How to Replace the Power Steering Pump on a '99 Chrysler Concorde 2.7

Updated July 20, 2017

The power-steering pump on a 1999 Chrysler Concorde 2.7 litre engine supplies pressurised power-steering fluid to the rack. The pump is located in a bracket attached to the engine and is driven by the serpentine belt. Over time the seal, bearing and other parts of the pump might wear out, causing fluid leaks. If you notice a loss of power steering, or you hear a screeching or squealing noise from the engine compartment while turning the steering wheel, it might be time to replace your power-steering pump. Experienced home mechanics can do the job in a series of steps.

Disconnect the Concorde's negative battery cable from the terminal using a wrench. Find the steering fluid reservoir.

Remove much of the fluid as possible from the steering-fluid reservoir, using the siphon pump. Slide the waste oil pan under the vehicle. Disconnect the power-steering return hose from the reservoir and let the power-steering fluid drain from the reservoir and power-steering pump into the waste oil pan.

Remove the power-steering fluid pressure hose from the fitting on the power-steering pump and let the remaining fluid drain from the pump. Remove the drive belt by loosening the adjuster bolt on the alternator with a socket. Slide the alternator toward the engine. Remove the belt by pulling it off the pulleys.

Remove the three power steering mounting bolts. Take the power-steering pump and pulley out of the vehicle as an assembly. You can do this by pushing the sleeve forward in the tensioner bracket until it is flush with the back side of the tensioner bracket, using a long flat screwdriver between the power-steering pump and the sleeve in the tensioner bracket.

Put the assembly in a vice and remove the pulley from the front of the power-steering pump assembly, using the special pulley puller. Use the same tool to replace the pulley on to the new power-steering pump.

Install the new power-steering pump back in the mounting bracket. The long mounting bolt is installed in the location where the sleeve is in the tensioner bracket. Loosely install the three mounting bolts for the power-steering pump to the bracket. When you tighten the power-steering mounting bolt that goes through the sleeve, ensure the sleeves are fully seated against the power-steering pump.

Torque the power-steering pump mounting bolts to 250 inch pounds. Install the drive belt on the power-steering pump pulley and alternator, then pull it tight with long a screwdriver and tighten the bolt.

Connect the power-steering pressure hose on the power-steering pump fitting. Torque the hose fitting to 35 foot pounds. Connect the power-steering return hose on the power-steering fluid reservoir.

Clean the battery post and cable end with a wire brush. Connect the battery end and tighten it with a wrench. Refill the power-steering system with power-steering fluid and bleed the system by turning the steering wheel back and forward until all the air is out. Check the power-steering fluid and fill if necessary.
