Infiniti Timing Belt Replacement Intervals

Please note: All of these belts are for an Interference engine.

IMPORTANT: A timing belt failure on vehicles equipped with interference engines presents a somewhat different scenario. This type of engine does not allow for clearance between a valve at its lowest point and a piston at its highest point. The critical link to ensure that these components do not collide is the timing belt. If an interference engine's timing belt fails, not only will the motorist be stranded, but additional damage to valves, pistons, cylinder head and cylinder walls can occur which can greatly escalate the cost of repair. It is essential to remember that when changing the timing belt, the timing belt system tensioner and pulleys must be examined to determine if they exhibit signs of wear or damage. If so, these components should immediately be replaced. Please look for ** to indicate interference engines. For extra assurance, please check with your mechanic or car dealership to determine if your vehicle has an interference engine.
