Not sure, Just doing some reading, and the D1 coolant pressure is 15psi, whereas the D2 seems to be 1.4Bar. (which is 20.03psi). This would indicate a different cap set pressure.
More research....sorry can't be more help

Yes, more reading and that is corrrect.
I would be sure to get the right part. knowing the engineers, it was the same size....lol. As they saved $ on the tank remanufacture, but the pressures are definitely different.
