GMC Acadia timing chain replacement needed on GMC Acadia

Some GMC Acadia owners report experiencing concerns regarding timing chain replacement, including the need for professional assistance if they suspect issues with their timing chain. While the Acadia's timing chain is designed to last longer than a timing belt, some owners find it necessary to seek a certified professional for safe replacement. Additionally, there are reports that the timing chains can be replaced without removing the engine, but some dealers may need to address any cooling system leaks that arise during the process. The cost of replacement can vary significantly, with out-of-pocket estimates sometimes reaching around $875 beyond warranty coverage. Overall, while the timing chain offers durability and cost-effectiveness, owners should remain vigilant about potential issues that may require timely intervention.
