Place a large drain pan under the radiator drain plug. Drain and properly contain the engine coolant.
This procedure requires removing the engine timing belt and the auto tensioner. To help assure proper alignment at assembly, it may be helpful to set the engine at TDC on No. 1 compression stroke. This should align all timing marks on the crankshaft sprocket and both camshaft sprockets.
Remove the accessory drive belts and crankshaft damper.
Remove the right engine mount. This requires safely supporting the engine with a floor jack and wood block so the mount can be removed.
Remove the timing belt covers.
Remove the timing belt and tensioner.

Remove the water pump mounting bolts.
Separate the water pump from the water inlet pipe and remove the pump.
Thoroughly clean all sealing surfaces. Inspect the pump for damage or cracks, signs of coolant leakage at the vent, and excessive looseness or rough turning bearings. Any problems require a new pump.
Install a new O-ring on the water inlet pipe. Wet the O-ring with water to make installation easier. DO NOT use oil or grease on the O-ring.
Install a new gasket on the water pump and fit the pump inlet opening over the water pipe. Press the assembly together to force the pipe into the water pump.
Install the water pump-to-engine bolts and tighten to 20 ft. lbs. (27 Nm).
Install the timing belt and timing belt tensioner. Set the timing belt tension.
Install the timing belt covers. Install the right engine mount. Remove the floor jack and engine block from underneath the engine.
Install the crankshaft damper.
Install the accessory drive belts and set to the proper tension.
Connect the negative battery cable.
Fill and bleed the engine cooling system.
Start the engine and verify proper operation, with no leaks

Remove the belt (remembering how it goes back on, drawing the belt routing usually works) I find it best to remove the two top shroud nuts 13mm. Also removing the air box will allow for access under the alternator. Two 10mm bolts hold in the water pump. Clean the sealing surface.. install new water pump and gasket. Re-install components. Top up lost coolant making sure air is blead out, otherwise you will run into overheating issues.. Good luck
i would say you answered your own question, if there is water leaking from the water pump i would say the water pump is leaking and it needs to be replced,either the bearing is bad and its leaking out the shaft,or the seal is bad and its leaking outta there either way you need a new water pump,check the belt for wear when you replace it,,
No. You don't have to remove the timing belt to change the water pump. Check out the autozone.com website and register. It doesn't cost anything and you will have access to a repair manual for the vehicle. The steps for replacing the water pump can be found there. ( I checked) Hope this helps and best wishes.
