Hey I have a 95 jeep grand cherokee that has engine coolant leak between the water pump and oil pan. When I get down to observe it it looks like its leakingfrom the oil pan gasket. I also checked to see if there was any coolant in the oil. There is none. Another note is it drips only when I turn it on and after a drive. The previous owner said they replaced pump. What am I missing here?
