The water pump is the heart of the Honda Accord's cooling system, circulating the coolant. If the water pump goes bad, it can seriously affect the vehicle's engine and cause damage. Make sure to change out a faulty water pump in your Honda Accord to keep the engine operating normally.
Disconnect the negative battery cables and drain the coolant from the cooling system.
Remove the drive belts from the engine, along with the water pump pulley. Remove anything that is connected to the front of the engine.
Break the crank pulley bolt loose with a 400 lb. electric impact wrench. Take out the pulley and the plastic covers as well as the valve cover. Replace the pulley after removing the valve cover.
Make sure that the timing mark on the cam pulley is pointing up and remove the timing belt.
Loosen and remove the three 10mm bolts to the water pump and remove the pump from the engine. Remove the old gasket from the block by scraping it off.
Install the new pump with a new gasket into the engine and tighten the bolts.
Replace the old timing belt with a new one.
Reinstall all components in the same order as you removed them, reconnect the negative battery cable and refill the coolant. Start the engine and check for leaks when it reaches normal operating temperature.
