Here is the remainder of the information for the Heavy Duty Service Group.
It doesn't explain the internal differences but at least now we have part
numbers.
<<There are actually three different radiators used in the 2000 Dakota, here
are the part numbers:
52025816AB (which is used without the "heavy duty cooling")
There are two different part numbers for the heavy duty service group.
52025818AA
&
52028917AA
The transmission you have determines which of these two radiators was put in
your vehicle.>>
