• Q: How to install the fan and generator Drive Belt on 2010 Toyota Yaris?

  A: The first step of installing fan and generator V belt on 1NZ-FE engine requires placing the belt provisionally onto each pulley while checking for foreign substances and liquid free surfaces and proper belt fit into pulley rib grooves. Adjust generator V belt tension by inserting an adjusting bar between engine mounting bracket and generator assembly then pull the bar toward the vehicle front. Placing an adjusting bar between the generator assembly and camshaft timing oil control valve assembly is prohibited because it could cause damage to occur. Bolt A requires tightening to 19 Nm (189 kgf-cm, 14 ft-lbf) followed by adjusting bolt B to 54 Nm (551 kgf-cm, 40 ft-lbf). Check V belt deflection and tension by following the correct procedure when engine temperature is low; do this immediately after new belt installation or cranking the engine for used belts. Value the maximum deflection during a belt measurement between specified pulleys before setting new belt tension to the middle of its specifications. When employing a belt for more than five minutes the operator must apply used belt specifications while performing belt reinstallation by setting both deflection and tension at their intermediate specification values. The engine must crank for 2 revolutions to check V-ribbed belt tension and deflection before performing a master gauge confirmation of the tension gauge accuracy. Install the engine underneath the cover on the right-hand side as the final step.
