QuestionHow do u change high pressure and low pressure power steering lines on a 2000 Chrysler Concorde with a 3.2 engine
AnswerPOWER STEERING FLUID HOSES (PRESSURE AND RETURN)
NOTE: On this vehicle the power steering fluid pressure and return hoses are connected together by their mounting brackets. For this reason both hoses need to be removed together if either of the hoses should fail. Use the procedure below for the replacement of either power steering fluid hose.
REMOVE

300M only - Reinstall front fascia.
Lower the vehicle until the tires are just clear of the floor
Install the power steering hoses onto the left frame rail Power Steering Hose To Frame Rail Mounting by installing the routing clip bolts. Tighten the bolts to 10 N·m (89 in. lbs.)
Slide steering gear and intermediate shaft back into dash panel sealing boot. Align the steering gear mounting holes with its mounting holes in crossmember.
Loosely install the bolts mounting the left side of the steering gear to the crossmember Steering Gear Attachment To Crossmember (Left Side)
CAUTION: Tightening the steering gear to crossmember mounting bolts to the proper torque is very important.
Install the bolts mounting the right side mounting bracket for the steering gear to the crossmember Steering Gear Attachment To Crossmember (Right Side) Tighten the mounting bolts to a torque of 58 N·m (43 ft. lbs.)
Tighten the bolts mounting the left side of the steering gear to the crossmember Steering Gear Attachment To Crossmember (Left Side) to a torque of 58 N·m (43 ft. lbs.)
Attach power steering fluid, pressure and return lines into proper ports of the steering gear Power Steering Hose Connections At Steering Gear Tighten both power steering hose tube nuts to a torque of 47 N·m (35 ft. lbs.)
CAUTION: Before installing tie rods on steering gear be sure the tie rod spacer block inside the steering gear bellows Tie Rod Spacer Block is correctly aligned with the bolt holes in the rack of the steering gear and the steering gear bellows
Align center take off on steering gear with the tie rod assemblies. Install tie rod attaching bolts and washers into steering gear. Be sure washers are installed between tie rods and steering gear Tie Rod Attachment To Steering Gear Tighten the tie rod to steering gear bolts to a torque of 82 N·m (60 ft. lbs.)
