Fan Relay on 2002 BMW 530i

Where exactly are the fan relays located for the cooling system? The car keeps overheating even after a new radiator, thermostat, and fan clutch. Could it be the fan relay thats causing the problem?

First you must scan the data to see what the issue is with the cooling fan system. Then you can estimate what the repair will be, but first and foremost you need to have the problem properly diagnosed. It could be so many things especially on a car that has about 45 computer systems !!

With A/C on fan speed one is normally activated by the IHKA. Only Via BMW tester equipment can you check the operation of fan speed 2 without running the car hot. Remove and check the water pump These water pumps use a plastic impeller and decay over time, the impeller becomes separate to the main pump shaft, causing over heating at nearly all situations. They are very stubborn to remove, there are 2 threaded holes on the side of the pump, screw in two 10mm bolts evenly and SLOWLY and this should push the pump away from the block. If the pump breaks upon removal, it needs replacing anyway and goodluck, the pump bonds to block like crazy and requires several sharp blows to crack the pump into pieces.
