The typical count is two VVT solenoids, though the exact number can vary with engine options and market specifications.
Variable valve timing (VVT) relies on oil-control valves to regulate cam timing. In 2017 Grand Cherokees, the common engines—3.6L Pentastar V6, 5.7L Hemi V8, and 3.0L EcoDiesel—use a two-solenoid setup to manage VVT across the relevant camshafts. This configuration is standard in North American models, but always verify against your vehicle’s VIN and factory documentation.
Engine options and VVT solenoid configuration
Below is a concise breakdown by engine to help identify the typical solenoid count you might encounter when diagnosing or ordering parts. Always confirm with your VIN and service manual.
- 3.6L Pentastar V6: Dual VVT with two oil-control valves (OCVs) — commonly described as two solenoids total, one for each bank’s VVT circuit.
- 5.7L Hemi V8: Dual VVT configuration, generally serviced with two OCVs (one for each bank).
- 3.0L EcoDiesel V6: VVT-enabled design that typically uses two oil-control valves to manage cam phasing.
Concluding note: In practice, two VVT solenoids cover the 2017 Grand Cherokee’s common engine configurations. If your vehicle has a market-specific option or unusual equipment, consult the factory service manual or a dealer to confirm exact parts for your VIN.
locating and diagnosing VVT solenoids
Solenoids are usually located on or near the valve covers, and failures can manifest as rough running, reduced fuel economy, or trouble codes related to cam timing. When diagnosing, technicians often scan for codes such as P0011 or P0021 and inspect the solenoids, connectors, and oil quality. Replacement typically involves disconnecting wiring, removing mounting fasteners, and installing new gaskets and seals.
Summary
For 2017 Jeep Grand Cherokee models, two VVT solenoids is the standard configuration across the common engine options. Engine choice and regional specifications can influence exact layout, so verify with the vehicle’s VIN and official manuals if you are replacing parts or performing diagnostics.
