Signs to investigate
- Coolant leaking from the radiator
- Repeated overheating
- Damaged or corroded radiator fins and tanks
- Coolant residue or a sweet smell at the front of the car

- Radiator size and construction
- Front-end access and component removal
- Coolant type and bleeding procedure
- Hoses, cap, thermostat or fan repairs
Questions to ask the workshop
- Where was the leak confirmed?
- What radiator brand and warranty are included?
- Will the system be pressure-tested after repair?
- Has the cause and any overheating damage been checked?
Understand the repair scope
The leak or restriction is confirmed before parts are removed, with attention to hoses, tanks, cap, fans and nearby components that can mimic a radiator fault.
Coolant is recovered, obstructing trim or cooling fans are removed, and the radiator is replaced without stressing air-conditioning lines or automatic-transmission cooler fittings.
Correct coolant is added, trapped air is bled using the vehicle-specific procedure, and the system is pressure-tested and brought to operating temperature to confirm fan and thermostat operation.
Checks that should support the diagnosis
A symptom alone does not prove a part has failed. Before authorising work, ask what inspection or test led to the recommendation.
- Pressure-test the cooling system when cold
- Inspect radiator tanks, core, cap, hoses and seams for residue
- Check fan operation and airflow through the core
- Assess for combustion leakage or other damage if the engine overheated
What a comparable quote normally includes
Compare like with like. A lower quote may simply cover less of the job.
- Replacement radiator
- Specified coolant and system refill
- Removal and refitting of fans or trim needed for access
- Pressure, leak and operating-temperature check
Possible extra work
These items are not automatically required, but they can change the bill when inspection shows they are needed.
- Radiator hoses, cap or clamps
- Automatic-transmission cooler lines or fittings
- Thermostat, cooling fan or water-pump repair
- Further testing for engine damage after severe overheating

Does the estimate include parts and labour?
Yes. Most jobs show modelled parts, labour and rates separately. Published supplied-and-fitted examples include installation in the advertised price. They do not provide a separate parts/labour breakdown; confirm tax, fees and fitment with the supplier.
What should a radiator quote explain?
A useful written quote should identify the repair scope, the main parts being supplied, the expected labour and any likely additional work. For this job, common inclusions are replacement radiator, specified coolant and system refill, removal and refitting of fans or trim needed for access.
