No that is not a good one for the D24, as it is pictured. Look at the side profile photo. Notice the lack of the bypass closing disk. That would allow a significant amount of coolant to continue to cycle thru the engine after reaching operating temperature, without being sent thru the radiator.

This one looks more like the correct one (notice the bypass disk on the engine block side), although it might not be a name brand Wahler like the one you linked, and does not have a small air bleed hole (which is much less important than a bypass blocking disk .)
