2000 Chevrolet Tracker Parts Questions & Experts Answers

• Q: How to inspect and maintain the power steering pump to ensure it functions properly on 2000 Chevrolet Tracker?

  A: A Power Steering Pump replacement should be performed when cracks or leaks appear on its body or cover and if it displays excessive wear. The maintenance check involves evaluating both the side plate together with the shaft for dangerous wear or damage which warrants replacement of the entire pump assembly. A thorough inspection of the cam ring should be performed for detecting wear and damage before deciding to replace the pump assembly. The sliding surfaces of rotor and vane must be checked for wear and damage through the Power Steering Pump seal kit. If wear or damage occurs the replacement is needed. Use a feeler gauge to measure vane-to-rotor clearance and keep the measurement between 0.015 and 0.027 millimeters (0.0006 to 0.0011 inches) or replace the rotating components in the Power Steering Pump seal kit. Check for blockages in the relief valve fluid pathway as well as in the connector orifice while examining the relief valve moving component for signs of wear or damage. Dial calipers should be used to measure the free length of the flow control valve spring which must fall between 19.0 - 22.0 mm (0.748 - 0.866 inch). Replacing the Power Steering Pump becomes necessary if the valve spring measurement does not follow these specifications.
