Water Pump

Service of the water pump starts with coolant draining. Beginning the service requires belt bolt loosening then belt removal alongside bolt removal of the water pump pulley. The first step involves draining the coolant before the bolts can be removed which separates the belt from the water pump pulley. The water pump needs removal followed by cleaning the mounting surface. The water pump housing should not be rotated after its installation because it will damage the O-ring seal and result in leaks. The service requires users to fit a new O-ring seal treated with proper engine coolant. After finishing the installation process you should follow the steps of the removal procedure in reverse order.

Service and repair of the coolant pump starts with draining the cooling system fluid. The next procedure involves bolt release for coolant pump pulleys before removing the accessory drive belt. The first step after belt removal involves the extraction of pulley bolts. Subsequently you should pull out the coolant pump bolts and remove the pump device. Discard the O-ring seal. The housing of the coolant pump must never be subjected to rotation after engine installation because it can injure the O-ring seal thus resulting in coolant leaks. Replace the O-ring seal with a new one which requires clean engine coolant for lubrication. The cooling system completion procedure starts with step-by-step return of the earlier removal actions followed by filling and bleeding the cooling system.

The service and repair of the water pump requires the draining of coolant as the initial step. The next step requires you to unwind the bolts before taking out the belt. The next step includes taking off bolts and the water pump pulley before extracting the water pump from the system. Thoroughly clean the surface where the water pump will mount. Installation of the water pump housing within the engine requires absolute restraint in preventing any rotation because such movement damages the O-ring seal which leads to fluid leakage. You need to add a new O-ring seal which must get lubrication by proper engine coolant. The installation procedure ends with performing the steps in reverse order of removal.

The service process of the water pump starts with draining the cooling system. Start your service of the coolant pump by first removing the accessory drive belt and then unstowing the four bolts securing the pulley to the pump. Apply a torque of 25 Nm (18 lb-ft) when tightening the new pulley bolts after removing the four bolts which secure the coolant pump pulley. The four bolts need removal together with the coolant pump before discarding the existing O-ring seal. During new coolant pump installation use fresh O-ring seals that must first receive lubrication using clean engine coolant before you fasten the bolts to 25 Nm (18 lb-ft). Engine failure will result from spinning the coolant pump housing after installation because it damages the O-ring seal thus causing leaks. The service needs completion through cooling system filling and bleeding.
