Peterbilt 567/579 Radiator Tubes, Gaskets & Hoses
Replace Worn-Out Radiator Parts
These parts arenât just extrasâtheyâre essential. Radiator tubes move coolant from the engine to the radiator. Hoses carry that coolant through the system. Gaskets keep everything sealed tight, preventing leaks and pressure loss. When any of these fail, youâre looking at overheating, breakdowns, and expensive downtime. Thatâs why we carry heavy duty, long-haul-tested parts designed to handle high heat, pressure, and vibration. In this category, youâll find plenty of replacement components like: - Radiator tubes that deliver reliable coolant flow - Silicone and EPDM hoses for heat resistance and flexibility - Sealing gaskets built to lock in pressure and prevent leaks Consider additional replacement engine cooling parts like Peterbilt AC driers and compressors, or Pete 567/579 charge air coolers. You can also find a full Peterbilt 567/579 radiator replacement. Whether you're replacing worn components or upgrading for peace of mind, these aftermarket parts are made to fit your Peterbilt 567 or 579 and keep your cooling system in top shape.Frequently Asked Questions About Peterbilt 567/579 Radiator Tubes, Gaskets & Hoses
What are the differences between OEM and aftermarket radiator hoses for my Peterbilt 567/579?
OEM hoses are manufactured to exact factory specifications and typically use EPDM rubber rated for temperatures up to 275F. Aftermarket options vary in quality - premium aftermarket hoses often match or exceed OEM specs with reinforced fabric layers and similar temperature ratings, while economy options may use standard rubber compounds rated for 225F. For heavy-duty applications or extreme climates, we recommend sticking with OEM or premium aftermarket brands that specify compliance with SAE J20 standards.
How do I know which radiator tubes and hoses fit my specific Peterbilt model year?
Peterbilt 567 models from 2014-2018 and 579 models from 2013-2017 share many common radiator components, but there are critical differences. Models with EPA 2017 engines require different upper radiator hoses due to revised coolant routing. Check your VIN's 10th digit for the model year, and verify your engine type (Paccar MX, Cummins ISX, or Cat) as each requires specific hose configurations. Our part numbers include compatibility notes, but when in doubt, provide your full VIN for accurate matching.
What tools and skills do I need to replace radiator hoses and gaskets myself?
Basic replacement requires standard hand tools: hose clamp pliers, flat and Phillips screwdrivers, and a drain pan capable of holding 12-15 gallons. The job typically takes 2-3 hours for experienced DIYers. Key challenges include accessing lower hoses (may require removing splash shields), properly bleeding air from the cooling system, and achieving correct hose routing to prevent kinking. Always replace hose clamps when installing new hoses, and use a coolant pressure tester to verify no leaks before returning to service.
Why are silicone radiator hoses so much more expensive, and are they worth it?
Silicone hoses cost 3-4 times more than standard rubber but offer significant advantages for commercial trucks. They withstand temperatures up to 350F (versus 275F for EPDM), resist degradation from oil and coolant additives, and typically last 5-7 years compared to 2-3 years for rubber hoses. For trucks running extended service intervals, operating in extreme temperatures, or using extended-life coolants, silicone hoses often pay for themselves by reducing downtime and maintenance frequency.
What are the signs that my radiator gaskets need replacement, and can I reuse old ones?
Look for dried coolant residue around tank-to-core joints, slight coolant seepage after overnight parking, or a sweet smell in the engine compartment. Radiator gaskets should never be reused once removed - they compress and take a set that prevents proper resealing. When replacing tubes or performing radiator service, always install new gaskets. For Peterbilt 567/579 models, the upper and lower tank gaskets are different sizes, so ensure you order the complete gasket kit specific to your radiator manufacturer (typically Behr or Modine).
