• Q: How to replace the Power Steering Hose inlet and outlet on a 4.2L engine on 2008 GMC Envoy?

  A: A proper replacement of the power steering gear inlet and outlet hose on a 4.2l engine requires first lifting and securing the vehicle. Start by taking off the engine protection shield and beneath the vehicle position a drain pan. The Power Steering Hose assembly requires disconnecting from its retaining bolt on the power steering gear before detaching from the power steering gear itself. Start by disconnecting both the power steering return hose and Power Steering Cooler hose from the Power Steering Cooler. After that disconnect the power steering pressure hose along with the Power Steering Cooler hose from the Power Steering Pump. The technician must lower the vehicle position before removing the Power Steering Hose assembly from the front crossmember bracket mounting bolt. Open the battery compartment and remove the fuse block cover before taking apart the negative Battery Cable and positive Battery Cable on the fuse block. Start by unplugging the wiring harness connector from the fuse block until you remove it from its bracket. Afterwards, disconnect the fuse block wiring harnesses from their wiring loops while also taking off the wiring harness clips from the fender. Disengage the upper fuse block locking tabs from the lower fuse block before you detach the upper fuse block bolts and position it on the engine. The Power Steering Hose assembly bracket retaining bolt at the wheel well needs removal along with the bracket before proceeding to remove the Power Steering Hose assembly retaining bolts. The technician must disconnect the Power Steering Hose assembly and thoroughly clean both the power steering gear inlet and outlet ports. An operator should employ the j 44586 power steering gear oil seal remover/installer (J 44586) to remove the power steering gear oil seal from the power steering gear by using a flat-bladed tool for additional traction. The first step is to place the hose assembly on a workbench where you will identify hose positions before removing the 3 retaining clamps to extract the damaged Power Steering Hose. The repair process begins with hose assembly installation followed by clamping the assembly with three retaining clamps and using j 44586 (J 44586) with its seal installation end to insert a new power steering gear oil seal. Lower the vehicle before you fit the Power Steering Hose assembly back into its position and verify that the power steering gear oil seals fully engage their pockets. A technician should install the Power Steering Hose assembly bracket to frame brackets using retaining bolts at a torque of 10 n.m (89 lb in) and attach the Power Steering Hose assembly bracket to the wheel well by tightening its retaining bolt to 10 n.m (89 lb in). Place the fuse block connectors correctly in the lower block before mounting the upper block to the lower one by connecting its locking tabs. After tightening the fuse block hardware to 6 n.m (53 lb in), reconnect all wiring harness clips in the fender before attaching the fuse block wiring harnesses to wiring loops along with connecting the wiring harness connector to the fuse block. The positive Battery Cable must reconnect to the fuse block while the negative cable goes to the fuse block followed by installing the fuse block cover and the battery tray. Secure the Power Steering Hose assembly onto the front crossmember bracket mounting bolt with a torque of 10 n.m corresponding to 89 lb in. Dismount the vehicle before installing the Power Steering Cooler hose and power steering pressure hose to the Power Steering Pump while completing the bolt tightening at 25 n.m (18 lb ft). Use the retaining bolt to fasten the Power Steering Hose assembly at the power steering gear while tightening it to 12 n.m (106 lb in). Afterward, secure the power steering return hose and Power Steering Cooler hose to their position at the Power Steering Cooler. The last steps include removing the drain pan, installing the engine protection shield, lowering the vehicle before performing power steering system bleeds.
