You didn`t mention what year it was but they have a history of the intake manifold leaking in the rear causing anti freeze leak ......also have heater control vavle problems leaking coolant. The best thing todo is have the sytem pressure tested to make sure where coolant is coming from ...intake gasket don`t cost too much but labor charges can be a bit because its not a simple job on some
