For 2010 and earlier models, use the cap of the expansion tank as a hot radiator cap. To start the job, remove the cable from the negative terminal of the battery and flush the cooling system. For models made from 2004 to 2009, there is an engine cooling fan and shroud; you must eliminate these; in the 2010 model, there is an air intake duct, and you must do away with it. Remove the drivebelt and then replace the water pump pulley, when removing the pulley bolts unscrew them when the drivebelt is still intact to ease its removal. For V6 models, then detach the additional support bracket of the air conditioning compressor, then separate the heater hose fitting, and the lower hose of the radiator. Take out all the bolts that hold the water pump in place and take out the pump, use a soft-faced hammer to remove the pump if you find it difficult to pull it out. Across the bolt threads and the threaded holes in the engine, clear out degeneration and sealant, along with the rancid gasket residue and the sealing sections. Lubricate the shaft before installing it but for VS models wipe the O-ring surfaces on the pump and housing clean and if you are to use your old pump, it is advisable to use a new O-ring. This should be done to find out if the two pumps are the same or not and for the V6 models a thin layer of ATV sealant can be used to help in holding the new gasket in place. Make sure that the gasket is properly placed on the water pump and also make sure that the surface of the engine block is clean and free from old gasket before carefully assembling the pump with that of the water pump housing. The water pump bolts should be fitted and torqued to the recommended value as earlier stated then the process is reversed if the water pump is to be re-fitted. Finally tighten the water pump pulley mounting bolts up to the recommended torque, add the coolant in the cooling system and join the battery. In the end, crank it up and do a thorough inspection to look for signs of leakage. On the vehicle produced after December 2010, on 2011 and later models, following steps can be followed such as in fig 11 remove the air cleaner pipe, undone the nut on the water pump pulley, remove the drivebelt and water pump pulley. For 5.0L V8 models, uninstall the thermostat housing; and for 4.6L and 4.0L models, unplug the heater outlet hose from the water pump. Undo the water pump mounting bolts, scraped the O-ring surfaces of the pump and housing and if they are to be re-used, fit a new O-ring. Scrub up the interior of the bolt and the threaded holes of the engine, then inspect the new pump and look for difference between the new and the old pump. Connect the pump to the water pump housing gently, put the water pump bolts and turn them to the predetermined torque ensuring that one does not over-tighten the pump as this may cause some damage. If the water pump pulley was removed, undo the process to reinstall and then install the new bolts and tighten them to the required torque again fill the cooling system and reconnect the battery. Last of all, turn on the engine, and make sure the engine is leaking at any area since it produces high heat.

Water pump failure can cause severe engine damage. Three checks can identify issues while the pump is still on the engine. If coolant leaks from the pump's weep hole, the seal has failed. Noise from the pump during engine use suggests a failed shaft bearing. Excessive bearing wear can be detected by moving the pump pulley; if it moves, the bearing is worn and the pump needs replacing.

Inspect the O-ring and sealing surface of the water pump housing in the block for dirt or debris, and clean them thoroughly before reassembly.

Take note of their installed positions.

Using a flashlight, one can look for traces of coolant residue or dried coolant tracks around the weep hole(s). If the seal has leaked, it should be very apparent.

Yes, the water pump assembly does include the gasket as well

No, you can reuse the same bolts as long as they are in good shape
