2009 Toyota Yaris Drive Belt Parts Q&A

• Q: How to install the fan and generator Drive Belt on 2009 Toyota Yaris?

  A: The proper installation of fan and generator V belt for the 1NZ-FE engine starts by inserting the belt provisionally onto each pulley while allowing it to fit properly into the rib groove. The correct tension for the belt can be achieved by inserting an adjusting bar between the engine mounting bracket and generator assembly which pushes the components towards the vehicle front. The installation process requires avoiding placement of the bar between the camshaft timing oil control valve assembly and generator assembly to avoid any damage occurring. Begin tightening bolt A to 19 Nm (189 kgf-cm and 14 ft-lbf) before proceeding to bolt B tightening until it reaches a torque of 54 Nm (551 kgf-cm and 40 ft-lbf). Check V belt deflection together with tension before making adjustments when required. The proper deflection measurement should be conducted at the designated point while you should adjust the tension to match the prescribed value when working with a new belt. Perform the belt installation procedure according to the values from used belt specifications for belts subjected to usage exceeding 5 minutes. A V-ribbed belt tension and deflection measurement should occur after two engine cranking revolutions while checking the belt tension gauge accuracy against a master gauge. Place the engine inside the under-cover area on the right-hand side as the last step.
