Hi and thanks, I searched both numbers the A comes out as the 3.6 and the B returns books on amazon and LCD screens on ebay. I'm not sure it even exists for the 2.0 in that shape. The 2.0 cogs are much further apart than the 3.6.

No speciality tools were required. There are speciality tools if you want to pull the cams without removing the timing chain covers but if your goal is to replace the timing chain guides and tensioner it is straight forward. I would recommend also replacing the chains and lower chain assembly (guides, tensioner, etc) if you’re already going in there... essentially if you’re putting your hands on it, replace it (within reason). Chains stretch.

Hello. I have a 2020 Jeep Wrangler 2.0T that had the timing chain replaced under warranty at my local Jeep Dealership. After they completed the installation, they told me my Jeep battery died and they had to jump it off several times to get it to run.
When I arrived to pick up my Jeep, I noticed the young man used two different machines to attempt to jump my Jeep off and the Noco device was able to get the Jeep to start. I’m concerned the dealership having to jump my Jeep off multiple times, that it has damaged my new Timing Chain because the Check Engine Light came on after he jumped my Jeep off. The actual Tech that performed the installation claimed he didn’t see a Check Engine Light on when he finished the installation on the Timing Chain.

I also noticed when I got home that the two connectors that connect to my Air Box was unplugged and just hanging there in my Engine Bay behind the Air Box, so I disconnected the IBS and the two cables on the battery post for about 30 minutes and then, reconnected the two hoses in the picture until they clicked in place and then reconnected the battery cables and lastly the IBS. I was hoping this would make the check engine light go off permanently, but I won’t know until I drive my Jeep at least 50 miles and the check engine light reappears. When I used my Bluetooth OBD Reader it no longer had the series of codes for “low voltage”(Battery Voltage)like the Tech showed me at the dealership; but it still showed the “P1CEA” code which read “Boost Side EVAP Purge System Performance”.

My question is
1.) Where is the Boost Side EVAP Purge System located on a 2020, 2.0T Jeep Wrangler Rubicon? I would like to check it myself and make sure it is connected and not damaged.
2.) Also do you know if the dealerships are supposed to replace the “Primary and Secondary Timing Chain” along with the Fuel Line when they perform a Warranty Timing Chain Replacement?

I just want to make sure I have all my ducks in a row when I take my Jeep back, so I know what to point out. I’m also wondering if the timing chain was even installed correctly and if the timing is off by a tooth or two. I’ve never had my check engine light come on before. Jeep was bought new and I have had it for 5 years. Check Engine Light has only happened after they replaced my Timing Chain a few days ago.

The reason it had to be replaced is because I heard a metal, spinning, rattling noise when I would coast through my neighborhood or parking lot, but at highway speeds the sound would disappear. When I got my oil changed it went away, but at 45% Oil Life, the noise returned and this is when I took it to my trusted mechanic and he recommended the dealership to handle the Timing Chain under warranty before the PT Warranty expired.
Any helpful information or advice is welcomed and appreciated. Thank you.

Im wanting to have the timing chain tensioner replaced as im starting to hear that sound on startup on cold days so i know its only going to get worse. But i only have 45k miles on it and not sure its worth replacing all the other shit.. I just wonder cost wise. Also, Anyone in the South bay, Ca know a show that they would trust to change this out?

With the ticking noise happening. Is it possible to just replace the timing chain tensioner only?

Anything is possible, the question is whether or not it is prudent.

Hi all. I am considering an attempt and doing this myself too. Question. Did you take the front cover and radiator off for better access? Or did you just work in that tight spot to remove timing cover, etc. Did you ever find a video or instructions on doing this job? I found a video on an engine out of the car, but I didnt find one where they replaced parts while engine was in car.
