  • Most aftermarket coolant reservoir tanks omit the sensor or use non-pressurized caps—leading to false warnings or leaks. Ours includes both, matching your truck’s original design exactly.
  • Towing heavy loads through desert heat? Your 2011–2016 Silverado or Sierra HD demands a coolant reservoir tank that won’t crack under thermal stress or vibration—engineered for real-world duty cycles.
  • Specs: Compatible with Chevy Silverado/GMC Sierra 2500HD/3500HD (2011–2016, 6.6L V8); Replaces OE #603-008, 22957038, 23106015; Includes 20 PSI spring-loaded cap and integrated level sensor.
  • Made from reinforced, heat-resistant plastic with dual mounting points—this pressurized coolant reservoir tank resists warping, cracking, and coolant loss even during extended high-load operation.
  • Backed by PRORONRA’s support team—contact us directly if you have fitment or installation questions. We’re here to help ensure your coolant reservoir tank performs as designed.
