Power Steering Pressure Hose

The initial step for replacing Power Steering Cooler pipe/hose with hydroboost requires removing the front grille and positioning a drain pan under the vehicle. Drain the reservoir fluid to avoid unnecessary contamination. Begin by disengaging the clamp which fastens the Power Steering Cooler inlet hose to the power steering gear as well as the clamp holding the Power Steering Cooler outlet hose to the Power Steering Pump. The Power Steering Cooler needs removal from the vehicle after you detach its retaining bolts from the radiator support. The installation requires positioning the Power Steering Cooler onto the radiator support followed by securing the bolts at 5 n.m (44 lb in). Fit the Power Steering Cooler outlet hose to Power Steering Pump by installing its retaining clamp. Secure both ends of the power steering inlet hose with retaining clamps at the power steering gear. Complete power steering system filling before bleeding the system. After that, inspect all hose connections for leakage followed by front grille reinstallation.

The procedure for fixing Power Steering Cooler pipe/hose in parallel hybrid trucks starts with disconnecting the energy storage box first. Add a drain tray on the ground under the truck chassis after removing the front grille. Siphoning the reservoir fluid will help prevent overflow during this process. First detach the clamps which secure Power Steering Cooler inlet hose to power steering gear while you detach the clamps which connect Power Steering Cooler outlet hose to Power Steering Pump.) to remove the Power Steering Cooler from the vehicle start by disconnecting the bolts which hold the unit to the radiator support. Position the Power Steering Cooler onto the radiator support then tighten its bolts to 5 nm (44 inch lbs.). Connect the Power Steering Cooler outlet hose to the Power Steering Pump before fastening it with retaining clamp. The power steering inlet hose requires connection to the power steering gear followed by attachment of its retaining clamp. Please perform power steering system filling and bleeding while inspecting all connector hose seals for leaks before putting the front grille back in place and reconnecting the energy storage box after maintenance.

The initial step when installing hydraulic boost requires users to confirm the vehicle stays off and seals every hose opening until replacement of the power steering hoses. The first step involves uninstalling both the hydraulic booster outlet hose from its respective locations on the Power Steering Pump and hydraulic booster. Both the hydraulic booster and Power Steering Pump must have their hydraulic booster inlet hose removed. Neptune asks technicians to detach the power steering inlet hose first from the hydraulic booster and power steering gear and then to remove the Power Steering Cooler inlet hose and Power Steering Cooler outlet hose from the Power Steering Pump. Connect the Power Steering Cooler outlet hose to the Power Steering Pump after following the fastener notice in service precautions then connect the Power Steering Cooler inlet hose to the power steering gear while tightening hose connections to 28 nm (20 ft. Lbs.). The power steering inlet hose should be connected to both the power steering gear and the hydraulic booster . Ensure to tighten the fittings to 28 nm (20 ft. Lbs.). The procedure requires you to connect the hydraulic booster inlet hose towards the Power Steering Pump while uniting it to the hydraulic booster before tightening both fittings to 28 nm (20 ft. Lbs.). To complete the procedure connect the hydraulic booster outlet hose and attach it to the Power Steering Pump as well as the hydraulic booster at 28 nm (20 ft. Lbs.) torque. Completion of secure hose connections requires bleeding the power steering system followed by hose leak inspections.

The first step to replace a power steering gear inlet hose without hydroboost entails lifting the vehicle before removing the engine protection shield. Position a drain pan under the vehicle before the power steering gear inlet hose requires removal from both the Power Steering Pump and power steering gear then disconnecting from the vehicle. When installing the power steering gear inlet hose put it in the identical position it held when you first removed it before securely fastening the fittings to 28 nm (20 ft. Lbs.) at the Power Steering Pump and power steering gear. You should drain the pan first before reinstalling the engine protection shield and lowering the vehicle while performing a bleeding procedure on the power steering system.

A drain pan should be placed underneath the vehicle before servicing the power steering line/hose with hydroboost. Seeking to service the power steering line/hose with hydroboost requires removal of the inlet hose first from the Brake Booster followed by the power steering gear before completely extracting the hose from the vehicle. The installation process should have the hose maintained in its original position before removal and the power steering gear inlet hose must be mounted towards the Brake Booster. Tighten all power steering gear inlet hose fittings to 28 nm (20 ft. Lbs.) while directing the hose to connect it to the power steering gear. The drain pan should be removed from beneath the vehicle before moving forward with the power steering system bleeding process.

The first step for replacing the Power Steering Cooler pipe/hose involves removing the front grille. A drain pan should be placed beneath the car while you use a siphon to remove power steering fluid from the reservoir to control any overflow. First obtain two clamp retainers to disconnect the Power Steering Cooler inlet hose from power steering gear and the Power Steering Cooler outlet hose from Power Steering Pump. Use a wrench to remove the bolts sustaining the Power Steering Cooler to the radiator support before pulling out the Power Steering Cooler from the vehicle. You should mount the Power Steering Cooler on the radiator support before securing its bolts at 5 nm (44 inch lbs.). The Power Steering Cooler outlet hose must be connected to the Power Steering Pump where a retaining clamp will secure it in place. The power steering inlet hose should be connected to the power steering gear with its retaining clamp installed. The power steering system should undergo filling and bleeding before examining hose connections for leaks while returning the front grille to its place.

Route the new hose in the same position as the old one.

Detach the clamp holding the power steering outlet hose from the power steering gear.

Remove the brake booster outlet hose from the vehicle.

Remove the power steering gear inlet hose from the brake booster and then from the power steering gear, followed by removing it from the vehicle.

Connect the power steering inlet hose to the power steering gear and then to the power steering pump.

Remove the clamp retaining the power steering outlet hose from the power steering gear and the clamp retaining the power steering inlet hose from the power steering pump.

Remove the clamp retaining the power steering cooler inlet hose to the power steering gear and the clamp retaining the power steering cooler outlet hose to the power steering pump.

Install a drain pan under the vehicle.

Detach the power steering outlet hose from the power steering gear.

Remove the power steering gear outlet hose from the steering gear.

Remove the drain pan from under the vehicle and bleed the power steering system.

Connect the booster outlet hose to the booster, install the retaining clamp, remove the drain pan, bleed the power steering system, and reconnect the energy storage box after servicing.

Connect the outlet hose to the power steering gear.

Position the clamp at the end of the hose.

Attach the power steering outlet hose to the power steering gear and install its retaining clamp.
