Choosing between OEM and aftermarket water pumps depends on several factors:

OEM Water Pumps:

Pros: Guaranteed fit and compatibility, higher quality standards, better durability, and typically come with manufacturer warranty.

Cons: More expensive and may have longer wait times if imported.

Aftermarket Water Pumps:

Pros: More affordable and readily available in Pakistan, offering a cost-effective solution.

Cons: Quality varies widely some may fail prematurely o r not perform as well as OEM parts.

Risk of compatibility issues o r shorter lifespan.

Recommendation: For a high-end car like the Mercedes-Benz S-Class, it’s generally advisable to invest in OEM water pumps o r high-quality branded aftermarket parts from reputable suppliers to ensure reliability and avoid repeated failures
