So I replaced the water pump in my 2001 mustang gt the other day in which the part I got was requested for a 2001 mustang GT. In getting it back home the part set an additional 1" out past the rest of the pulleys regarding it being the wrong part. So I returned to the store and looked up a 2001 mustang GT Bullitt and what do ya know it was the right part. Now cosmetically my car has nothing telling me it is a Bullitt GT so my question is why does it have the Bullitt package engine in it and does that make it rare or is this common? It's 100% original only one owner before me and has 97k miles.

They changed the pulley mid model because of belt slippage.

There were several small mid-year changes to the 2V Mustangs in 2001 model year - one of them being water pump. Not sure the change had anything to do with bept slippage, but there were two versions, short and long snout and each used a different pulley as to stay lined up with everything else on the engine. Most of those affected the GT model, but I could see the Bullitt being affected as far as the change in water pump goes. My car has a mix of "early" and "late" parts, what they used just kinda depends on what was there as the car was being assembled. Besides the intake manifold, the Bullitt engine is the same as any other GT and the longblock would have been assembled right alongside all the other 2V engines.

Dammit I hate when I type out a thoughtful reply to a 9 month old thread where the OP has assumably moved on.
