Installation Notes

Verify engine code, OE reference, and vehicle fitment before installation. Inspect the timing chain, guides, and related valve train components at the same time, since tensioner service is often performed as part of a broader timing drive repair. Follow BMW service procedures for torque values, priming, and timing alignment.
