Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I don't see why not. The only one that is challenging to reach is the one on top. You'll have to remove the A/C compressor to get to it.
Pump up the new ones with oil before installing them.
I'm assuming you just mean the tensioner itself and not the ramps.
Yes BUT!
1. Take out the small cam end plugs there are four, usually Green.
2. Turn the engine to TDC (0) pin the belt pulley with 8mm (5/16") pin.
3. With special tool lock the cams in the bank the tool fits into.
4. Remove clean and install the tensioner only for the bank that is locked with the cam lock tool.
5. Remove cam lock after the tensioner is installed remove the pin from the pulley turn the engine one (1) revolution.
6. Insert pin in pulley.
7. Insert cam lock in the other bank.
8. Remove clean and install the tensioner only for the bank that is locked with the cam tool.
9. After installing the second banks tensioner you should be able to pull the IMS chain tensioner.
10. When the IMS tensioner is installed again remove the cam lock and pulley lock pin.
11. Turn the motor 1 revolution pin the pulley check the cam position One bank the special tool should fit the other it won't.
12. Turn the motor 1 revolution again the lock the crank with the pulley pin and other banks cams should fit the cam locking tool.
13. Install new cam end plugs.
I was able to remove and install the tensioner on the top side without removing the A/C compressor. It took a little work to install, pushing down while turning, but easier than removing the compressor. I used this tool configuration:
I was under the impression that if you have the 5 chain motor, you only needed to find TDC and pin the crank pulley, not remove the cam end plugs and lock them with the special tools as well....
