Rattle Sound near Front of Engine

The 2019 XT4 may have a rattle sound heard near the front of the 2.0L 4-cylinder engine (RPO LSY) due to a stuck or collapsed timing chain tensioner and, as a result, a loose timing chain.

If the rattle sound is heard near the front of the engine, remove the lower engine front cover assembly and inspect the timing chain tensioner. A stuck timing chain tensioner plunger will allow an air gap to be present between the tensioner plunger and the timing chain guide. (Fig. 23)

When viewing the timing chain tensioner removed from the engine, the plunger can be seen stuck in the body of the tensioner. (Fig. 24)

If these conditions are found, replace the timing chain tensioner following the appropriate Service Information.
