The last week and a half the “Coolant Light” has been on, I have check the coolant levels and they are fine, also check the reserve. Could the sensor be Fook uP ? or is there another sensor else where ? :-o
Yeah take out the resivoir tank and check the sensor, it´s a little black thing and should have a wiring harness coming off of it. Just look-see it over. Chances are it would be cheap to replace anyways.
