The oil control valve (in 5.7) is a crucial component that plays a crucial role in controlling oil pressure and flow, thus ensuring stable vehicle performance. <\/p>\n\n\n\n
This component may occasionally become faulty and require cleaning or replacement. But it can be difficult for someone to identify the location of the oil control valve. <\/p>\n\n\n\n
Don’t worry; we’ve got you covered whether you want to clean or replace your 5.7 Hemi oil control valve.<\/p>\n\n\n\n
If you don’t know what you’re looking for, it will be almost impossible to find and identify the oil control valve. The VVT, or Variable Valve Timing solenoid works as the oil control valve on the 5.7 Hemi engine.<\/p>\n\n\n\n
The VVT oil control valve on a 5.7 Hemi engine is located underneath the intake manifold. So, to access the VVT oil control valve, you need to open the manifold and find the VVT solenoid connected inside it. You will see it held in with one 10 mm bolt.<\/p>\n\n\n\n
Variable valve timing systems are now standard in all contemporary vehicles to increase performance and fuel efficiency. It works in a simple manner. The solenoid valve regulates oil flow toward the camshafts using electromagnetism principles<\/a>.<\/p>\n\n\n\n The technology was developed to ensure that your engine runs perfectly while still providing reliable low-RPM performance. <\/p>\n\n\n\n The oil control valve, also known as the VVT solenoid, is linked to the engine’s control unit. The ECU sends power and signals to the solenoid to adjust valve opening and camshaft timing. <\/p>\n\n\n\n Thanks to this process, the engine can precisely control the oil flow through the channels to the phasers, allowing the PCM to adjust intake pressure and optimize fuel delivery into the combustion chambers.<\/p>\n\n\n\n Read Also:<\/strong> Why Does 5.7 Hemi Oil Pressure Drop at Idle? (Causes & Fix)<\/a><\/p>\n\n\n\n A faulty VVT solenoid or oil control valve can cause many problems for your engine. You can experience symptoms like poor engine performance, poor fuel economy, a rough idle, and so on. <\/p>\n\n\n\n In these situations, it is best to replace the solenoid with a new one. Follow the steps below to replace your faulty 5.7 Hemi VVT:<\/p>\n\n\n\n First, disconnect the battery to avoid damaging your car’s electrical system. Always start with the negative terminal of the battery.<\/p>\n\n\n\n Then you need to remove the connections from the intake manifold. Start by disconnecting the intake tube and vacuum line. Then it won’t be difficult to detach the push and pull clip injectors.<\/p>\n\n\n\n The manifold should be connected to the engine with eight 8-millimeter bolts. You can easily unbolt them with a ratchet. You may need to use an angle extension bar with the ratchet to access the hard angles. Then you can just pry off the manifold with a bar.<\/p>\n\n\n\n Locate the VVT solenoid on the engine. It is usually held in place by a connector and one 10 mm bolt. Use a 10 mm socket and a ratchet to remove the bolt that secures the VVT solenoid in place. After that, you can just gently wiggle and pry the VVT solenoid away from the engine. <\/p>\n\n\n\n Now take the new VVT solenoid and install it by aligning it with the mounting hole and pressing it into place. Use a 10 mm socket and a ratchet to reinstall the bolt that secures the VVT solenoid in place and reattach the connector.<\/p>\n\n\n\n Now you can lower the manifold. Reattach the bolts and connections again. Reconnect the injectors and vacuum lines.<\/p>\n\n\n\n Reconnect the negative battery cable and start the engine. Check for abnormal noises. If everything is working correctly, the repair is complete.<\/p>\n\n\n\nHow To Replace A Faulty Oil Control Valve In 5.7 Hemi?<\/h2>\n\n\n\n
