Frequently Asked Questions About Peterbilt 587 Radiator Tubes, Gaskets & Hoses

What years do these radiator components fit, and are they compatible with both standard and heavy-duty cooling systems?

Our Peterbilt 587 radiator tubes, gaskets, and hoses are designed for model years 2008-2017. Most components work with both standard and heavy-duty cooling packages, but it's important to verify your specific radiator configuration. Check your VIN or existing part numbers to ensure compatibility, especially if you have the optional 1,400 square inch radiator versus the standard 1,200 square inch model.

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

OEM hoses use EPDM rubber compounds rated for temperatures up to 257?F and typically last 4-6 years. Quality aftermarket options from brands like Gates and Dayco offer similar specifications at 30-40% less cost. The main differences are warranty length (OEM offers 2 years, aftermarket usually 1 year) and pre-formed versus universal fit designs. For daily drivers, aftermarket hoses provide excellent value. For extreme conditions or extended warranties, OEM may be worth the extra investment.

Do I need special tools to replace radiator hoses and gaskets, and how difficult is the installation?

Basic hand tools are sufficient for most hose replacements - you'll need pliers for clamps, a flat-head screwdriver, and a drain pan. Gasket replacement requires removing the radiator, which adds complexity and typically takes 3-4 hours. The upper radiator hose is accessible and takes about 30 minutes to replace. Lower hoses require working underneath and may need coolant system draining. Always replace hose clamps when changing hoses, and use a torque wrench for radiator mounting bolts (18-22 ft-lbs).

How do I identify which radiator tube or hose I need when there are multiple options listed?

Start by locating the part number on your existing component - it's usually printed or molded on the hose. For tubes, measure the diameter (typically 1.75" or 2" ID) and length. Note whether you have aluminum or plastic tank connections. Engine options matter too - ISX15 engines use different configurations than Cummins ISX12. When in doubt, provide your VIN and our team can verify the exact match. Photos of your current setup help tremendously in identifying the correct replacement.

What are the signs that gaskets need replacement, and can I reuse old gaskets during radiator service?

Never reuse radiator gaskets - they compress during initial installation and won't seal properly if reinstalled. Signs of gasket failure include coolant residue around tank seams, slow coolant loss without visible leaks, and white or green crusty deposits near gasket areas. During any radiator removal, plan to replace all gaskets. Our gasket sets include tank-to-core gaskets, inlet/outlet gaskets, and mounting gaskets. Using new gaskets prevents comeback leaks and typically costs under $40 for a complete set.
