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.
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.
