2003 Toyota Tundra Parts Questions & Experts Answers

• Q: How to service and repair the power steering pump on 2003 Toyota Tundra?

  A: You must start power steering pump servicing or repairs by removing the air cleaner assembly through MAF meter connector disconnection and hose removal with clamp detachment then removing the three associated bolts. Detach the return hose by removing its clip while paying attention to prevent fluid from dripping onto the drive belt. Use care to disconnect the connector and unscrew the pressure feed tube's oil pressure switch then remove it from the tube without letting it drop onto the floor. Obtain a new supply of the switch in case of damage. The pressure feed tube needs disconnection through removal of the union bolt and gasket from the PS vane pump assembly. Users must begin installation of the drive belt by loosening bolt "A," nut "B," and finally bolt "C." The PS vane pump assembly can be removed by extracting bolt "A," nut "B," and the complete assembly structure. The PS vane pump assembly installation begins with bolt "A" and nut "B" temporary tightening followed by drive belt installation through bolt "C" tension adjustment before torquing bolt "A" and nut "B" to 44 Nm (450 kgf-cm, 33 ft. lbs.). The pressure feed tube installation requires proper connection which positions the stopper against the PS vane pump body followed by the application of a new gasket together with the union bolt installation, torquing to 46.5 Nm (475 kgf-cm, 34 ft. lbs.). Install the oil pressure switch onto the pressure feed tube by torquing it to 20.6 Nm (210 kgf-cm, 15 ft. lbs.) while being careful to avoid oil contact on the switch. You must use the clip to attach the return hose before reinstalling the air cleaner assembly by securing it first with the hose along with three bolts before securing the clamp followed by reconnecting the hose and MAF meter connector. Complete power steering system bleeding as the final task.
