Toyota Cylinder Head 3VZ assembly 171544
171544This Toyota 3VZ cylinder head assembly 171545 suits engines that start to lose power, misfire, or show gasket damage. The casting sits clean, the ports line up well, and the head comes ready for workshop installation. Mechanics often choose this assembly when the old head cracks or overheats, since it fits straight into the 3VZ layout without extra adjustments. It supports stable engine running once the rest of the top end goes back into place.
This cylinder head assembly fits the Toyota 3VZ engine, and most workshops pick it when the original head starts causing trouble—things like coolant loss, uneven compression, or that familiar ticking sound when the top end wears out. The casting sits flat, and the surface holds the gasket well, which matters a lot on these V6 engines.
You drop it into place and the bolt pattern lines up without fighting it. The ports follow the 3VZ design closely, so airflow sits where it should. Another thing worth noting is how clean the machining looks; it saves time during assembly because you don’t end up reworking surfaces or chasing alignment issues.
Most mechanics choose this head when they want a straightforward replacement that fits the 3VZ layout. It suits daily-use vehicles as well as older engines that need a fresh top end to keep running smoothly.
