Product Details
Gates Heavy-Duty Radiator Caps are engineered for demanding cooling system service on heavy-duty equipment. This cap is sized for a 2.13 in. filler neck inside diameter and a 2 in. filler neck outside diameter, with a 1.14 in. cap depth and 2.81 in. shell diameter. The silver stainless steel finish resists corrosion, while the rubber sealing elements support a secure fit on open cooling systems. If you are replacing a worn radiator cap on a truck, bus, or tractor, Gates 31307 offers the correct heavy-duty B size configuration.
This part cross-references Four Seasons 46018 for the same application.
What It Helps Address
- Coolant loss from a worn or weak radiator cap seal
- Pressure control issues in an open cooling system
- Improper fit on a 3/4 in. deep filler neck
- Corrosion-related cap deterioration
- Venting problems in heavy-duty radiator service
Installation Notes and Tips
Verify the filler neck depth, inside diameter, and outside diameter before installation. This cap uses a cam-on attachment and is not a lever-type design. Confirm that the cooling system is an open system and that the pressure requirement matches the 4 psi rating before replacing the cap.
Quality Assurance
Gates identifies this as an OE exact heavy-duty radiator cap replacement. The stainless steel and rubber construction is specified for heavy-duty cooling system service, and the part number 31307 is listed for direct replacement use in the correct B size filler neck application.
