I,m assuming you mean the metal part of the bypass hose. Looking at water pump drivers side is a small metal tube hooked to heater hose. The tube is bolted through a alum bracket. Remove bolt and pull tube out. May need to spray with penetrating oil as these corrode, and are stubborn Make sure vehicle is not hot. No need to drain coolant as it will come out of bypass hole. have drain bucket ready. Do not reuse o- ring as it will leak.

Need to replace water pump on a 2000 Dodge Durango. Would like any details on how to to it.

3.9L, 4.7L, 5.2L, 5.9L, 8.0L Gasoline Engines
  1. Carry out the "Common Steps" above.
  2. Remove the upper radiator hose.
  3. Remove the fan and shroud assembly.
  4. On engines except 4.7L, remove the four water pump pulley bolts and remove the pulley.
  5. Remove the heater hose pipe mounting bolt, if fitted.
  6. On engines except 4.7L, loosen the bypass hose clamp at the water pump.
  7. Remove the seven water pump mounting bolts and, on the 4.7L, one nut.
WARNING Bolts may be of different lengths. Be sure to note their locations.
To install:
  1. Reverse the removal procedure.
  2. The 8.0L engine uses an O-ring to seal. Use a new one and lubricate it with petroleum jelly before installation of the pump. Also, use sealant on the threads of the heater hose pipe, position the pipe as shown before installing the pump and tighten the nut to 12 ft. lbs. (16 Nm).
  3. On pushrod engines, connect the bypass hose to the pump while installing it.
  4. Tighten the bolts to 30 ft. lbs. (40 Nm) on pushrod engines, 40 ft. lbs. (54 Nm) on the 4.7L engine.
  5. Spin pump to ensure the impeller is not rubbing against the timing chain case.
  6. When installing the heater hose pipe, ensure that the slot in the pipe bracket is bearing against the mounting bolt. This will hold the pipe in as far as possible to prevent leaks.
  7. Tighten pulley bolts to 20 ft. lbs. (27 Nm) on V-6 and V-8, 16 ft. lbs. (22 Nm) on the V-10.


Fig. Water pump bolts differ in length; note check location before installation-3.9L, 5.2L, and 5.9L gasoline engine shown

Hope helps (remember to rate this answer).

2001 Dodge Durango 4.7 automatic . put in new radiator new thermostat hoses and cap , water pump is good as well , still runs hot water keeps flowing out of where the cap goes . No water in oil and no oil...

sadly it sounds like you have a blown head gasket...Does the coolant  smell like exhaust?  I hope you don't but, everything points in that direction.  Try bleeding the coolant system.

the upper rad hose goes from the rad to the thermostate housing. this hose is @2-21/2" the lower hose same size goes from lower rad to water pump. There is a 5/8 hose from water pump to thermostate housing called bypass hose. and you have two hoses from water pump and intake to the heater core. hope this helps if not let me know thanks
