Have you listened under the bonnet to see where exactly the noise comes from and if so is it from the radiator area?
Ok..well the statement as far as the fan cooling the turbo intercooler at cold is false - the intercooler doesnt have fan specifically for that..the intercooler is cooled by the forward motion of the car and the air passes through the intercooler matrix which in turn cools the air passing through inside the intercooler itself..the intercooler is quite small its about a quarter of the size than the main cooling radiator itself and only has an air inlet and outlet tube....I suspect if ther noise is from the front then its likely the main fan coming on at start up..could be any manner of things that needs to be checked..ideally normally if the fan continues or stays on even at cold would suggest an issue with the coolant temp sensor/fan control unit..normally the best place to start ideally is the main coolant temp sensor the ecu uses to detect the coolant temp at cold aswell as hot for starting..the temp sensor normally green in colour the body is or should be part of the thermostat housing..i do hope this helps
Hi..sorry for the delay had internet problems.yesterday
No,not unless it actually leaking coolant or is blocked to allow the engine to overheat..the radiator is only there to allow hot coolant to flow through it or into it - as the forward motion of the car and the air passes thorough the radiator it cools the coolant to certain degree and the coolant passes out back into the engine and is an ongoing cycle..the fan is only there to aid cooling or if the cars sitting stationary for long extented period to keep the coolant temp down..it can also serve as purpose as far as the air conditioning....
