The water pump is responsible for circulating the coolant through the engine to keep it at the proper operating temperature. When the water pump breaks, the coolant is no longer able to move and the engine can rapidly overheat.
Overheating can cause several severe problems, such as:
- Engine seizure: If the engine becomes too hot, the pistons can seize in the cylinders and the engine will no longer run.
- Cracked cylinder head: The extreme temperatures can cause the cylinder head to crack.
- Blown head gasket: The high pressure in the engine could cause the cylinder head gasket to break.
- Melted aluminum. Some engine components, like pistons, and transmission parts will melt.
If you suspect that your water pump may be broken, it is important to stop driving and have your car inspected by a qualified mechanic immediately. Do not attempt to drive your car any further than necessary without having the water pump repaired as this could result in catastrophic engine damage.
