Bmw E39 Aux Fan Relay

E39 auxiliary fan wiring diagram wiring diagram is a simplified up to standard pictorial representation of an electrical circuit.

Bmw e39 aux fan relay.

Switches motors relays fuses wiring for bmw 5 series e39 1996 2003. So i am thinking that maybe all that needs to be replaced is the auxiliary fan switch aka temperature sensor part 13 62 1 433 077 which controls the operation of the auxiliary fan. Fuse box in passenger compartment bmw e39. For the bmw e39 1996 1997 1998 1999 2000 2001 2002 2003 model year.

Tools needed was a 1 4 ratchet 8mm 10mm 13mm sockets. It shows the components of the circuit as simplified shapes and the aptitude and signal friends together with the devices. A unlike the older bmw models most models up through 1999 the auxiliary cooling fan on the later models is not just controlled by a coolant temperature. On all bmw models up through the late 90s the auxiliary or main fan is controlled by one or two thermostatic switches that are mounted into the radiator side or bottom tanks.

I have 2001 530i bmw i plan to convert my clutch fan to elect fan the vendor told me that the elec fan will come in as push type but i can change it to pull type which one is better i also plan to leave the aux fan located in front of condenser because the fan is still working when a c is on what do you think. Your problem is either the temperature sensor or the fan relay. The temperature sensor screws into the back of the radiator on the reservoir side.
