Hello, everyone. I am looking for input from long time members. I need to replace my timing chain tensioners on my 2011 KK @ 127k. Question #1 How much time does it take you to do this job? Question #2 Who makes a durable tensioner? Question #3 Should I just do the entire set using Cloyes parts or can I get away with just replacing the tensioners? (Driver side upper tensioner is the one giving me problems/broken) I ask because I don't have much experience on American products, especially Chrysler. I worked mostly on Nissan junk and tensioners have always been a problem but you can change just the bad tensioner and be just fine. I am planning to do the same here unless input dictates otherwise. If it was a VVT engine I would certainly change the chains but it's not so I'm looking forward to your opinions/advice. Thank you

Well I guess for lack of opinions/advice I am going to just do the whole kit and kaboodle. I am not looking forward to it but alas it has to be done.

Never done one yet John, so this may not be your answer.

To me, If you want the quick and dirty fix, just replace the tensioner. From what I’ve seen before, the chains do not SEEM to wear much. Kind of hard to tell in a vehicle that uses tensioners unless you lay a new chain and used chain on top each other. If the plastic guides are used on KK, I’d be thinking guides and tensioners unless I had a reason to go further.

Thank you for the reply and input. I finally settled on Cloyes timing chain and tensioner set. I am going to reuse the gears and sprockets. The deciding factor was being able to hear the chain riding against metal, it sure escalated quickly. It's parked now. Also, doing the water pump, thermostat, and radiator hoses plus an engine flush and oil change to remove any sparkling the chain and guide decided to contribute. Oddly despite the computer advancing the timing over 30 degrees shown in my Autel it hasn't misfired or kicked out a check engine light or code. It seems content to keep running towards its demise, but I can't have that. Lol

I used the Cloyes guides when I did the headgaskets on my 02 many years ago. The one OE guide fell apart when I disassembled for head removal. They did have about 160k on them. The Cloyes guides worked great for me.

Just a quick update. Got the Jeep apart. At first I was disappointed because at first glance everything looked up to *****. Alas, I found the problem. The primary chain was stretched. So I'm glad I'm doing the job despite it being a pita. Also found my evap leak, and my timing cover was leaking too with a failed coolant gasket internally, yikes!! Probably calling it a night tonight and reassemble it tomorrow. Already did the hard part of resetting the timing. Will update again when done
