What causes a water pump gasket to fail?

Over time, heat and pressure can cause the gasket material to degrade, leading to cracks or tears. Contamination in the coolant or improper installation can also shorten the gasket's life.

Do I need to replace the water pump itself when replacing the gasket?

You only need to replace the gasket if the water pump housing is not damaged or leaking. Inspect the pump housing for any cracks or wear before installing the new gasket.

What is the benefit of laser-cut gaskets?

Laser cutting provides a very precise and clean edge on the gasket. This accuracy helps ensure a perfect seal against the mating surfaces, reducing the chance of leaks.
