Gates Radiator Cap P/N:31508
Keep your cooling system sealed and pressurized with the Gates Radiator Cap 31526. This OE-type standard cap seats on the radiator filler neck and holds system pressure so the coolant can reach a higher boiling point, while application-specific vent and vacuum-relief valves let coolant draw back as the engine cools. It's a direct-fit replacement across a wide range of applications, including the 1960-1962 Chevrolet Suburban 3.8L / 4.3L / 4.6L — see the "Vehicles it fits" section for the full list.
Additional specs: shell outside diameter 2.33 in, cap depth 1.25 in, filler neck depth .75 in (19 mm). The coolant recovery system is optional on the listed applications. Country of origin: China.
What pressure is the Gates 31526 rated for?
It's a standard cap rated at 7 psi (6-8 psi range), using application-specific vent and vacuum-relief valves for precise pressure control.
Will this radiator cap fit my vehicle?
It's cataloged for a wide range of applications, such as the 1960-1962 Chevrolet Suburban 3.8L / 4.3L / 4.6L. Check the "Vehicles it fits" section to confirm your exact year, make, model and engine.
Is the cap made of metal or plastic?
Gates builds these caps from corrosion-resistant, heavy-gauge metal or high-quality plastic depending on the application, so the material varies by fitment.
What are signs a radiator cap may need replacing?
Coolant loss, overheating, a cap that won't hold pressure, or coolant failing to draw back from the recovery tank can indicate worn cap seals or valves. Diagnose the cause before replacing.
Does the cap need any adjustment or a coolant recovery system?
No adjustment is required for installation. On the listed applications the coolant recovery system is optional.
