Mounting Location
Mounted on engine exhaust manifold. Positioned away from direct high heat; ensure oil/water lines and actuator hoses are clear, no kinks or interference.
Installation & Maintenance
1. Prep: Cool engine fully; clean intake/exhaust/oil surfaces—no carbon or debris.
2. Inspect: C3792214 no cracks, impeller damage; shaft end play ≤0.12mm, radial play ≤0.25mm.
3. Seal: Use new gaskets/O‑rings; lube oil ports with clean engine oil.
4. Install: Torque bolts evenly; connect oil lines before exhaust/intake.
5. Pre‑lube: Manually rotate and fill oil inlet to lube bearings before startup.
6. Test: Idle 3–5 mins; check noise, leaks, boost pressure.
7. Maintain: Inspect every 500 hrs; clean air filter every 1000–2000 hrs. Avoid rapid acceleration cold or sudden shutdown hot.
