About the GMC Sierra-2500-Extended-Cab Radiator (RAD)

The radiator is the primary heat exchanger in your vehicle's cooling system, responsible for dissipating engine heat into the atmosphere. Hot coolant from the engine flows through the radiator's tubes while air passes over the fins, transferring heat away. A failed or leaking radiator leads to engine overheating, which can cause catastrophic engine damage. The Radiator (also known as RAD) is a critical component for your GMC Sierra-2500-Extended-Cab.

Signs of Failure

Know when your Sierra-2500-Extended-Cab radiator needs replacement:

  • Engine overheating
  • Coolant leaks under the vehicle
  • Low coolant level
  • Discolored or rusty coolant
  • Steam coming from under the hood
  • Temperature gauge running hot
  • Sweet antifreeze smell
  • Visible damage or corrosion on radiator

Replacement Info

Radiator replacement is a moderate DIY job. The process involves: draining the cooling system, disconnecting upper and lower hoses, disconnecting transmission cooler lines (if equipped), removing the cooling fan assembly or shroud, unbolting the radiator mounting brackets, and lifting out the old radiator. Installation is the reverse, followed by refilling with fresh coolant and bleeding air from the system. Most replacements take 2-3 hours. Ensure you properly dispose of old coolant and use the correct coolant type for your vehicle.

Time: 2-4 hours
Difficulty: Moderate DIY
