  Q: How to replace the power steering pump on a with A/C on Chevrolet Tracker?

  A:

  You must remove the A/C Compressor before changing the Power Steering Pump of your vehicle. Before hose detachment clean the pump housing thoroughly while you set down a drain pan to collect fluid runoff. First detach the Power Steering Reservoir and its attached outlet hose before disconnecting the pump fittings which lead to the power steering gear inlet hose . Begin by disconnecting the Power Steering Pressure Switch connector after removing the 2 gaskets and inlet hose followed by taking off the Power Steering Pump Drive Belt. The next step includes removing the Power Steering Pump by first removing the two securing bolts. Install the Power Steering Pump in its proper position and lock it with the two bolts which should be tightened up to 25 nm (18.5 ft. Lbs.). Reinstall the power steering gear inlet hose with both gaskets followed by the fitting which needs to be secured at 60 nm (43.5 ft. Lbs.). Install the power steering fluid reservoir followed by the outlet hose and clamp the hose to the pump. Back in position and secure both the A/C Compressor and Power Steering Pump Drive Belt after appropriate adjustments. Pour power steering fluid into the reservoir while performing power steering system bleeding to clear it from air pockets.

  Q: How to service and repair the power steering pump on Chevrolet Tracker?

  A:

  Start by removing the Power Steering Pump from the vehicle and clean its exterior until mounting it securely onto a table vise for service and repair. The service requires that you detach the power steering gear outlet hose connector bolt and the power steering gear outlet hose connector along with its o-ring. The pump body must lose its pressure switch along with its flow control valve. The service requires removal of the rear pump cover and o-ring seal by unscrewing bolts (1,2,3,4) before extracting the cam ring off the pump shaft while maintaining vane assembly order for reinstallation. The next step involves removing the rotor vanes and then taking out the snap ring followed by the rotor and side plate and o-rings. Pull the shaft with connected pulley before extracting the oil seal from the pump body. The inspection process should check the pump body and cover for any sign of cracking or leakage but any severe wear or cracks or leaks require replacement of the Power Steering Pump. The pump assembly must be replaced when you detect wear or damage on the side plate or shaft. Replace the pump assembly when detecting any problems with the cam ring inspection. Newsurface the sliding surfaces on the rotor and vanes then replace them with the Power Steering Pump seal kit when necessary. Use a feeler gauge to check the vane-to-rotor clearance which must remain between 0.015 - 0.027 mm (0.0006 - 0.0011 inch). If the customer finds a result outside this range then the Power Steering Pump needs new rotor and vane components from its kit. The fluid passage within the relief valve along with its connector orifice needs to be checked for any type of blockage while the relief valve's sliding surface must be checked for wear and damage. Use dial calipers to examine the free length of the flow control valve spring. It must fall between 19.0-22.0 mm (0.740-0.866 inch), otherwise replace the Power Steering Pump.
