Good morning,

Why are you replacing the tensioner? Is it making noise?

Usually you replace the chain at the same time.

Camshaft Timing Chain, Sprockets, and Tensioner Replacement

1. Disconnect the negative battery cable.
2. Remove the No. 1 cylinder spark plug. Refer to Spark Plug Replacement See: Spark Plug > Procedures.
3. Rotate the crankshaft in the engine rotational direction clockwise, until the No. 1 piston is at top dead center (TDC) on the compression stroke.
4. Raise and support the vehicle.
5. Remove the engine front cover. Refer to Engine Front Cover Replacement See: Timing Cover > Procedures.
6. Lower the vehicle.
7. Remove the camshaft cover. Refer to Camshaft Cover Replacement See: Valve Cover > Procedures.

Important: The timing chain tensioner must be removed to unload chain tension before the timing chain is removed. If not removed, the timing chain will become cocked and it will be difficult to remove.

8. Remove the timing chain tensioner.

No, this is done with the engine in the car.

It is a tight fit but you can get to the front of the motor from both the upper end and from down under the car.

A ticking sound?

Can you upload a video of the noise so I can hear it?

You will need a lot of basic hand tools. You will need a puller for the harmonic balancer and most likely an air gun or electric gun to release the bolt holding the balancer.
