Peterbilt 367 Radiator Tubes, Gaskets & Hoses

Frequently Asked Questions About Peterbilt 367 Radiator Tubes, Gaskets & Hoses

What is the difference between radiator tubes, gaskets, and hoses, and which one do I need?

Radiator tubes are the internal channels that carry coolant through the radiator core, gaskets seal connection points between the radiator and other cooling system components to prevent leaks, and hoses transfer coolant between the radiator, engine, and other parts of the cooling system. If you are dealing with a leak, overheating, or visible cracking, inspect the specific component showing damage so you replace only what is needed rather than the entire assembly.

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

Common signs include visible coolant leaks or puddles under the truck, low coolant levels without an obvious cause, engine overheating, soft or cracked hoses, and white residue or corrosion around gasket seams. If you notice any of these symptoms, inspect the cooling system closely, as small leaks can worsen quickly and lead to engine damage if left unaddressed.

Will these parts fit my Peterbilt 367 regardless of engine or model year?

Radiator components can vary based on engine type, radiator design, and production year, so it is important to confirm fitment details listed on each product page before purchasing. If you are unsure whether a part matches your specific configuration, check your existing component for reference numbers or reach out to our team with your truck's details so we can help verify compatibility.

What material are these radiator tubes, gaskets, and hoses made from?

Radiator tubes are typically made from aluminum or brass for efficient heat transfer, gaskets are commonly constructed from rubber or composite materials designed to withstand heat and pressure, and hoses are generally made from reinforced rubber to handle coolant flow and engine vibration. Material specifications are listed on individual product pages, so check there for details specific to the part you are considering.

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

Many drivers and shop technicians replace hoses and gaskets themselves since the process generally involves draining coolant, removing the old part, and securing the new one with proper clamps or fasteners. However, radiator tube repairs or replacements can be more involved depending on whether the core itself is affected, so if you are not comfortable working on the cooling system or if the issue involves the radiator core, it is a good idea to have a qualified technician handle the job to avoid further damage or improper sealing.
