Power Steering Pump

Starting the Power Steering Pump replacement requires users to remove the pulley first while positioning a drain pan beneath the car to catch fluid overflow. Users should also cap or plug power steering hoses during this procedure to avoid fluid leakage. Disconnect all three hoses running from the power Brake Booster inlet to the power Brake Booster in addition to connecting the power steering cooler hose from the Power Steering Pump and the Power Steering Pump remote reservoir hose from its source. The technician should first support the vehicle before removing the rear mounting bracket nut of the Power Steering Pump then letting the vehicle rest at its original position. Remove the Power Steering Pump mounting bolts after pulling the accessory bracket forward and loosening its bracket bolts and nuts. The Power Steering Pump removal should include both the Power Steering Pump along with its power Brake Booster inlet hose. The power Brake Booster inlet hose installation process begins by connecting the hose to the Power Steering Pump followed by reinstating both components into their vehicle locations. Attach the Power Steering Pump mounting bolts before tightening them to 50 nm (37 ft. Lbs.). Install the accessory mounting bracket in its proper position before securing its bolts to 50 nm (37 ft. Lbs.) and its nut to 41 nm (30 ft. Lbs.). Rise the vehicle for installation of the Power Steering Pump rear mounting bracket nut but tighten it only to 41 nm (30 ft. Lbs.). After implementation, lower the vehicle. First uncap the power steering hoses before connecting the Power Steering Pump remote reservoir hose then the power steering cooler hose to the pump and finally fitting the power Brake Booster inlet hose to its appropriate spot and tightening it to 27 nm (20 ft. Lbs.). Install the Power Steering Pump pulley followed by a drain pan removal to bleed the power steering system then inspect the Power Steering Pump for leaks while checking the hoses have enough distance from the frame and other components.

The Power Steering Pump replacement process needs to begin by taking off the Power Steering Pump pulley. The drain pan should be placed under the vehicle while seal caps or plugs keep power steering hoses from fluid leakage. You need to disconnect three hoses: the power Brake Booster inlet tube from the power Brake Booster as well as the power steering cooler hose from the Power Steering Pump along with the Power Steering Pump remote reservoir hose from the Power Steering Pump. Begin by suspending the vehicle before you remove the mounting bracket nut at the back of the Power Steering Pump. Lower the vehicle while you loosen both accessory bracket bolts and nut and gently pull the bracket toward the front direction. Take out the Power Steering Pump together with the power Brake Booster inlet hose by first removing all Power Steering Pump mounting bolts. The power Brake Booster inlet hose should be attached to the Power Steering Pump first before reinstalling the Power Steering Pump together with the inlet hose into the vehicle. You should install the Power Steering Pump mounting bolts using 50 nm torque before tightening them to 37 ft. Lbs. Install the accessory mounting bracket followed by bolting then nut tightening. Both bolts should reach 50 nm (37 ft. Lbs.) and the nut should achieve 41 nm (30 ft. Lbs.). Raising the vehicle once more enables you to install the Power Steering Pump rear mounting bracket nut while tightening it to 41 nm (30 ft. Lbs.) before lowering the vehicle. Attach the remote reservoir hose of the Power Steering Pump by unfastening its ends while connecting the Power Steering Pump to its cooler hose. Secure the power Brake Booster inlet hose to its corresponding connection point at 27 nm (20 ft. Lbs.). The drain pan needs to be removed from beneath the car before fitting the Power Steering Pump pulley while performing a power steering system bleeding procedure. Ending your inspection check for leaks in the Power Steering Pump while verifying all hoses maintain enough space from frame elements and adjacent components.

The Power Steering Pump replacement requires two essential tools which include the Power Steering Pump pulley remover (J 25034-C) and the Power Steering Pump pulley installer (J 25033-C). Start by taking away the upper Fan Shroud before proceeding to remove the fan followed by removal of the lower Fan Shroud. Using appropriate caution prevent damage to pulleys and pumps when utilizing the power steering pulley remover (J 25034-C) to separate the air conditioning compressor. You should use the Power Steering Pump pulley remover (J 25034-C) to detach the Power Steering Pump pulley through a process of holding the nut while rotating the pilot bolt clockwise. Set a drain pan under the Power Steering Pump before you detach its mounting bolts and nut because you must cap or plug the power steering hoses to avoid fluid leakage. Unplug the power steering hoses from their positions on the pump before removing the pump unit. Begin Power Steering Pump installation by first placing it into its correct position before connecting the hoses to its rear side after uncovering their ends. Position the mounting bolts on the Power Steering Pump and tighten them to 50 nm (37 ft. Lbs.) while the nut requires a torque of 41 nm (30 ft. Lbs.). Hammering should be avoided when securing the pulley onto the shaft. Use the Power Steering Pump pulley installer (J 25033-C) to install the pulley at the pump shaft ending while guaranteeing the pilot bolt rests in the bottom position of the shaft. The pilot bolt receives your hand while you rotate the nut in a clockwise direction to settle the pulley correctly. Reroute the air conditioning compressor and lower Fan Shroud and fan unit with the upper Fan Shroud. Pour fluid into the Power Steering Reservoir until reaching the cold/full mark followed by power steering bleeding and leak and clearance check of hoses.
