Discharge of cooling liquid
Prevention
Wait until the engine cools down before work. You watch that antifreeze did not get on skin or the painted body surface. Wash away the spilled antifreeze as soon as possible a large amount of water. Do not leave a container with antifreeze open and do not spill antifreeze before garage doors. Children or pets the sweet smell of antifreeze can attract, however, antifreeze is fatally poisonous.
| PERFORMANCE ORDER |
| 1. When the engine completely cools down, remove a cap of a jellied mouth of a broad tank. Turn a cap counterclockwise, wait until pressure falls down, then turn off a cap and remove it. |
| 2. If it is necessary, turn off fixing bolts and remove a protective guard from below of the engine for improvement of access to a cap of a drain opening of a radiator. |
| 3. Establish suitable capacity under a radiator, then turn off a cap of a drain opening and wait until cooling liquid flows down in a container. If the cap is not established, weaken a fixing collar and disconnect the lower hose from a radiator. |
| 4. When the stream of cooling liquid stops, reliably twirl a cap of a drain opening or connect a hose and tighten a fixing collar (depending on what is necessary). |
| 5. If you merged cooling liquid not for its replacement, then if it pure and served not less than two years, it can be reused though it is not recommended. |
|
Washing of the cooling system
If cooling liquid was not replaced long ago or the content of antifreeze was low, then eventually system effectiveness of cooling will decrease as channels of the cooling system get littered with a rust, a scum and other rainfall. System effectiveness of cooling can be restored, its washout.
The radiator needs to be washed out separately from the engine not to litter it.
Washing of a radiator
| PERFORMANCE ORDER |
| 1. Disconnect the top and lower hoses and all other necessary hoses from a radiator. |
| 2. Insert a water hose into the top branch pipe of a radiator. Direct a pure stream through a radiator and continue washing until clear water begins to flow from the lower branch pipe of a radiator. |
| 3. If after a wide interval of time clear water does not begin to flow, the radiator can be washed out with cleaner use. Follow instructions of the manufacturer of cleaner. If the radiator is littered very strongly, insert a hose into the lower branch pipe of a radiator and try to wash out it in the opposite direction. |
|
Washing of the engine
| PERFORMANCE ORDER |
| 1. Remove the thermostat, being guided by the instructions provided in subsection 4.4 then if the top hose of a radiator was disconnected from the engine, temporarily connect it. |
| 2. Having disconnected the top and lower hoses from a radiator, insert a water hose into the top hose of a radiator. Direct a pure stream via the engine and continue washing of the engine until clear water begins to flow from the lower hose of a radiator. |
| 3. Upon completion of washing install into place the thermostat and connect hoses. |

Gulf of cooling liquid
| PERFORMANCE ORDER |
| 1. Before filling of the cooling system with cooling liquid check that all hoses and collars were in good shape and that collars were reliably tightened. Do not forget that antifreeze mix with water can be used all the year round to prevent formation of corrosion on engine elements. |
| 2. Uncover a jellied mouth of a broad tank of the cooling system. |
| 3. Turn off the drain screw from above of a thermostat casing cover. |
| 4. On all engines slowly fill in cooling liquid that its level rose to the mark COLD in a wall of a broad tank. |
| 5. You watch an opening of the drain screw when filling the cooling system with cooling liquid; as soon as cooling liquid without vials of air begins to follow from an opening, install the screw into place and reliably twirl it. |
| 6. After the level of cooling liquid is correct, establish into place a cover of a jellied mouth of a broad tank and reliably twirl it. |
| 7. Start the engine and wait until it gets warm up to the normal working temperature (so far the fan of cooling will not turn on, and then it will be switched off). |
| 8. Kill the engine and wait until it cools down, then again check the level of cooling liquid. Add cooling liquid to mark MOVE if it is necessary, and twirl a cover of a broad tank. |
|
Antifreeze
Antifreeze always needs to be replaced through the required periods. It is necessary not only to maintain quality of antifreeze, but also to prevent formation of corrosion which will be formed otherwise as corrosion inhibitors lose efficiency over time.
Use antifreezes only on the basis of ethylene glycol which can be used in cooling systems with use of various metals. Percentage of antifreeze and minimum admissible temperatures of operation are specified in subsection 2.2.
Before addition of antifreeze it is necessary to merge all cooling liquid from the cooling system, it is desirable to wash out the cooling system and to check a state and reliability of connection of all hoses.
After filling of antifreeze it is necessary to attach a label on which the type and concentration of the used antifreeze, and also date of filling will be specified to a broad tank. In the subsequent it is necessary to add only antifreeze of this brand and concentration.
Do not fill in the antifreeze intended for the engine cooling system in system of washers of wind / back glass as it will damage coloring of a body. It is necessary to add special additive to system of washers exactly in that quantity which is specified containers with additive. |
