The prevention

Works are carried out on the cold engine at observance of safety measures (antifreeze is poisonous).

1. Turn away a stopper of a mouth of a radiator or a broad tank.
2. Substitute the pallet and two flat-nose pliers turn away a drain stopper of a radiator (it is specified by an arrow) and merge a liquid. If the stopper is not provided, disconnect from a radiator the bottom hose.
3. Check up a condition of hoses and collars of system of cooling.


1. Wash out a radiator a stream at its finest (deletes only a deposit), if necessary wash out a special washing-up liquid (deletes rust stratifications). If to wash out a radiator it is not possible, or if there are appreciable damages and a leak, remove a radiator and hand over in repair.
2. Disconnect a tank hose, merge a liquid, wash out a tank and dress a hose.

Refuelling of a cooling liquid

1. Tighten a drain stopper or attach a hose.
4-cylinder engines
2. Fill in a liquid (in the ratio 60/40 waters and antifreeze) before radiator filling. Fill in a liquid in a tank to the bottom mark.
3. Without closing a stopper a radiator, warm up the engine before thermostat opening (it is felt on heating of the top hose).
4. Stop the engine and after cooling fill in a liquid to mouth edge. On engine M40 turn on заглушку a ventilating aperture at the top of a radiator and add a liquid to вытекания liquids. Turn заглушку.
5. Press on the top hose, having removed thereby air then turn a radiator stopper.
6. Warm up the engine and be convinced of absence of a leak.
6-cylinder engines
7. Turn on заглушку a ventilating aperture on the thermostat (it is specified by an arrow).
8. Fill in a liquid (in the ratio 60/40 waters and antifreeze) to вытекания from a ventilating aperture. Tighten заглушку.
9. Establish a radiator stopper, warm up the engine before thermostat opening (it is felt on heating of the top hose) and slightly having released ventilating заглушку, let the air out. Tighten заглушку after the termination of an exit of vials.
10. Repeat procedure before full removal of air.
