Heavy Duty Radiator Caps for Kenworth Trucks

You should match the cap by pressure rating (measured in PSI), neck diameter, and model compatibility. For Kenworth trucks such as the T2000, referencing your OEM part number or contacting Radiator Supply House with your truck's make, model, and year ensures you receive a correctly fitting, OEM-equivalent radiator cap.

Most heavy duty Kenworth truck cooling systems operate at a pressure rating between 13 and 20 PSI. The correct rating depends on your specific engine and cooling system design. Always consult your Kenworth service manual or contact a cooling system specialist to confirm the correct pressure rating before replacing your radiator cap.

It is generally recommended to inspect the radiator cap every 30,000 miles or at each major cooling system service interval. Heavy duty commercial trucks operating in extreme heat, off-road, or high-load conditions may require more frequent replacement. A cap that no longer maintains proper pressure should be replaced immediately to prevent overheating.

Yes. A worn or faulty radiator cap may fail to seal properly, allowing coolant to escape through the overflow tube or leak around the cap seal. In heavy duty trucks like Kenworth models, this can lead to low coolant levels, overheating, and potential engine damage if not addressed promptly.

High-quality aftermarket radiator caps, such as Radiator Supply House's ICEBOX replacement parts, are engineered to OEM-equivalent standards. They are designed to meet the same pressure ratings and fitment specifications as original equipment, making them a cost-effective and dependable option for commercial trucking fleets and repair shops.
