Question about Subaru Loyale
first unplug the cooling fan at its plug and supply 12v to the fan if it doesnt run then replace if it does run follow the power wire to the thermal water switch usualy located at the bottom of the radiator.Use test light/probe to check that you have power into the switch and when engine is hot you should have power both in and out of the switch.if not replace thermal water switch.If that is working you will need to find out why you have no power to the switch.Check that your fuse and relay is working correctly.Sometimes just pulling out the relay and putting back in will make it work due to poor contact.Also try swapping relays with others in the same box near battery to identify if relay is faulty

As long as the fan eventually shuts off this isn't a problem,the fan will continue to run for a bit after the car is turned off,once it reaches a set temprature it will turn off.

The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps

The main reason for the over heating of the audi tt is to do with the water pump. The propeller within the first type of water pumps is made of plastic. This was to prevent corrosion, however was never designed to last longer than 5 years. What you need to do is purchase the new style water pump. These new style water pumps have been designed with a metallic propellor which should resolve the overheating. Let us know how you get on.

The fan that draws cool air across the radiator can be driven by either a belt or electricity. Rotating fans can be dangerous. Some are controlled by an automatic switch and can start unexpectedly. When working on electric fans, keep in mind that electric cooling fans should be disconnected when working around them.
When replacing a radiator fan motor, always refer to the vehicle's service manual. The following is a general guide for cooling fan replacement.
