Radiator Repair in London, Ontario
Get dependable radiator repair in London from independent, family-owned auto repair shops who understand Preventing coolant system failure in extreme winter cold.
Why Radiator Repair Matters in London
London drivers experience Sustained highway driving to Toronto stresses cooling system; winter stress on heater circulation. Combined with Coolant freezing risk below -30°C if concentration is improper; road salt corrodes radiators, this places additional stress on your vehicle's radiator, coolant hoses, and water pump.
Early inspection helps ensure small radiator repair issues don't develop into larger repairs.
Common Signs You May Need Radiator Repair
Cooling system issues can lead to engine damage. Watch for:
- Engine temperature running high
- Coolant leaks under the vehicle
- Low coolant warning light
- Sweet smell from the engine bay
- Visible rust or damage on radiator

FAQs About Radiator Repair in London
Use 50/50 ethylene glycol antifreeze with distilled water for London winters. This provides freeze protection to -34°C, matching London's coldest extremes. Check concentration with a hydrometer; improper ratios freeze at -10°C or overheat at high temps. Flush and refill annually in fall to maintain proper concentration.
Road salt spray corrodes aluminum radiator fins and copper tubes, reducing cooling efficiency. Signs of failure include overheating, sweet smell (glycol leak), puddles under your car, or white crusty buildup on radiator. Radiator damage worsens quickly in London; corrosion spreads within months if unaddressed.
Old coolant loses corrosion inhibitors and antifreeze effectiveness. Flushing removes rust particles that clog heater cores and reduce heat output. Fresh coolant with proper glycol concentration protects against freeze-ups, overheating, and corrosion. An annual flush before November costs $100-$150 and prevents $500+ radiator repairs.
