Hi.
I bought a kia rio 2008 1.5 CRDI with a leaky radiator , I replaced the rad and thermostat , however the blue coolant light stayed on , I changed the coolant temperature sensor but the light still stays on even after leaving the car idling for 30min and the fan kicked in,
What could be the problem?
Thanks
