My sister ran the car after it overheated. There is a bad coolant leak that appears to be coming from under the intake manifold. It is running along the block where it meets the head on the drivers side. There is also water coming from under the car on the passenger side, but am unable to see its origination. I know some of the engines have an issue with the intake manifoldleaking but could not find any info about the 3.0L. I will take the manifold off if I have to, but was hoping there was some info I need to know about this. I am hoping it is not a cracked head or head gasket.
