  Q: How to Install a Water Pump on a 3.7L Engine on Dodge Nitro?

  A:

  For water pump installation on 3.7L engines, make sure you first clean the parts that touch the gasket. After putting in the new gasket, put the water pump in place and tighten all the bolts to a torque of 54 Nm (40 ft. lbs.). Be sure that the water pump spins easily and splash cover is not touching the timing chain case. Install the radiator lower hose to the water pump and add the accessory Drive Belt. It's important to secure the upper fan shroud to the assembly, connecting it to the bottom piece so that all the air in the cooling system passes inside the radiator. Place the two fan screws and make certain the tips of the fan blades are at last 25 mm (or 1.0 inches) from the fan shroud. Remove the air, add coolant to the system and connect the negative Battery Cable next. It's important to check for leaks in the cooling system as well.

  Q: How to Remove and Replace a Water Pump on a 3.7L Engine on Dodge Nitro?

  A:

  It's important to clean the surfaces of the water pump gasket before removing and replacing it in 3.7L engines. With a new gasket in place, affix the water pump and screw in the bolts up to 54 Nm (40 ft. lbs.) of torque. Without touching or rubbing the timing chain case/cover, the water pump should be allowed to rotate properly. Join the radiator lower hose to the water pump and then fit the accessory Drive Belt. Secure the fan blade/viscous drive assembly behind the upper fan shroud and make certain the shroud's upper and lower parts are joined together properly to let all air flow through the radiator. After installing the two fan shroud-to-radiator screws, check that the fan blades do not come closer than 25 mm (1.0 inches) away from the fan shroud. Add coolant to the old cooling system, put the negative Battery Cable back in and start the engine as you keep it running and monitor for leaks.
