the left hand side this controls the radiator fans. If the one that I think is the water temp gauge, not the water temp gauge do you know where it is. Could you also describe where the temp sender uner the air filter is. Thanks Kevin
