The engine coolant pump is located forward of the engine, located within the timing chain cover. The process should be initiated by the draining of the cooling system. After that, get rid of the cooling fan and fan shroud, and then the engine accessory belts, if reusing the belts, the direction of belt rotation has to be noted. Following that, disconnect MAF sensor electrical connection together with the vibration dampener and then uninstall the air intake duct together with the MAF sensor. Remove the coolant hoses on the
Thermostat housing and the cooling pump housing and turn off the connection of the thermostat and cooling system temperature sensor. Move on for the removal of the thermostat then the coolant pump pulley bolts to relinquish the pulley from the pump. Pull off the coolant pump fastenings; it is to be noted that there are bolts of different lengths used to attach this pump to the block. After loosening the bolts gently push/pull the coolant pump backward from the coolant pipes while being careful not to disturb the pipes from the connection to fittings at the back of the engine. For installation, simply reverse the removal procedures; remember to replace all sealing O-rings, and washers with new ones, when installing the pump, be reminded to treat the O-rings with the water based lubricant only during the adjustment, ensure the pump alignment dowels lies well on the timing case, and remember to fill the system with coolant and bleed it.
