HD Engine Water Pump
GMB knows water pumps inside and out. Drawing on decades of water pump manufacturing and engineering experience, each water pump is manufactured to strict OEM specifications of quality, design, and fitment to ensure a high-quality finished product that is made to last. In fact, GMB provides water pumps to OE car makers including Hyundai, Kia, GM, and Chrysler. Enjoy the perks of having an OEM-quality water pump in your vehicle without the high price tag!

Features & Benefits:
  • 100% factory tested for leakage and dimensional precision
  • Designed to match OE coolant flow rate and pressure
  • Built with high-quality GMB bearings
  • Bearings are noise and durability tested
  • Built with exact OEM dimensions
  • Includes all required hardware for installation
Every belt driven water pump has a weep hole that might leak a little in the beginning. Some seepage from the weep hole is normal during the break-in period (about 10 minutes), and does not indicate a defect.
Cooling System Maintenance | Tips & Tools

Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:

  • Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
  • Consider replacing the Radiator Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
  • Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
