The 2007 Volvo XC90 has a timing belt that is crucial for controlling the engine's timing. It is recommended to have the belt, tensioner, and idler pullies serviced at 120,000 miles. While the belt itself typically lasts longer than the vehicle, the tensioners and pullies are more prone to failure. If these parts fail, it could cause the belt to shift gears, leading to severe impact on engine performance and potential damage. The belt links the crankshaft and camshaft, ensuring that the valves align properly with the pistons. If the engine's timing is thrown off, there is a risk of piston-valve collision, resulting in valve damage.
In fact, the 3.2-liter 2007 Volvo XC90 is equipped with a timing chain.
The 2007 Volvo XC90 is equipped with a timing belt that typically requires replacement every 60,000 to 100,000 miles as part of routine maintenance. Neglecting to replace the timing belt on schedule is a common cause of related issues.
