The electric cooling fans use a radiator mounted thermo switch and a second thermo switch mounted in the coolant manifold to control fan motor operation. The fans operate at low speed when engine coolant temperature is 183-192°F and at high speed when coolant temperature is 194-203°F. The A/C system will also switch on various fan speeds dependent on coolant temperature and refrigerant pressure.

DRIVELINE, U-JOINT & CV AXLES REPLACEMENT PROCEDURES FOR 2004 Volkswagen Golf AUTOMOBILES
CV AXLE SHAFT, Replace
Vehicle: 2004 Volkswagen Golf 1.9 L4 DIESEL
Wheel bearing must not be burdened while 12 point nut is loose.
If wheel bearing is burdened by weight of vehicle, wheel bearing will be pre-damaged. This will diminish wheel bearing service life.
If it should be necessary to move a vehicle whose drive axle has been removed, before doing so install an outer joint in place of drive axle and tighten it to 11 ft. lbs., or else wheel bearing will be damaged.
The wheel hub/axle shaft on model "Golf GTI 132 kW" and R32 is secured with a hex bolt instead of a 12-point nut. The spline of outer joint is slightly shorter than previous...
