The Bullet Proof Diesel Billet Water Pump is designed for maximum durability. It features an aluminum impeller in place of the OEM plastic impeller, top of the line bearing assembly, top-grade seal and an all-billet precision machined housing. This stronger impeller resists cracking along the hub helping to prevent impeller failures, overheating engines and expensive repairs.
The aluminum impeller is also stiffer and stronger and therefore less likely to flex under heavy loads, leading to less cavitation and less erosion within the front cover. The billet housing is strong and more precise than a typical water pump cast housing. The top of the line bearing and seal are designed to go the distance.

- 2003 Models: If you have a 2003 you are in the 2003-2004.25 production date.
- 2004 Models: If you have a 2004 model you must check your VIN code to determine your production date.
- 2005 Models: If you have a 2005 or newer, you have a 2004.25 and newer production date.
A sample VIN code is: 1FTRW21P24EB10150. In the middle of the VIN code, you see the digits "4EB". The 4 means that it was a 2004 model year. The "E" denotes which production plant built your truck. In this case, E is for Kentucky. Lastly, the "B" is the start of the sequence number (the last 6 digits of the VIN). Some early 2004 models have a "4EA" code. The "A" denotes the early build and most likely is a 2003-2004.25 production date. For example letter "B", "C", "D" or more all denote later model 2004 builds with 2004.25 and newer production dates. For additional assistance with your build date, you can also contact your local dealer with your VIN number, or if the water pump is already off the truck you can measure the impeller.
