Does the 2012 Acura TSX 4 cylinder have a timing belt or chain?

Yes, the 2012 Acura TSX4Cylinder has a timing chain, not a timing belt. This is a good thing since it means You should never have to replace the chain - unless something serious happens to it. To avoid that, the best thing You can do is stay on top of Your recommended oil change intervals. For Your car, You should change the oil and the filter when Your Maintenance Minder tells You to, which will pop up on Your Multi-Information display. The cost to have Your car serviced for oil change maintenance will be in the range of $80 to $100. If You would like to save some money, You can also do it YourseLFAt home, since the process is fairly fast and easy.
