Water Pump Repair

Removal and Replacement Instructions
(steps 1-10 of 40)

  1. MAKE SURE THE ENGINE IS COOL. Drain the radiator by placing a bucket or drain pain under the radiator beneath the radiator drain plug and loosening the plug. The plug allows coolant to drain through a "channel" in the plug by simply loosening plug. It's best to rotate the plug so that the channel is on the bottom so that coolant can flow straight down and not up-and-around the plug. Remove the radiator cap to allow air to flow into the radiator and drain the coolant much faster.

CAUTION: The radiator drain plug will come all the way out of the radiator if you turn it too far. This will cause the coolant to drain much faster but it will also create a stream of coolant that will shoot over you drain pan and splatter off of the sway bar and other suspention parts and create a mess (we speak from experience).

  1. Remove the (8mm) screw at the mouth of the air cleaner snorkel and disconnect snorkel from air cleaner housing and remove (see picture below). The snorkel attaches to the air intake assembly with snap-in tabs.
  2. Loosen Mass Air FLow meter (MAF) clamp and PCV hose clamp using either the flat-blade screwdirver or the 8mm socket.

  1. Unplug the MAF connector (see picture above).

CAUTION:The MAF connector is secured with a "tab" style lock on the connector which is prone to breaking (especially on older vehicles). Be careful when prying up on the tab to release the connector. In our example vehicle someone had broken the lock tab apparently in a previous repair (note wire ties securing the MAF connector in the picture above).

  1. Remove the four (8mm) bolts securing air intake assembly (see picture above) and remove the air intake assembly with the MAF still attached.
  2. Disconnect the Intake Air Temperature (IAT) sensor from the air intake hose (see picture below).
  3. Loosen the (2) hose clamps securing the air intake hose to the throttle body(see picture below), detach the air intake hose from the throttle body and remove it.

  1. Loosen the hose clamp that attaches the upper radiator hose to the radiator (see picture above) and disconnect the upper radiator hose from the radiator.
  2. Remove the (4) bolts (11mm) that secure the fan / clutch assembly to the water pump. You'll need to reach down between the fan shroud and the engine to get at these. It's a bit of a tight fit but just take your time (and wear mechanics gloves if you have them).
  3. Remove the (4) bolts (8mm) that hold on the fan shroud. There are (2) bolts on either side of the shroud and they face the engine. You can get the upper two from the top but you'll need to get under the front of the vehicle to reach the other lower two bolts.
