How long does a radiator replacement take?
Most radiator replacements take 2-6 hours depending on vehicle complexity. Simple cars might be completed in 2-3 hours, while luxury or difficult-access vehicles can take up to 6 hours including diagnosis and testing.
Can I drive with a damaged radiator?
No, driving with a damaged radiator risks severe engine damage from overheating. If your radiator is leaking or not cooling properly, stop driving immediately and arrange for professional repair to avoid costly engine rebuild.
What's included in radiator replacement cost?
Standard replacement includes the new radiator, coolant refill, labour, and basic warranty. Additional costs may apply for thermostat replacement, cooling system flush, or if other components need repair during the process.
Should I choose OEM or aftermarket radiator?
OEM radiators offer guaranteed fit and performance but cost more. Quality aftermarket radiators can be 20-40% cheaper while still providing reliable service. For newer or luxury cars, OEM is often recommended for warranty purposes.
How often should radiators be replaced?
Radiators typically last 8-15 years or 150,000-300,000 kilometres with proper maintenance. Regular coolant changes, system flushes, and keeping the radiator clean can significantly extend its lifespan.
What warranty should I expect?
Reputable mechanics typically offer 12-24 months warranty on radiator replacement. Premium services may include longer warranties. Always confirm warranty terms cover both parts and labour before proceeding with the replacement.
