The VVT solenoid simply pulls out once you unbolt it and the seal should come with it, so you won't have to worry about that part.

Here is a guide that will help with this:

You are going to have to remove the valve cover, so I included that for the right-hand side.

Let me know what other info you need, and I can provide that as well.

Thanks

Hi,

The VVT solenoid is under the valve covers, on each side. To access it, first determine which side the problem is located on (bank 1 or 2), remove the valve cover, and unbolt the solenoid.

The O-ring will likely be brittle and break. If that is the case, you will need to get a new one. Before installing the new O-ring, lubricate it with engine oil then slide it into place.

I attached the directions below for the removal and replacement. As far as cleaning, I would use something like mass airflow sensor cleaner or throttle body cleaner.

One last thought. There will be two connector pins in the solenoid. To check it, apply voltage and ground to the solenoid. It doesn't matter which pin gets the power. When you do this, make sure not to short the connectors. You should hear the solenoid actuate when power is applied. Battery voltage from the vehicle can work or you can even use a 9v smoke detector battery for the test.

Let me know if this helps or if you have other questions.

Take care,

Joe

Hello,

There are two variable valve timing solenoids on this engine. One under each valve cover. The valve covers will need to be removed in order to access the solenoid.
Most of the time the old sealant/gasket residue can be cleaned with a plastic scraper.

I have attached the complete procedure for the valve cover removal and the solenoid replacement below. It has all the torque specifications and torque sequencing.

Please let me know if you have any questions.
Thank you.
