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.
Signs of Failure
- 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

OEM vs Aftermarket — 2003 Acura Rsx Radiator
Recommendation: Quality Aftermarket Acceptable
Radiators are straightforward heat exchangers where quality aftermarket units perform well. The key factors are proper fitment, quality materials (aluminum core, plastic tanks), and adequate cooling capacity. Reputable aftermarket manufacturers produce radiators that meet or exceed OE specifications. OEM radiators are preferred for vehicles with demanding cooling requirements (towing, performance) or complex integrated designs. Used OEM radiators are excellent value if undamaged and not corroded internally.
OEM Advantages
- Exact fit guaranteed
- Proven cooling capacity
- Correct transmission cooler size
- OE quality materials and construction
- Designed for vehicle's specific needs
Aftermarket Advantages
- New unit condition
- Competitive pricing
- Often improved designs
- Upgraded materials available
