The water pump market is evolving fast, with millions of vehicles relying on mechanical or electric water pumps to stay cool and perform at their best.
Mechanical water pumps still dominate most vehicles. However, as OEMs continue to incorporate start/stop systems, hybrids, and electric drivetrains, electric water pumps (EWPs) have gained ground and present real service opportunities for the aftermarket.
When looking for a quality supplier, verify that the pump is thoroughly tested. Also confirm the pump meets OE fit, form and function. Choose suppliers that work with OEMs.
Finally, ensure high-quality materials are used since water pumps face corrosive environments. You want a pump that will last.

Dayco’s electric pumps are direct-fit, bolt-on replacements, so no modifications are needed during installation. They feature self-lubricating, corrosion-resistant bearings compatible with all engine coolants and tapered motor brushes for faster break-in. They also use high-strength seals to prevent leaks.
Installation Best Practices for Electric Pumps
Now let’s talk through four installation best practices, as some common mistakes can happen during EWP replacement.
First, remind your shop customers to flush the system completely to remove any residual contamination. Use a 50/50 mix of the correct coolant and distilled water.
Second, remind customers that reusing old seals or gaskets can cause leaks. Offer to add new gaskets and seals when doing a water pump replacement.
Third, ask the shop if they need a belt, tensioner and pulley when replacing the pump. A systems approach is best since components perform better when replaced together.
Fourth, tell shops that voltage checks are critical when installing electric pumps. Check voltage and grounding before and after. Low voltage can quickly destroy a new pump.
