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.
