Product Details

The Gates 31331 is a direct-fit OEM-replacement radiator cap engineered to maintain proper cooling system pressure and protect against coolant loss. Gates is a globally recognized leader in fluid-power and power-transmission products, and their radiator caps are manufactured to meet or exceed original equipment specifications.

Key Features:

  • Maintains correct cooling system pressure to raise the boiling point of coolant
  • Precision-calibrated pressure relief valve opens at the rated pressure to protect hoses, radiator, and water pump from over-pressurization
  • Vacuum relief valve allows coolant to return from the overflow/reservoir tank as the system cools down
  • High-quality sealing gaskets resist heat, pressure, and coolant chemicals for long service life
  • Direct OEM-replacement fit — no modifications required
  • Manufactured to Gates' strict quality and dimensional standards

A faulty or worn radiator cap is a common cause of coolant boil-over, overheating, and coolant loss. Replacing it with a quality Gates cap is a simple, cost-effective step in routine cooling system maintenance. Gates part number 31331 is designed for a precise, leak-free fit on compatible applications.
