Editing Ford Explorer (section)

====Timing chain====
The 4.0&nbsp;L SOHC V6 engine found on second, third, and fourth generation Explorers was notorious for the plastic [[Original equipment manufacturer|OEM]] timing chain guides, cassettes, and tensioners breaking resulting in timing chain ticking, rattle or "death rattle". This problem can occur as early as 45,000&nbsp;mi (72,000&nbsp;km) in some vehicles. When the engine is running for an extended period of time with this issue, the engine can jump timing or cease running, damaging the heads and valves.

Timing chain rattle was mitigated in later years of the SOHC (in most vehicles, after 2002) with updated cassettes and tensioners.<ref>{{cite web|url= https://www.underhoodservice.com/exploring-service-needs-on-the-ford-4-0l-v6-engine/ |date=April 15, 2013 |title='Exploring' Service Needs On The Ford 4.0L V6 Engine|first=Larry |last=Carley |work=Underhood Service |access-date=July 21, 2019}}</ref>
