At what mileage does the timing chain need to be replaced? jeep wrangler 2008,3.8 L 6 cil.80,000 miles
You change the timing chain now when your Jeep has indicated from a check engine light on. The timing chain in engines these days last as long as the engine will, there is a timing chain tensioner to ensure there is no slack.
When the timing chain has gotten stretched to much, your Jeeps PCM will indicate that with a check engine light on your dash and will be indicated with a DTC codes from a scanner.
So no worries about replacing your timing chain and keep up the regular maintenance, if you have a Mechanic tell you other wise, there just looking for money and your looking for more then just a timing chain being replaced.
You can bet that chain, chain tensioner, timing gears, water pump and might even throw in a cam replacement will be in his recommendation.
Thank you for using fixya and be safe.
