What happens if your timing belt is not replaced?
This may be rare but it can happen if your timing belt is not replaced timely. On some engines, incorrect timing or a snapped timing belt can lead to catastrophic engine damage. In so-called ‘interference engines’, it will mean that the pistons and valves will hit.
What happens if the timing belt snaps on an interference engine?
While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely. In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
How does the timing belt work on a Toyota?

From 1995 to 2004, Nissan Pathfinder cars with the VG33E engine are belt driven while the VQ35DE and ZD30DDti are chain driven. From 2005 to 2017, all pathfinders are chain driven.
What happens when the timing belt snaps on a car?
In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs. You just pop a new belt on, and the engine should theoretically drive normally.
Why does my timing belt make a squealing noise?
Over time the timing belt can and will wear. A squealing noise from the engine or a belt that looks frayed can indicate that your belt has worn too much. Often this is just because of normal wear, other times because of wear to parts like the pulleys or a tensioner, as a faulty pulley or tensioner can rip the timing belt.
Is the timing belt made out of rubber?
Your timing belt, also known as a cam belt, is an essential part of your car. Here’s why you need to keep it in good working order. The timing belt in your car is made out of tough rubber with grooves or teeth running along the inside edge.
Which is more important the camshaft or the timing belt?
Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.
