Frequently Asked Questions About Peterbilt 362 Radiator Tubes, Gaskets & Hoses

What years and models are these radiator components compatible with?

Our Peterbilt 362 radiator tubes, gaskets, and hoses are designed to fit 362 models from 1980 through 1986. However, compatibility can vary based on your specific engine configuration (CAT 3406, Cummins Big Cam, or Detroit Series 60). Always verify your radiator core size and inlet/outlet positions before ordering, as some 362s came with different radiator configurations depending on the original engine option.

Are these OEM quality parts or aftermarket replacements?

We carry both OEM-spec and high-quality aftermarket options. Our aftermarket radiator hoses are made from EPDM rubber with reinforced fabric layers that meet or exceed OEM specifications for temperature resistance (-40?F to 257?F) and pressure ratings (up to 80 PSI). Gaskets are typically aftermarket but manufactured to exact OEM dimensions using materials like reinforced rubber or silicone that often outlast original equipment.

How difficult is it to replace radiator hoses and gaskets on a 362?

Replacing upper and lower radiator hoses typically takes 1-2 hours and requires basic hand tools. The main challenges include accessing clamps behind the fan shroud and dealing with stuck hoses on older trucks. For gasket replacement, expect 3-4 hours as you'll need to drain the coolant, remove the radiator tanks, and clean mating surfaces thoroughly. Having a second person helps when positioning the radiator during reinstallation.

What's the difference between molded and universal flex hoses?

Molded hoses are pre-formed to match the exact bends and angles of your Peterbilt 362's cooling system, ensuring proper fit without kinking. Universal flex hoses can be bent to shape but may require careful routing to avoid sharp bends that restrict flow. We recommend molded hoses for the upper radiator connection due to the specific angle required, while flex hoses work well for lower connections with straight runs.

How often should I replace these cooling system components?

Radiator hoses should be inspected every 50,000 miles and typically last 4-5 years under normal conditions. Look for soft spots, cracks, or swelling near clamp areas. Gaskets generally last longer but should be replaced whenever you service the radiator or notice coolant seepage. If your 362 operates in extreme temperatures or hauls heavy loads regularly, consider replacing hoses every 3 years as preventive maintenance to avoid roadside failures.
