Capacity of coolant 740il - 2000 BMW 7 Series

SkyActiv engines, regardless of displacement, never fill completely (according to the dipstick) using the recommended fill volume. Your experience using 5 full quarts in a 2.5 liter is exactly what others have experienced.

Engine lubricant oil capacity: 4 liter / 4.2 U.S. qt / 3.5 imp. qt with filter change Engine coolant capacity: 6.5 liter / 6.9 U.S. qt / 5.7 imp. qt Fuel tank capacity: 65 liter / 17.2 U.S. gal / 14.3 imp. gal Transmission oil capacity: 1 liter / 1.1 U.S. qt / .9 imp. qt Final drive oil capacity: 1.1 liter / 1.2 U.S. qt / 1 imp. qt Battery capacity (Ah): 50 Spark plugs: Bosch F7LDCR, NGK BKR6EK

coil packs or plugs need looking at, failing that injectors may need a clean

check fan operation. If it has a viscous fan hub then replace it. Have a pressure test done on the coolant system. have a compression test done for head gasket/ cracks. Have a flow test done on the radiator to check for blocked cores. check the level in the radiator not the reservoir.

No fluids in an alternator

Are you sure you asked the correct question?

If coolant is not circulating there is either a blockage in the line somewhere or most likely you will have to replace the thermostat.

Make sure you have the right amount of coolant in the vehicle. Make sure your fans are running correctly. If they are not running, check the fuse. If all this checks out, it may be a bad thermostat.

CHECK FOR LOW COOLANT LEVEL.IF COOLANT LEVEL OKAY.SCAN VECHICLE FOR FAULTY COOLING FAN OR RELAY.AND SCAN FOR FAULTY COOLANT TEMPERATURE SENSOR.

look on the radiator next to the top hose connection, also on the thermostat housing there should be a small screw, bleed the thermostat housing first then the radiator

You have a head gasket leaking or cracked head.

Antifreeze is leaking into the combustion chamber and burning off.
Keep an eye on your coolant level, as it will decrease gradually.
