Engine Cooling System Repairs FAQs
Is engine cooling the same as air-conditioning?
No. Engine cooling controls engine temperature. Air-conditioning cools the cabin and has its own dedicated service page.
Does overheating always mean the radiator needs replacing?
No. Leaks, thermostat, fan, water-pump or other faults may be involved. Assessment is needed before selecting a repair.
Should I keep driving with an overheating warning?
Stop safely and follow the vehicle handbook. Do not open the cooling system while hot. Contact the workshop to discuss the symptoms and suitable transport.
Can a coolant leak be assessed?
Yes. Describe the leak, warning messages and vehicle details. The workshop will confirm appropriate checks and availability; any further engine investigation requires an agreed scope.
