Peterbilt 579 Radiators — Replacement Parts & Pricing

Radiator lifespan varies depending on duty cycle, maintenance schedule, and operating conditions, so there's no single fixed number of years or miles. Instead, watch for common warning signs that a radiator is nearing the end of its service life, including engine overheating, visible coolant leaks around the radiator or tanks, discolored or contaminated coolant, external corrosion or physical damage to the core, and unexplained coolant loss. Choosing OEM-equivalent quality replacement parts, like those Radiator Supply House offers under the ICEBOX brand, helps ensure the new radiator matches original manufacturer specifications for fit, performance, and durability.

Replacing a radiator in a Peterbilt truck typically takes 3 to 6 hours for an experienced heavy-duty truck technician. The time varies based on the specific model, cab configuration, and whether additional components such as the charge air cooler or oil cooler are being replaced simultaneously. Having all parts on hand beforehand minimizes downtime significantly.
