Curious about whether your 2008 Lexus GX470 has a timing belt or chain? Well, the GX470 actually comes with a timing belt. The purpose of this belt is to ensure that the camshaft stays in sync with the crankshaft, which in turn helps the engine's valves open and close properly. Depending on the specific belt you choose, the recommended replacement time for a timing belt can exceed 100,000 miles. If you do opt to replace the belt, be prepared for a cost of around $900, covering both parts and labor.
