I am losing coolant somewhere. Every 3-4 days my Coolant Level Low light comes on and I need to put coolant in. The van has never overheated and the the thermostat works. There is no leak under the engine onto the ground or driveway. Where could it be going?

HI there, you first need to have a pressure test done of the cooling system have this done with a warm hot engine and the heater on, this will locate any minor external coolant leak, start here.
