Replacing the Engine Cooling Radiator
Model: BMW Serie 3
E46
- Years 1998-2006
Remove the air filter and the intake duct protected by the cover. Remove the two side screws from the fan support, disconnect the electrical wiring connector, and using the two special wrenches, loosen the retaining nut to allow for its removal. Position a drain pan under the radiator to collect the coolant. Unscrew the hose clamps on the water inlet to the radiator and remove it. Also disconnect all return hoses. Unclip the retaining springs at the bottom of the expansion tank and remove it from its housing. Remove the pump by disconnecting the electrical wiring connector and unscrewing the two screws. Unscrew the radiator retaining screws and remove it by pulling it upward. Clean the radiator compartment of dirt. Install the new radiator, the expansion tank, the pump, and reconnect all hoses. Reassemble the fan and the air filter. Refill with the appropriate coolant. Start the engine, open the air bleed valve until coolant flows out to eliminate any air bubbles, and check for any leaks.

Oil Change on X City 250
Position an oil collection tray under the oil drain. Open the oil filler cap and proceed to unscrew the drain plug as specified in the video. Once all the oil has drained, you can re-screw the drain plug and tighten it properly. From the right side of the engine, you can refill the new oil of the type recommended by the manufacturer, ensuring to respect the maximum level (check it using the dipstick located in the cap). Once the refilling operation is complete, close the plastic cap, tightening it properly. by ScegliAuto More videos
