Keeps Your Coolant Moving and Your Engine Running

Whether you're working on a construction site or sending fleets across the country, maintaining the proper engine temperature is critical to ensure your trucks, buses, and vehicular equipment run properly.

Our heavy-duty water pumps are designed for superior resistance to corrosion, chemicals, and high-operating temperatures, and they're tested to stand up to some of the most challenging applications in the industry.

Conducting Complete System Repairs

When your water pump fails, your vehicle engine can crack and seize up, leading to costly engine damage and unwanted downtime. We always recommend using OE-equivalent parts that are manufactured to your vehicle specifications. Your water pumps and cooling system components are designed to wear at about the same rate, so you'll want to Be System Smart by checking your cooling system, and other critical vehicle systems, at 60,000 miles and conducting a full replacement at 90,000 miles.
