  Q: What are the ways to check the operation of the water pump while it's installed on the engine for Ford Crown Victoria?

  A: Water pump failure can cause overheating and serious damage to the engine. There are three ways to check the operation of the water pump while it's installed on the engine. If any one of the following three quick checks indicates water pump problems, it should be replaced immediately. Start the engine and warm it up to normal operating temperature. Squeeze the upper radiator hose. If the water pump is working properly, you should feel a pressure surge as the hose is released. A seal protects the water pump impeller shaft bearing from contamination by engine coolant. If this seal fails, a weep hole in the water pump snout will leak coolant. If there's coolant leaking from the weep hole the water pump should be replaced. An inspection mirror can be used to look at the underside of the pump if the hole isn't on top. If the weep hole is leaking, shaft bearing failure will follow. Replace the water pump immediately. Besides contamination by coolant after a seal failure, the water pump impeller shaft bearing can also prematurely wear out. If a noise is coming from the water pump during engine operation, the shaft bearing has failed - replace the water pump immediately. Note: Do not confuse drive belt noise with bearing noise. Loose or glazed drive belts may emit a high-pitched squealing noise. To identify excessive bearing wear before the bearing actually fails, grasp the water pump pulley and try to force it up-and-down or from side-to-side. If the pulley can be moved either horizontally or vertically, the bearing is nearing the end of its service life. Replace the water pump.

  Q: How to remove and install a water pump on Ford Crown Victoria?

  A: Removal begins with disconnecting the cable from the negative battery terminal. With the engine cold, drain the cooling system. Remove the fan shroud and the fan assembly. Remove the drive belt(s) and remove the water pump pulley. On 5.0L engines, if the power steering pump bracket is retained at the water pump, the power steering pump should be completely removed and laid to one side to facilitate removal of the bracket. On 5.0L engines equipped with air conditioning, remove the idler pulley and bracket assembly. Remove any accessory brackets that attach to the water pump. On 5.0L engines, remove the lower radiator hose, the heater hose, and the bypass hose from the water pump. Remove the water pump retaining bolts and remove the water pump. On 5.0L engines, take note of the installed positions of the various length bolts. Before installation, remove and clean all gasket or sealant material from the water pump, cylinder front cover, or cylinder block. On 4.6L engines, inspect the O-ring and sealing surface of water pump housing in the block for dirt or debris. Clean thoroughly before reassembly. On 5.0L engines, position new gaskets on the water pump and coat them on both sides with RTV sealant. On 4.6L engines, lubricate a new O-ring seal with clean antifreeze and install it to the water pump. Install the water pump and tighten the bolts. On 5.0L engines, it may be necessary to transfer some hose ports or fittings from the old pump if you are replacing it with a new one. On 5.0L engines, install the lower radiator hose, heater hose, and bypass hose to the water pump. Replace the hose clamps with new, if necessary. Install the remaining components to the water pump and engine in the reverse order of removal. Fill the cooling system with the proper coolant mixture. Start the engine and make sure there are no leaks. Check the level frequently during the first few weeks of operation to ensure there are no leaks and that the level in the system is stable.
