I have a 98 t800 with detroit 60 and the low coolant light is on i changed the sensor on the reservoir tank but the light is still on can anyone help please
Fixed one before by unplugging the sensor and wedging a paperclip into the plug.... it worked so i electrical taped it up and left it alone. 98 379 with a S60
Dunno what your skill level or ability to access resources. You need to find out where the two wires coming from the sensor go to and ohm the wires.
