Your radiator tubes, gaskets, Peterbilt fan shroudsand hoses essentially form the arteries of your PB 379's cooling system. They carry coolant to and from the radiator, seal key connection points, and help regulate engine temperature by ensuring consistent circulation. If even one component fails, you could be looking at overheating, downtime, or even engine damage. - Peterbilt Upper Radiator Hose & Coolant Hoses: Flexible Peterbilt coolant hoses carry coolant between the engine and radiator. Over time, these can crack, swell, or leak. Our replacement options are built from reinforced rubber or high-temp silicone for long life and a tight seal. - Radiator Tubes: Our upper coolant tubes are precision-engineered to direct hot coolant from the engine to the radiator. Made from stainless steel or reinforced materials, they resist pressure, corrosion, and vibration ideal for tough road conditions. - Radiator Gaskets: We carry gaskets for the radiator core and tank junctions, built to handle pressure and prevent internal leaks. Proper sealing ensures your cooling system maintains pressure and performs at peak efficiency. - Hose Clamps: Our torque-specific coolant hose clamps offer even sealing pressure across connections minimizing the chance of leaks or hose blowouts. A must-have for reliable cooling system performance. - Radiator Mounts & Support Bushings: Secure your radiator with high-quality mounts and support rod bushings that absorb vibration and allow for thermal expansion helping prevent stress cracks and radiator failure. - Coolant Level Sensor Kits: Add a sensor that warns you of low coolant before your temp gauge spikes. Early detection means you can avoid overheating and expensive repairs. There are several benefits to replacing old or damaged radiator components for your classic truck: - Prevents Overheating: Keep coolant flowing freely and your engine within safe operating temps. - Protects Your Engine: Avoid thermal stress, overheating, and costly damage. - Reduces Downtime: Minimize the risk of roadside breakdowns or coolant loss. - Improves Fuel Efficiency: A properly cooled engine burns fuel more efficiently. - Extends Engine Life: Keep temps stable and parts protected under all load conditions. - Supports Other Cooling Components: Maintain proper pressure to protect your water pump, thermostat, and fan clutch. When should you replace these cooling parts. If you're seeing signs like swelling hoses, coolant leaks, steam from under the hood, or rising engine temps it's time to inspect and replace your radiator components. don't wait for a small leak to become a big problem.

Frequently Asked Questions About Peterbilt 379 Radiator Tubes, Gaskets & Hoses

What is the difference between a radiator tube, gasket, and hose in this category?

Radiator tubes are the internal metal or composite passages that carry coolant through the radiator core, gaskets are the seals that prevent leaks at connection points such as the tank-to-core joint, and hoses are the flexible lines that route coolant between the radiator, engine, and other cooling system components. Together these parts work to keep the cooling system sealed and functioning properly, and each is prone to wear or damage over time from heat, vibration, and age.

How do I know if my radiator tube, gasket, or hose needs to be replaced?

Common signs include visible coolant leaks or residue around the radiator or hose connections, low coolant levels that require frequent top-offs, overheating, cracked or brittle hoses, or corrosion and pitting on metal tubes. If you notice any of these symptoms, it is a good idea to inspect the specific component closely, as a failed gasket or hose can lead to bigger cooling system problems if left unaddressed.

Will these parts fit my specific Peterbilt 379 model year and engine configuration?

Radiator components can vary based on the model year, radiator core design, and engine option installed in your truck, so it is important to check the listed specifications and part numbers against your truck's existing components before ordering. If you are unsure, comparing measurements or your radiator's part number to the product listing is the most reliable way to confirm a proper fit.

Can I install a replacement radiator tube, gasket, or hose myself, or should I have a professional do it?

Many hoses and gaskets can be replaced by someone comfortable with basic mechanical work and the proper tools, such as hose clamps and a way to safely drain and refill coolant. Radiator tube repairs or replacements, however, often involve more disassembly and may require soldering, sealing, or core work, so those jobs are frequently better suited for a shop or experienced technician to ensure a leak-free result.

What material or quality differences should I look for when choosing a replacement part?

Radiator tubes are typically available in materials like aluminum or copper/brass, each with different durability and heat transfer characteristics, while gaskets are commonly made from rubber or composite materials designed to withstand engine heat and coolant exposure. Hoses vary in wall thickness and reinforcement, which affects their resistance to pressure and heat cycling. Choosing a part that matches or exceeds your original component's specifications will help ensure a proper seal and long-term reliability.
