Toyota 1KD Cylinder head assembly 171547
171547This Toyota 1KD Cylinder Head Assembly (171547) suits engines that start showing the usual top-end problems—rough idle, slow pickup, or that familiar loss of compression after overheating. The head sits on the block without alignment trouble, and the ports follow the original 1KD pattern, so technicians don’t have to fight with mismatched surfaces or odd angles during assembly.
Anyone who works on 1KD engines knows they run hot, especially in heavier vehicles. Once the old head starts cracking between valves or lifting near the fire ring, repairs stop being worth it. Installing a fresh head makes the job straightforward again. Another thing worth noting is how evenly the gasket surface sits; it reduces the kind of uneven clamping that usually causes repeat failures.
What Makes This Head Practical for 1KD Rebuilds
- Fits the Toyota 1KD engine layout without modification
- Bolt holes and coolant passages line up cleanly during installation
- Supports stable compression for smoother running
- Helps resolve overheating damage, head warpage, and sealing issues
- Suitable for general workshops, fleet maintenance, and direct replacement jobs
In most cases, technicians want a head that doesn’t slow them down. This assembly works well for that. It sits neatly, torques down evenly, and pairs with standard 1KD top-end components. Once installed, the engine usually settles into a much cleaner idle and stops burning coolant or dropping power.
Acme Impex checks castings and machining before dispatch, so the head arrives ready for assembly without extra prep. If you're replacing a damaged 1KD cylinder head and want something that fits, works, and supports a solid rebuild, this assembly is a practical option for long-term use.
