A couple of weeks ago my low coolant light started to come on the first few minutes of driving then it shuts off. I tried stop leak thinking radiator and added coolant which lasted about 1 week and now it is happening again. the light comes on but the engine doesnt get any warmer. the light goes off after a few minutes and if the car is warm it doesnt comeback on again

Hi there,

You may just have a faulty sensor. But get the cooling system pressure tested first as if there is a small leak somewhere you will want to repair that first.
