If you have a 4EA or 4EB VIN code (read below) then you might want to measure your impeller size before ordering to ensure the proper size and fitment. Please call if you have any questions so that we can help you with getting the right Bullet Proof Diesel water pump.
If you have a 2003 you are in the 2003-2004.5 production date. If you have a 2005 or newer, you have a 2004.5 and newer production date. If you have a 2004 model you need to check your VIN code to determine your production date.
A sample VIN code is: 1FTRW21P2 4EB10150. 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 2003-2004.5 production date. A "B", "C", "D" or more all denote later model 2004 builds with 2004.5 and newer production dates.
