The water pump bypass hose on some Dodge Ram 1500s is very challenging to replace because it is located in a difficult place to reach, especially where it connects to the water pump. The replacement process can be time consuming and frustrating, but with some patience, the right tools and a game plan, it can be done.
Unbolt the A/C compressor from the bracket and move it to the side. (It may not be necessary to completely disconnect the compressor.)
Unbolt the alternator from the bracket and move it to the side. (It may not be necessary to completely disconnect the alternator.)
Unbolt the bracket from the engine block and move it to the side.
Using the torsion spring hose tool, spring the two hose clamps, remove the bypass hose, and replace it with the new one. Replace the spring-type hose clamps with screw-type clamps.
Reattach the bracket, the alternator and the A/C compressor. Start the engine and check to see that all components are working properly.
