A broken timing belt on your Mazda b2500 engine can cause the following damage:
* Piston damage: The pistons in your engine can collide with the open valves when the timing belt breaks, causing significant damage.
* Valve damage: The valves in your engine can also be damaged if the timing belt breaks. The valves can bend, break, or be dislodged from their seats.
* Head gasket damage: The stress of a broken timing belt can also cause the head gasket to fail, which can lead to coolant and oil leaks.
* Timing belt damage: The timing belt will have to be replaced and possibly tensioners, idlers, water pump if they are driven by the timing belt.
* Camshaft and crankshaft damage: In some cases, a broken timing belt can also cause damage to the camshaft and crankshaft.
In short, a broken timing belt is a serious problem that can cause severe engine damage. If you think your timing belt has broken, you should stop driving immediately and have your vehicle towed to a mechanic for repairs.
