Frequently Asked Questions About Peterbilt 387 Radiator Tubes, Gaskets & Hoses

What components are included in this category?

This category covers the radiator tubes, sealing gaskets, and coolant hoses used in the cooling system of the Peterbilt 387. These parts work together to circulate coolant between the radiator, engine, and related components, and to maintain a leak-free seal at connection points.

How do I know if a radiator tube, gasket, or hose will fit my Peterbilt 387?

Fitment can vary depending on the model year, engine option, and radiator configuration installed on your truck. Always compare the part number listed on the product page to your truck's build sheet or the part currently installed, and check with our parts specialists if you are unsure before ordering.

What are the signs that a radiator tube, gasket, or hose needs to be replaced?

Common warning signs include visible coolant leaks, low coolant levels, wet or corroded spots around hose connections, cracked or brittle hose material, and overheating. Gaskets that have hardened or lost their seal can also allow coolant to seep out around mounting points.

What material are these parts made from, and does it affect durability?

Radiator hoses are typically made from reinforced rubber designed to withstand heat and pressure cycling, while gaskets are often made from rubber or composite materials suited for sealing against coolant and vibration. Tubes are generally aluminum or a similar corrosion-resistant metal. Choosing quality materials helps reduce the risk of premature cracking, hardening, or leaks.

Can I install a replacement radiator tube, gasket, or hose myself?

Many truck owners and shops handle this type of replacement, but it does require draining the cooling system, removing the old component, and properly seating the new part to avoid leaks or air pockets. If you are not comfortable working around a pressurized cooling system, it's best to have the installation done by a qualified technician.
