171540This Toyota 2LT cylinder head assembly 171540 suits engines that start to lose power, run rough, or show signs of head damage. The casting sits clean, and the ports line up well with the 2LT layout, so installation doesn’t feel like a struggle.

Once fitted, the engine idles smoother and holds compression the way it should. It’s a practical replacement for technicians who want a direct-fit head that keeps the job straightforward.
This Toyota 2LT cylinder head assembly (171540) suits mechanics and owners who want a clean, workable replacement for a worn or cracked head. The casting follows the 2LT pattern closely, so the passages sit where they should, and the head bolts line up without forcing anything. Most workshops choose a full cylinder head assembly for engines that struggle with overheating, uneven compression, or rough starts—common issues on older 2LT diesel units.
When you unpack it, the first thing you notice is how the surface sits flat and ready for fitting. That saves time during assembly. Another thing worth noting is how the ports follow the original layout, which helps avoid airflow issues once everything goes back together. In most cases, technicians fit this head when the old one shows cracks between valves or around the injector seat.
