Radiator buying guide

Why replace this part?

The radiator dissipates engine heat by transferring it from coolant to the air. A leaking or clogged radiator causes engine overheating, which can result in catastrophic engine damage including warped heads and blown gaskets.

Signs you need a replacement

  • Coolant leaks or puddles under the car
  • engine overheating
  • discoloured or rusty coolant
  • visible corrosion or damage to radiator fins
  • steam from under the bonnet

When to replace

Typically lasts 8–10 years. Replace when leaks develop or internal blockages cause overheating. Flush cooling system every 5 years.

Installation difficulty:Moderate — requires basic tools and mechanical knowledge
