2005 3.3L V6 Town&Country minivan Extended length wheelbase.
99,000 miles.

Spotted a coolant leak today on my Mon's van:
driver's side lower radiator corner
near where the transmission cooler lines connect.

As best I can see the leak may be where
the bottom of plastic side tank
crimp connects to the aluminum radiator core.

No sign of coolant in the ATF and trans dipstick level was at mark.
Radiator was still full but overflow tank was empty.
No sign of dents or impacts.

Is there something else near that spot
that commonly causes a coolant leak on these vans?
