Description
ATRO RM75-63861 is a polyurethane radiator mount for Peterbilt conventional trucks, replacing Peterbilt 07-05861. The radiator mount supports the radiator and charge-air cooler in the front clip and isolates the cooling stack from frame vibration. ATRO’s high-temperature polyurethane is engineered to outlast OE rubber by three to five times and resists oil, grease, hydraulic fluid, diesel fuel, ozone, and road salt. Made in the USA and backed by ATRO’s 3-year manufacturer warranty.
Signs You Need a New Radiator Mount
- Radiator or charge-air cooler shifts or rocks in the front clip
- Visible flattening, cracking, or missing mount material
- Coolant or charge-air-cooler hose chafing against adjacent components
- Stress cracks at the radiator-tank or CAC inlet/outlet flanges
