No, No, and YES...!
No, not changing the timing belt doesn't effect performance or fuel economy of your car.
No, if it's not changed and if your Volvo engine is the single overhead cam type, it is a non-interference type engine and if you don't replace it then when the belt breaks, you'll be left by the side of the road, it's not really a roadside repair at several hours to replace....However being a non-interference engine it won't damage your engine when it does break.
Where it is a YES....If it's a dual overhead cam engine (like the 4 cylinder 16 valve) it is an interference engine. If you don't replace it at the recommended interval or risk not only ending up by the side of the road, when it does break you'll end up with an empty wallet to repair it.
The timing belt should be changed every 50,000 miles to avoid it breaking and leaving you stranded some place. The timing belt is located under the hood of the car near the engine.
On a 1994 Volvo 960, the timing marks are located on the engine's front. For the inline-six engine, you can find the timing marks on the crankshaft pulley and the timing cover. The marks align to indicate the correct timing for the engine's camshaft and crankshaft. It's essential to ensure that the marks are aligned accurately during timing belt replacement or adjustments to maintain engine performance.
To set the timing on a Volvo 240, first, ensure the engine is at operating temperature and then turn off the engine. Locate the timing mark on the crankshaft pulley and the timing pointer on the engine block. Start the engine and use a timing light to check the timing; adjust the distributor as necessary to align the timing mark with the specified degree (usually 12-16 degrees BTDC for the B230F engine). Finally, tighten the distributor hold-down bolt and recheck the timing to ensure it remains accurate.
According to the Gates website ( they make timing belts etcetera ) the 2.4 liter five cylinder engine in a 2006 Volvo S40 ( is NOT an interference engine )
The Volvo 850 does not have a non-interference engine. This means that if the timing belt breaks, then serious internal engine damage will inevitably occur.
everyone says it needs to be changed around 105,000 miles
Yes, the 2005 Volvo S40 is equipped with an interference engine. This means that if the timing belt fails, the pistons and valves can collide, potentially causing significant engine damage. Regular maintenance and timely replacement of the timing belt are essential to prevent such issues.
The 1990 Volvo 740 GLE is equipped with a B230F engine, which is considered a non-interference engine. This means that if the timing belt were to fail, the pistons would not collide with the valves, preventing severe engine damage. Regular maintenance of the timing belt is still crucial to ensure the engine operates smoothly and reliably.
The timing mark for the crankshaft on the 1989 Volvo 740 Turbo is typically located on the harmonic balancer. It should align with a corresponding mark on the engine block or timing cover when the engine is at top dead center (TDC) on the first cylinder. This alignment ensures proper timing for the engine's operation. Always refer to the service manual for specific details regarding your engine's configuration.
The 2007 Volvo XC90 is equipped with a timing belt rather than a timing chain. The timing belt is part of the vehicle's engine components and typically requires replacement at regular intervals, usually around 105,000 miles. It's important to follow the manufacturer's guidelines for maintenance to ensure engine longevity.
Depending on where you live, belt only and labor, $350 to $500.
The Volvo V70 with the 5244T3 engine is classified as a non-interference engine. This means that in the event of a timing belt failure, the engine's pistons and valves will not collide, preventing potential catastrophic damage. However, it's always recommended to maintain the timing components to avoid unexpected failures.
