Question about BMW 525
To remove the water pump you will need to remove the shroud.
the shroud is held on with 2 plastic rivets on both sides the upper part of the shroud, they clip into the radiator. Just pry the center of the rivet outwards, and pop the rivet out. The shroud will slide up about 4-5 inches, this is usually enough room to access the waterpump nuts, so it is not needed to fully remove the shroud. To fully remove, youll need to remove the expansion tank, and the sensor that slides into the shroud on the driver side. Then feed the expansion tank hoses out through the holes in the shroud. Be careful not to break the small vent hose ends on the radiator, and expansion tank.
expansion tank is on passenger side with two lines running out of the bottom of it. The fan blade have to be removed to access water pump.
it's threaded onto the end of the water pump.
You will need a 32mm wrench, and something to hold the pulley, they make special tools for this, but in a pinch you can use a long flat screwdriver to hold the w/p pulley in between the bolt heads. And a large channel locks. The thread is reverse, turn clockwise to loosen. The hoses are secured to the tank using spring clips since they have plastic ends, you need to pull the clip out for each one, and wiggle them loose and pull off. They get pretty stuck sometimes.
The item on the bottom is the auxillary water pump, it can just be slid out of its rubber mount, unplug and slide out. To remove thermostat the procedure is :--(if in case you require) You'll have to remove the shroud, or lift it up, remove the fan. Unclip and slide the hoses off. Remove the 1 13mm head bolt, loosen the 11mm on top for the engine hook, release the 3-4 10mm head bolts. and pop the thermostat off. Thanks. Keep updated for any more query.
