Identification Guide for 4.6L Water Pump Pulleys
Visually identify which water pump pulley you have before installing regardless of the model year. The early water pump pulley
had a convex or ''bowed-out'' face and the pulley on the later water pump has a concave or ''pressed-in face''. There is no
exact changeover date for the pump and pulley. Supposedly the water pump changeover occurred in January of 2000, but we
have seen cars with identical January build dates and different water pumps and pulleys. We have also seen the early design
pulleys used on a few 2002 models. Refer to the pictures below to determine which pulley design you have. Since there is no definitive answer as to the timeline or model years.
