I used the dye in my coolant to find a leak I can see it under the intake on the drivers side and little in the front of the block by the head on the drivers side. I see there is a tube that runs under the intake but it does not appear to be leaking. Are 2000 3.8 V6 prone to coolant leaks under the intake. This is a very small leak there is no water in the oil and it runs great just wondering if any may have a direction to point me in before I start taking stuff apart

 

Most likely your lower intake gasket is leaking.
