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

Will these radiator components fit my specific year model Peterbilt 367?

Most radiator tubes, gaskets, and hoses for the Peterbilt 367 are designed to fit models from 2007 to present. However, there were minor changes in 2011 and 2015 that affect some components. Always verify compatibility by checking your truck's VIN and engine type (Cummins ISX, PACCAR MX, or Cat C15) before ordering. If you're unsure, our parts specialists can confirm fitment with your specific truck details.

What's the difference between OEM and aftermarket radiator hoses, and which should I choose?

OEM hoses typically use EPDM rubber rated for -40?F to 257?F and come with factory-style constant tension clamps. Quality aftermarket options like Gates or Continental use similar materials but may cost 30-40% less. The main differences are warranty length (OEM usually 2 years vs. 1 year aftermarket) and exact bend formations. For daily drivers, quality aftermarket hoses perform equally well. Choose OEM if you need exact factory routing or have warranty requirements.

Do I need special tools to replace radiator tubes and hoses on my 367?

Basic replacement requires standard hand tools including various socket sizes (typically 10mm-19mm), hose pick tools, and drain pans. However, accessing upper radiator connections often requires removing the charge air cooler, which needs torque wrenches for proper reassembly (specs: 35-45 ft-lbs for most connections). Some 2015+ models with emissions equipment may require additional clearance work. Budget 3-4 hours for complete hose replacement if doing it yourself.

How can I tell if my radiator gaskets are failing before they completely blow out?

Early warning signs include dried coolant residue (white or green crusty buildup) around gasket seams, slight coolant smell in the engine compartment, or minor coolant level drops without visible leaks. Check the tank-to-core gaskets and inlet/outlet flanges during pre-trip inspections. Gaskets typically last 5-7 years but can fail earlier in extreme temperature regions. Replace gaskets whenever you service major cooling components to prevent roadside failures.

What's included in a complete cooling system hose kit for the 367?

A comprehensive kit should include upper and lower radiator hoses, heater hoses (supply and return), bypass hoses, and all necessary clamps. Some kits also include thermoststat housing gaskets and radiator cap. Be aware that charge air cooler hoses and oil cooler lines are typically sold separately. Verify your engine model as Cummins ISX kits differ from PACCAR MX kits in hose routing and connection sizes.
