Antifreeze / water pump issue

(1999 Lincoln Navigator)
in York, SC on October 15, 2010
I recently bought this car used. They just put a new water pump in however after driving 3-400 miles the reserve tank is empty again. The water we put in looks rusty and the tank looks dirty. Is that due to the type of antifreeze that may have been put in? What type should be in the tank?

Sounds like you have a coolant leak, you need to see if you have a leak and where the leak is (don't ignore the radiator cap, if the gasket is not in good shape get a new one). I'd say, refill it and see if the coolant level drops again. I think the rust is due to using water in the cooling system instead of 50/50 coolant and clean water. Think about getting the system flushed to get rid of the rust.
