  Q: What are the signs of water pump failure and how can it cause engine damage?

  A: A failure in the water pump can cause serious engine damage due to overheating. With the engine running and warmed to normal operating temperature, squeeze the upper radiator hose. If the water pump is working properly, a pressure surge should be felt as the hose is released. Water pumps are equipped with weep or vent holes. If a failure occurs in the pump seal, coolant will leak from this hole. In most cases it will be necessary to use a flashlight to find the hole on the water pump by looking through the space behind the pulley just below the water pump shaft. If the water pump shaft bearings fail there may be a howling sound at the front of the engine while it is running. Bearing wear can be felt if the water pump pulley is rocked up and down. Do not mistake drivebelt slippage, which causes a squealing sound, for water pump failure. Spray automotive drivebelt dressing on the belts to eliminate the belt as a possible cause of the noise.

  Q: How to replace a water pump in a Toyota Land Cruiser?

  A: Disconnect the negative battery cable and drain the cooling system. Ensure you have the stereo's anti-theft activation code. Remove the power steering belt, alternator/water pump belt, and air conditioning belt. For 1992 and earlier models, remove the power steering idler pulley, bracket, and alternator brace. Remove the fan shroud, fan assembly, and water pump pulley. Disconnect the radiator inlet hose and bypass hose. Remove the water pump and replace the gaskets. Clean all sealing surfaces and reassemble the water pump. Installation is the reverse of removal. Tighten the water pump bolts, refill the cooling system, and check for leaks.
