Frequently Asked Questions About Peterbilt 352 Radiator Tubes, Gaskets & Hoses
What years and models are these radiator components compatible with?
Our Peterbilt 352 radiator tubes, gaskets, and hoses are designed to fit 1969-1981 Peterbilt 352 models. However, compatibility can vary based on your specific engine configuration (CAT 3406, Cummins NTC, or Detroit Diesel). Always verify your radiator core size and inlet/outlet configurations before ordering. If you're unsure, provide us with your OEM or radiator part number, and we'll help confirm the correct fit.
Are these OEM quality parts or aftermarket replacements?
We carry both OEM-specification and high-quality aftermarket options. Our aftermarket radiator hoses are made from EPDM rubber rated for temperatures up to 257?F and meet or exceed SAE J20 R4 specifications. Gaskets feature multi-layer construction with steel cores for durability. All products are tested for proper fit and seal integrity. Each product listing clearly indicates whether it's OEM or aftermarket.
How difficult is it to replace these components myself?
Replacing radiator hoses and gaskets on a Peterbilt 352 is considered a moderate DIY job that typically takes 2-4 hours. You'll need basic hand tools, a drain pan, and fresh coolant. The main challenges include accessing lower radiator connections and properly torquing fittings to prevent leaks. Upper hoses are generally easier to access. We recommend having a service manual handy and always replacing hose clamps when installing new hoses.
What's included in a complete radiator hose kit?
Our complete kits typically include upper and lower radiator hoses, bypass hoses, heater hoses, and all necessary clamps. Some kits also include thermostats and gaskets. Each product page specifies exactly what's included. Individual components are also available if you only need to replace specific hoses. Note that radiator-to-engine oil cooler lines are usually sold separately.
How can I prevent premature hose failure?
The most common causes of early hose failure on Peterbilt 352s are coolant contamination, over-tightened clamps, and heat damage from exhaust components. Use only recommended coolant types, replace coolant every 2-3 years, and ensure hoses have adequate clearance from hot surfaces. When installing, avoid twisting hoses and position clamps at least 1/4 inch from hose ends. Regular visual inspections for soft spots, cracks, or swelling can catch problems before roadside failures occur.
