Step 1:
Step 2:
32mm Deep Socket, Ratchet
Remove the timing chain tensioner. It’s located on the RH (Passenger) side
front of the engine, just a little bit below the exhaust cam sprocket.
You can’t see it in this picture, but it’s down there, and easy to find.
There’s also plenty of room between the engine and body to get a socket
and ratchet in to loosen it up.
You’ll want to stuff an extra rag underneath because you’ll lose some oil
when you remove it.
Remove the old sealing ring, clean up the tensioner, and install the new
sealing ring. Set the tensioner aside for now.
