Water Pumps

A water pump is a mechanical device that circulates water through a system. In an automotive application, the water pump circulates coolant through the engine to keep it from overheating. Water pumps are typically belt-driven, and they can be either centrifugal or positive displacement. Centrifugal pumps use centrifugal force to move the coolant, while positive displacement pumps use a plunger or piston to move the coolant.

Types of Water Pumps

There are two main types of water pumps: centrifugal pumps and positive displacement pumps.

  • Centrifugal pumps use centrifugal force to move the coolant. The impeller of the pump spins, creating a vortex that draws the coolant into the pump and then forces it out the outlet. Centrifugal pumps are typically used in smaller engines.
  • Positive displacement pumps use a plunger or piston to move the coolant. The plunger or piston moves back and forth, creating a chamber that alternately fills with and then expels coolant. Positive displacement pumps are typically used in larger engines.

Water Pump Tools

The following tools are commonly used to service water pumps:

  • Wrench
  • Socket set
  • Ratchet
  • Screwdriver
  • Penetrating oil
  • Hose clamp pliers
  • Coolant
  • Thermostat

Water Pump Replacement

Replacing a water pump is a fairly straightforward task, but it is important to follow the manufacturer's instructions carefully. The following steps provide a general overview of the process:

  1. Drain the coolant from the radiator and engine block.
  2. Remove the drive belt.
  3. Remove the water pump pulley.
  4. Remove the water pump bolts.
  5. Remove the water pump.
  6. Install the new water pump.
  7. Install the water pump bolts.
  8. Install the water pump pulley.
  9. Install the drive belt.
  10. Refill the coolant.
