Peterbilt 567/579 Radiators

Frequently Asked Questions About Peterbilt 567/579 Radiators

Will this radiator fit my Peterbilt 567 or 579 without modifications?

Radiators listed in this category are designed to match the OEM specifications for the Peterbilt 567 and 579 models, including core dimensions, tank configuration, and mounting points. However, fitment can vary based on engine type, model year, and whether your truck has additional cooling components like charge air coolers. Always check the listed specifications against your truck's VIN or existing radiator before ordering to confirm an exact match.

What material are these radiators made of, and how does it affect performance?

Most replacement radiators in this category feature aluminum cores with either plastic or aluminum tanks. Aluminum cores are valued for efficient heat dissipation and resistance to corrosion, while the tank material can influence durability under pressure and heat cycling. If you're running heavy loads or frequent long hauls, an all-aluminum radiator may offer added durability compared to a plastic-tank option.

Can I install this radiator myself, or should I have a professional do it?

While experienced DIYers with the right tools can replace a radiator, it's a job that involves draining coolant, disconnecting hoses, and sometimes removing surrounding components like the fan shroud or grille. Because proper installation affects engine cooling and long-term reliability, many truck owners choose to have this job done by a qualified diesel mechanic, especially if it's their first time replacing a heavy-duty radiator.

How do I know if I need a new radiator versus having mine repaired?

Common signs that point to a full replacement rather than a repair include visible cracks in the tank, extensive core damage, persistent leaks after previous repairs, or reduced cooling efficiency that leads to overheating. Minor leaks or damaged fittings can sometimes be repaired, but if your radiator is old or has multiple issues, replacing it is often more cost-effective in the long run.

Do these radiators come with a warranty?

Warranty coverage varies by manufacturer and specific product, so it's important to check the warranty details listed on each individual product page. In general, most radiators carry a manufacturer's warranty against defects in materials or workmanship, but coverage terms and length can differ between brands.
