Does the 2018 Acura TLX have a timing belt or chain?

The 2018 Acura TLX2.4L engine has a timing chain, but the 2018 Acura TLX V6 has a timing belt. Chains tend to last the lifetime of a vehicle - unless something serious happens - where belts need to be replaced at some point no matter what. If You have the chain, You need to stay on top of oil changes at the recommended intervals, but also check Your levels at least once a month. Make sure they fall within the top and bottom lines on Your dipstick, and drain or fill as needed. If You have the belt, Acura suggests changing it every 60,000 to 90,000 miles. Unfortunately, the cost estimate to replace the belt is around $900 to $940.
