Our truck constantly needs water. About every 2-3 weeks we have to fill it up. It never overheats, but the Low Coolant light will come on - and sure enough, there is room for water. About 1.5 years ago we had a similar problem but the truck was overheating. When we had it repaired they said the thermostat was out. They replaced the thermostat and it seemed fine for a while. This problem with the Low Coolant and slow loss of water has persisted for some time now. What would be causing this to happen?

I am almost certain that you have a leak somewhere in the cooling system. The easiest way to find this is to turn the car on and let it run and check around the water pump and hte radiator, also check for cracked hoses or hoses with soft spots in them.
