BMW 5 series E39

1. If the car has just returned from a trip, before the beginning of procedure wait some hours before full cooling of the engine.
3. A heater in salon put on the maximum capacity.
4. After the engine has cooled down, uncover a radiator. If the cover has to be opened, when the engine has cooled down not completely, do it slowly and with observance of precautions to avoid burns, and remove thus pressure in system. Then turn away a stopper completely and remove it.

The cooling system is under pressure. The stopper acts in film only at temperature of a cooling liquid more low + 60С. For stopper removal put on it a thick rag.

5. Lift and establish a forward part of the car on supports. Remove the bottom guard of an impellent compartment, address to Section Check of system of cooling.

6. Substitute under a radiator pure capacity and turn away a drain stopper of a radiator. The stopper turns away the big flat screw-driver or a coin. Address to an accompanying illustration.

7. Substitute under the engine capacity and turn out a drain stopper (the marksman on an accompanying illustration) on the block of cylinders. The stopper is under a final collector.

8. Completely merge a liquid. While the cooler pours out, check up a condition of hoses of a radiator, a heater and collars (if necessary address to Section Check of a condition of components of a suspension bracket and a steering).
9. Replace defective hoses and collars.

The cooling liquid is poisonous. To throw out it, in particular, with a household waste it is impossible. The information on the locations of points of reception should be presented local authorities.

10. Screw a drain stopper with a new lining in the block of cylinders and tighten its moment of 40 Nanometers.
11. A drain stopper on a radiator tighten slightly. For this purpose it is possible to take advantage of a coin inserted into a cut of a stopper.

1. After full drainage of system wash out a radiator pure water from a garden hose so that from a drain aperture or the bottom hose pure water poured out. If the radiator has strongly rusted, is damaged or proceeds, it is necessary to remove and send it in repair shop to the expert in radiators.
2. The washing described above will remove various adjournment from a radiator, but cannot remove a rust and a scum from surfaces of the engine and a cooling pipe. All can be removed it by means of a chemical cleaner. For performance of this procedure follow instructions of the manufacturer of a cleaner. Before engine washing open a drain stopper of the block of cylinders.
3. On accordingly equipped models remove переливной a hose from a broad tank. Drain a tank, wash out its pure water and connect a hose.

1. Fill in a broad tank to edges with a new cooling liquid.

2. Open a ventilating stopper (the arrow on an accompanying illustration) above at a radiator, near to a broad tank, will not go yet a liquid which is not containing vials of air.

3. Open a stopper (the arrow on an accompanying illustration) on a tube of a cooling liquid around the oil filter, will not go yet a liquid which is not containing vials of air.

4. Close ventilating stoppers and add a liquid in a broad tank.
5. 525tds: here removal of air from system occurs automatically through the top pipeline of a separate broad tank. Ventilating stoppers here are not present.
6. Close a broad tank a stopper. Work of the engine with an open stopper, since is not supposed. It can lead to damages.
7. Start the engine. Establish a heater in position “WARM” (Warmly) also warm up the engine. Tolchkoobraznymi pressing a gas pedal support number of turns of the engine not less than 2500 rpm. In the course of removal of air from system level of a cooling liquid will fall to mark Max put on a broad tank.
8. Switch off ignition.

Add a liquid in system after engine cooling. Otherwise at отворачивании stoppers the burn is possible!

9. On the cold engine fill in a liquid to mark Max of a broad tank, address to Section illustrations “Check of level of a cooling liquid”.
10. Once again open ventilating stoppers and check up, that the liquid left without air vials. Close a stopper of a radiator and ventilating stoppers.
11. Check up visually tightness of system of cooling, in particular, joining of hoses and a drain stopper.

1. Start and warm up the engine so that the top hose going to a radiator has got warm.
2. Cautiously open a stopper of a broad tank.

Do not open a stopper on the hot engine, instructions in Section “Check of level of a cooling liquid” see.

3. Suck away a liquid the device for check of density and check up density under float indications. Address to an accompanying illustration. In our widths antifreeze should protect system to temperature-35S. It corresponds to a volume parity of water and antifreeze 1:1.

1. Close a radiator stopper, pass on the car and again check up antifreeze.
Visual check of tightness of system of cooling
2. Check up hoses of system of cooling on presence of a time. For this purpose compress and bend them. In the presence of the raised rigidity of a hose replace it.
3. Hoses should come far enough on the union. Check up reliability of fastening of hoses collars. If necessary replace collars.
4. Check up consolidation of a stopper of a broad tank.

Low level of a cooling liquid can be a consequence wrong навинчивания of a tank stopper.

5. If level of a cooling liquid often goes down without presence of any obvious leak check up system at the heated-up engine. If on the heated-up engine the liquid follows from an aperture under the pump of a cooling liquid, the reason in damage of an epiploon of the pump. Replace the pump.
6. Considerable loss of a cooling liquid and-or oil presence in liquids, and also a white exhaust on the heated-up engine specify in damage of a lining of a head of cylinders.
