Replace a worn exhaust camshaft phaser with a brand-new Dorman - OE Solutions VVT Sprocket / Camshaft Phaser, part number 916-552. It is a direct replacement for the exhaust position and fits many vehicles, among them the 2011-2020 Ford F-150 3.3L / 3.5L / 3.7L, 2011-2023 Ford Explorer 3.3L / 3.5L and 2011-2017 Ford Mustang 3.7L. Dorman lists this part under both names, VVT sprocket and camshaft phaser (a variable timing camshaft gear).
The variable valve timing sprocket plays a key role in engine performance and clean running. If a worn factory VVT sprocket is the cause of lost performance, this one replaces it and is designed to install and perform like the original.
- Direct replacement: fits and performs like the original sprocket.
- Durable construction: made from durable steel and precision machined for reliable performance.
- 100% new: an entirely new variable valve timing sprocket.
- Quality assured: validation tested for its vehicle-specific application.
Specifications: exhaust position; steel; silver in color; bolt-on attachment; outside diameter 3.59 in; inside diameter 0.47 in; overall height 2.64 in. The bolt and wiring harness are not included. Consult the vehicle service information for the correct bolt and whether the original may be reused. The package contains one sprocket, and the listed applications use a quantity of 2. Country of origin: China.
Signs this part may need replacing: a rattle from the timing area at startup, a check engine light with camshaft timing codes, rough idle, or reduced performance. Diagnose the cause before replacing, because other components can produce these symptoms.
