Does a 2017 Chevy Equinox have a PCV valve?
Yes. The 2017 Chevrolet Equinox uses a PCV (Positive Crankcase Ventilation) valve as part of its crankcase ventilation system. The exact placement can vary by engine option, but it is typically mounted on or near the valve cover with a hose leading to the intake manifold.
In more detail, PCV valves regulate the flow of crankcase gases back into the engine to be burned, reducing emissions and preventing pressure buildup. A failing PCV valve can cause symptoms like rough idling or oil consumption, so understanding whether your Equinox has one and where it sits can help with maintenance and troubleshooting.
Engine options and PCV layout
GM offered multiple engines in the 2017 Equinox. The PCV system is standard across these engines and uses a PCV valve or a similar valve integrated into the hose assembly to regulate vacuum and route crankcase gases into the intake. For most configurations, the valve is mounted on the valve cover and connected to the intake manifold by a short hose. Exact layout can vary by engine code and production variation.
- 2.4L Ecotec inline-4 (the most common engine in the 2017 Equinox): PCV valve located on the valve cover, typically toward the rear, with a hose to the intake manifold.
Note: Always verify with the service manual for your exact VIN, as layout can vary by engine and production batch. If in doubt, a quick under-hood inspection or a mechanic’s confirmation will ensure you locate the correct component.
Maintenance and troubleshooting
Before discussing steps, here are the typical maintenance and troubleshooting scenarios for the PCV system on a 2017 Equinox.
- Symptoms of a faulty PCV valve include rough idle, hissing noises under acceleration, increased oil consumption, or a check engine light related to crankcase ventilation. If you notice these signs, inspect the PCV valve and related hoses.
- Inspection and replacement steps commonly involve locating the valve on the valve cover, removing the valve, and performing a shake test: a good valve typically rattles; a stuck or clogged valve may not.
- When replacing, use an OEM or equivalent PCV valve and inspect the associated vacuum hose for cracks, stiffness, or deterioration. Replace hoses if they show wear, to avoid leaks and vacuum loss.
Concluding, a healthy PCV system contributes to proper engine vacuum, reduced emissions, and cleaner oil. If you suspect a PCV issue on your 2017 Equinox, check the valve and hoses, and replace as needed to restore smooth operation.
How to locate and verify the PCV valve on your 2017 Equinox
With the hood open and the engine cold, look for the PCV valve on or near the valve cover. The valve is connected to a small vacuum hose that leads to the intake manifold or throttle body. If you cannot easily locate it, consult the owner’s manual or a service manual for your exact engine code and VIN, or have a technician confirm the placement.
In practice, locating and checking the PCV valve is a straightforward maintenance task that can prevent larger engine problems if the valve sticks or a hose leaks. Regular inspection during routine maintenance can help keep your Equinox running smoothly and within emission standards.
Summary
The 2017 Chevy Equinox does include a PCV valve as part of its PCV system. The valve is usually mounted on the valve cover and connected to the intake manifold, though exact placement can vary by engine type. Regularly inspecting and, if needed, replacing the PCV valve and its hoses can prevent rough idle, oil consumption, and emissions issues. Always consult the vehicle’s service manual or a qualified technician for your specific engine code and VIN to confirm the exact location and replacement procedure.
What are the symptoms of a failing PCV valve?
Symptoms of a failing PCV valve include rough idling, engine misfires, and a rough acceleration, as well as increased oil consumption and visible oil leaks. You might also notice a whistling or hissing sound from the engine, a lit check engine light, and discolored exhaust smoke.
Performance issues
- Rough idling and acceleration: A failing PCV valve can cause an imbalance in the air-fuel mixture, leading to these issues.
- Engine misfires: A faulty valve can disrupt the air-fuel mixture, causing the engine to misfire.
Engine and oil problems
- Increased oil consumption: If the valve is stuck open, it can suck excessive oil into the intake manifold.
- Oil leaks: Pressure buildup from a clogged valve can force oil out of seals and gaskets, causing leaks.
- Discolored exhaust smoke: This can be a sign of oil being burned in the engine.
Other indicators
- Noises: A hissing or whistling sound coming from the engine is a common symptom.
- Check engine light: The check engine light may come on due to the various issues a faulty PCV valve can cause.
- Increased fuel consumption: This can occur if the valve is stuck open and causing performance issues.
What is the lawsuit on the 2017 Chevy Equinox?
Class actions have been filed regarding the 2010-2017 Chevrolet Equinox SUVs equipped with 2.4-liter Ecotec engines. One lawsuit claims the Ecotec engine burns too much oil and causes low oil pressure, knocking, fouled spark plugs, damage to the timing chains and complete engine failure.
Does a 2017 Equinox have a PCV valve?
PCV Valves for Your 2017 Chevrolet Equinox
Positive crankcase ventilation (PCV) valves are designed to recirculate combustion fumes from the crankcase into the intake so they can be burned again, resulting in lower emissions.
What's the most common problem with the Chevy Equinox?
The most common issues include:
- Excessive oil consumption: Many owners report the engine rapidly burns or leaks oil, requiring frequent top-offs and risking severe engine damage if not closely monitored.
- Timing chain failure: Early timing chain wear or breakage can cause catastrophic engine damage and sudden breakdowns.
