Peterbilt 567/579 Radiator Tubes, Gaskets & Hoses

Frequently Asked Questions About Peterbilt 567/579 Radiator Tubes, Gaskets & Hoses

How do I know if a radiator tube, gasket, or hose will fit my Peterbilt 567 or 579?

Fitment can vary based on engine option, model year, and cooling system configuration, so it's important to check the part number and specifications listed on each product page against your truck's build sheet or existing component. If you're unsure, our parts team can help confirm compatibility using your VIN or engine serial number before you order.

What are the signs that my radiator hose or gasket needs to be replaced?

Common warning signs include visible coolant leaks, cracking or soft spots on hoses, coolant residue around gasket seams, low coolant levels without an obvious cause, or the engine running hotter than normal. Catching these issues early can help prevent overheating and more costly repairs down the road.

Are these radiator tubes, gaskets, and hoses made from OEM materials, or are they aftermarket replacements?

Our selection includes both genuine Peterbilt OEM parts and quality aftermarket alternatives. Each product listing specifies whether the part is OEM or aftermarket, along with material details, so you can choose based on your budget and preference for original manufacturer specifications.

What should I check before installing a new radiator hose or gasket?

Before installation, inspect the mating surfaces for corrosion, debris, or old gasket material that needs to be cleaned off, and make sure the replacement part matches the correct diameter, length, and fitting style. It's also a good idea to inspect surrounding clamps, fittings, and hardware, since worn components nearby can affect a new part's seal and performance.

Can a damaged radiator tube or hose cause bigger cooling system problems if not replaced quickly?

Yes. A leaking or failed hose, gasket, or tube can lead to coolant loss, engine overheating, and in some cases serious engine damage if the truck continues to run without adequate coolant flow. Replacing worn components promptly helps protect the engine and keeps your truck reliable on the road.
