What cooling system service is
Cooling system service keeps the engine at the temperature it was designed to run at. The system is checked for leaks and flow, coolant is replaced when required, and the components that regulate temperature are inspected.
Why it matters
Overheating is one of the quickest ways to turn a moderate repair into a major one — a warped head or a failed gasket. Modern engines run hotter than older ones, so correcting a cooling fault early protects the whole engine.
Recognise any of these?
Common reasons customers ask us to look at this system. These are general signs — they do not confirm a fault, and they are not a diagnosis of your car. Only an inspection can establish what is actually happening.
Common reasons customers ask for this service
- The temperature gauge climbing above its normal position
- A coolant warning light, or the reservoir needing frequent top-ups
- Green, pink or orange puddles under the front of the car
- A sweet smell, or steam from under the bonnet
- The heater blowing cold, or the radiator fan not switching on
- Rusty or discoloured coolant in the reservoir
What happens at the workshop
The exact steps depend on what the inspection finds. This is the general process we follow for this service.
What the service involves
- A pressure test to locate leaks in the system
- Radiator, hoses, thermostat, water pump, cap and cooling fans checked
- Belts and the fan operation inspected
- A flush and refill with the correct coolant for the vehicle
- A post-service temperature check to confirm the fix
We do not quote or carry out work on this service without inspecting the vehicle first, and any repair is agreed with you before it begins.
