Kenworth T800 Radiator Tubes, Gaskets & Hoses

Frequently Asked Questions About Kenworth T800 Radiator Tubes, Gaskets & Hoses

What components are included in this category?

This category covers the cooling system components that connect and seal your Kenworth T800 radiator, including upper and lower radiator tubes, radiator hoses, and the gaskets or seals used at tube and hose connection points. These parts work together to keep coolant flowing properly between the radiator, engine, and related cooling system components.

How do I know if a radiator tube, hose, or gasket is compatible with my T800?

Fit can vary depending on your truck's model year, engine option, and radiator configuration, since Kenworth updated the T800 platform over multiple production years. Always check the part number against your truck's specifications or your old part before ordering, and reach out to our parts team if you are unsure which version matches your setup.

What signs indicate a radiator tube, hose, or gasket needs to be replaced?

Common warning signs include visible coolant leaks around hose connections or tube joints, cracking or soft spots in rubber hoses, white residue or crusty buildup near gaskets, and unexplained coolant level drops. Overheating or fluctuating engine temperature gauges can also point to a failing tube, hose, or gasket.

Are these parts made from OEM materials, or are aftermarket options available?

We carry a mix of OEM and quality aftermarket replacement parts for the T800 cooling system. Aftermarket tubes, hoses, and gaskets are typically built to match OEM dimensions and performance, giving you a reliable option that can also be more budget friendly. Product listings will note whether an item is OEM or aftermarket so you can choose what works best for your truck and budget.

What should I keep in mind when installing a new radiator tube, hose, or gasket?

Before installation, make sure the engine has cooled completely and the coolant system is fully drained to avoid burns or spills. Inspect mounting surfaces and connection points for corrosion or debris, and replace any worn clamps or fasteners along with the new part. Tighten connections to proper specifications, since overtightening can damage gaskets or hoses while undertightening can lead to leaks, then check for leaks after refilling and running the engine.
