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

  A: A faulty water pump can cause engine damage due to overheating. Three ways to check the pump are: squeezing the upper radiator hose while the engine is running, which should result in a pressure surge; checking the weep hole for coolant leaks, which indicate a seal failure; and listening for a howling sound or feeling for shaft wear in the pulley, both signs of bearing failure. If any of these issues are present, the water pump should be replaced. Don't confuse drivebelt slippage, which causes a squealing sound, with water pump failure.

  Q: How to replace a water pump in a Hyundai Excel?

  A: Disconnect the battery's negative terminal and drain the cooling system. Detach the radiator hose from the water pump and remove the left engine mount for 1994 and earlier models. Loosen the water pump pulley bolts, remove the drivebelts and pulley bolts. For 2011 and earlier models, remove the timing belt, tensioner, and alternator bracket. Detach the water pump from the engine, noting bolt locations. Clean bolt threads and engine holes. Compare the new pump to the old one, remove old gasket material, and clean mating surfaces. Install a new O-ring in the coolant pipe, lubricate with coolant, and apply RTV sealant to the new gasket and pump. Attach the pump and gasket to the engine, threading bolts finger tight. Install remaining bolts and tighten in 1/4-turn increments. Reinstall removed parts, refill the cooling system, and check drivebelt tension. Run the engine to check for leaks.
