I understand there are 2 different pumps. I’m hoping these pics will help someone identify which pump to order from TA. Thanks in advance!
lt's the long one,that pulley is for the long water pump. The short water pump pulley is half the size of that one in length from the water pump to the radiator. Bruno.
The easiest way to tell for the 455 is to unbolt the fan clutch, and note the shaft extension above the flange. For the the long pump, it is 1", for the short pump, it is 1/2". See the picture.
