Diagram Bmw E39 Coolant System Diagram Mydiagram Online You don't want it spinning too slowly or too quickly. cooling system parts list. radiator. behr $137.30 (manual transmission) part# 17111436060. behr $139.29 (automatic transmission) part# 17119071519. expansion tank. part# 17111436381. genuine bmw $63.29. expansion tank cap part# 17111742231. Cooling system overhaul tips and tricks (e39) for v8 engine, it is very similar in concept in belts layout, see this diagram that i just prepared for you folks with v8 engine. when combined above link and this picture, v8 folks should be able to do cooling overhaul themselves. good stuff.
Bmw E39 Cooling System Diagram Written procedure; 1) with car cold turn on key to run position (do not start the car), set hvac system to 90 degrees and fan on low. 2) remove coolant pressure cap on expansion tank and the bleeder screws from thermostat cover and expansion tank. Due to complicated castings, extra hoses and preformed coolant tubes air can easily get trapped in the cooling system causing hot spots and, depending where the air gets trapped, reducing coolant flow. to purge the air out of the cooling system bmw has provided a bleed screws which should be used during a bleed procedure. 2) pressure. the radiator cap on our cars is rated for 30psi! most vehicles have a cooling system running around 14 17psi. so, this excessive pressure is putting a lot of strain on our cooling system. the hoses swell more, the radiator has to contain more pressure, etc. the balloon that is our cooling system has a lot more pressure inside. 3. Replacing the radiator, thermostat, water pump and hoses in my 2001 bmw 540i. torque spec for water pump: 10 nm (89 in lb)coolant pulley: 10 nm (89 in lb)the.

Use the airflow over the radiator, either from the cooling fans or airflow from driving, to cool the coolant passing through it. this helps keep the engine cool when the temperature gets hot. radiators can leak or get clogged with corrosion. either condition reduces the effect of the cooling system.
