Power Steering Pump

The replacement process for 4.8l, 5.3l and 6.0l power steering pumps starts by removing the power steering pulley before raising the vehicle. You need to unfasten oil pan skid plate bolts together with the skid plate from its location before placing a drain pan below. Lower the vehicle to install the power steering pressure hose from the pump while performing the pump replacement under the vehicle. First detach clamps (3,5) which secure the power steering return hoses to the pump and then take away the hoses. Begin by taking out the lower intermediate shaft of the steering gear and afterward strip away both the bolt between the engine and rear bracket then unscrew the front pump bolts. Transfer the vehicle pump to an outdoors area to separate it from the pump bracket at its rear section. Mount the bracket to the pump rear section before tightening the rear bracket retaining nuts to 50 nm (37 ft. Lbs.). The installation of the Power Steering Pump requires the attachment of the rear bracket to the engine using a bolt that reaches 50 nm (37 ft. Lbs.) torque. Fasten the front pump bolts with a torque of 50 nm (37 ft. Lbs.). Fasten the Power Steering Pump return hoses (2,4) using the retaining clamps after reconnection. The power steering pressure hose installation to the pump requires the vehicle to be raised before tightening the fitting to 28 nm (20 ft. Lbs.). You must put back the oil pan skid plate and attach its bolts while tightening them to 20 nm (15 ft. Lbs.). After lowering the vehicle reinstall the intermediate shaft together with the power steering pulley while performing a fill and bleed operation on the system.

You must position a drain pan below the vehicle before beginning power steering pulley removal to change the Power Steering Pump on your 8.1l engine. Secondly detach the clamp and nut which fastens the filler neck to the Power Steering Pump while checking for equipment presence. Begin by removing front-facing bolts of the pump before moving on to power steering mounting bracket retainer bolts and finally removing bolts at the rear of the pump. Starting with the removal of the pump, disconnect first the power steering return hoses (2,4) and pressure hoses from the pump. Remove the rear bracket attaching to the Power Steering Pump as the next step. Begin installation by placing the rear bracket onto the Power Steering Pump before securing its rear bracket retaining nuts to 50 nm (37 ft. Lbs.). Reinstall the Power Steering Pump into the vehicle while connecting the pressure hose through its fitting point with a torque of 28 nm (20 ft. Lbs.). Reinstall the power steering return hose attachments (2,4) while applying retaining clamps to their fittings then bolt the components securely to the pump with 50 nm (37 ft. Lbs.) torque. First install Power Steering Pump mounting bracket bolts while tightening them to 50 nm (37 ft. Lbs.), then proceed with front bracket bolts needing the same torque value (50 Nm or 37 ft. Lbs.). The procedure ends with installing the filler neck onto the Power Steering Pump and using the nut and clamp to secure it before tightening the retaining nut to 25 nm (18 ft. Lbs.). Next, perform power steering system fill and bleeding.

Start by detaching the power steering pulley before raising the vehicle. You need to first extract the power steering pulley and then apply a drain pan under the vehicle. The power steering pressure hose needs disconnecting from the pump while parking under the vehicle prior to lowering it. Through clamp removal (3,5), detach the power steering return hoses from the pump and extract them. First remove the lower intermediate shaft from the steering gear and then detach the bolt retaining the rear bracket to the engine before finishing by unplugging the pump from the vehicle. The bracket must be removed from the rear side of the pump assembly. To install the bracket you must mount it behind the pump while tightening rear bracket retaining nuts to reach 50 n.m (37 lb ft). Mount the Power Steering Pump in position before fastening the bolts to the front of the pump while tightening them to 50 n.m (37 lb ft). Reestablish Power Steering Pump return hoses (2 and 4) by using their retaining clamps. Secure the power steering pressure hose to the pump by tightening its nut to 28 n.m (20 lb ft). The vehicle owner should reinstall the oil pan skid plate and fasten it with bolts while tightening them to 20 n.m (15 lb ft). After lowering the vehicle workers must reinstall the intermediate shaft alongside the power steering pulley before filling and bleeding the power steering system.

Before replacing the Power Steering Pump on a 4.3l engine users must put a drain pan below the pump and remove the power steering pulley. Start by disconnecting power steering return hoses (2,4) from the pump before removing the power steering rear mounting bracket nut from the engine stud and then Power Steering Pump mounting bolts. The replacement process starts with accessory bracket bolt removal and its accompanying nut before forward motion of the bracket to extract the Power Steering Pump from the vehicle. First detach the power steering pressure hose from the pump while also separating the nuts from the Power Steering Pump rear bracket. After mounting the Power Steering Pump rear bracket on the pump, fasten it with nuts which require tightening to 50 nm (37 ft. Lbs.). Attach the power steering pressure hose to the pump by fastening its fitting until torque reaches 28 nm (20 ft. Lbs.). The first step involves securing the Power Steering Pump mounting bolts at 50 nm (37 ft. Lbs.) then attaching the power steering rear mounting bracket nut to the engine stud until it becomes tight at 50 nm (37 ft. Lbs). Reinstall the power steering return hoses and retaining clamps (3,5) onto the pump before readjusting the accessory mounting bracket for installation of its bolts and tightening the bracket bolts to 50 nm (37 ft. Lbs.) and the nut to 41 nm (30 ft. Lbs.). The final steps include installing the power steering pulley followed by filling and making necessary bleeding processes on the power steering system.

As a first step to replace a power steering pump you should put a drain pan under it then detach the power steering pulley. The first step involves disconnecting hoses from the pump then taking off bolts from its front section before taking off the four rear nuts. Remove the pump from the vehicle after taking away all components. Position the new pump in its installation place then secure it through tightening its front bolts up to 50 Nm (37 ft. lbs.). Fasten the rear nuts with the same torque of 50 Nm (37 ft. lbs.). Fasten the pump hoses back in place after securing their nut to 28 Nm (20 ft. lbs.) before reinstalling the power steering pulley. The power steering system needs to receive a fill-up before a bleeding procedure to finalize the install process.
