| Symptom |
Possible reason |
|
Overheat
|
Level of cooling liquid fell in system (see. Head Routine maintenance of the car). |
| The driving belt of the water pump is faulty, or adjustment of effort of its tension (is broken see. Head Routine maintenance of the car). |
| Passableness of a radiator is broken or its lattice (is blocked see. Head cooling System). |
| The thermostat (is faulty see. Head cooling System). |
| The radiator cover (is damaged and does not hold pressure see. Head cooling System). |
| Installation of a corner of an advancing of ignition (is broken see. Head ignition System). |
|
Overcooling
|
The thermostat (is faulty see. Head cooling System). |
|
External leakages of cooling liquid take place
|
Hoses are damaged mechanically or as a result of material aging, or weakened fastening them collars (see. Heads Routine maintenance of the car and cooling System). |
| The epiploon of the water pump (is damaged see. Heads Routine maintenance of the car and cooling System). |
| The radiator, the heat exchanger of a heater or broad tank (is damaged see. Head cooling System). |
| Tightness of drain jams of the radiator/block of cylinders is broken, or vyzhimny jams of a water shirt of the block of the engine (are damaged see. Heads Engine and cooling System). |
|
Internal leakages of cooling liquid take place
|
Laying of a head of cylinders (is punched see. Head Engine). The head or the block of cylinders (are burst see. Head Engine). |
|
There are losses of cooling liquid
|
In system too much liquid (is filled in see. Head Routine maintenance of the car). |
| Occurs vykipany cooling liquid owing to an engine overheat. |
| External or internal leakages of cooling liquid (see above) take place. The radiator cover (is faulty see. Head cooling System). |
|
Circulation of cooling liquid is broken
|
The water pump (is faulty see. Head cooling System). |
| The cooling system (is blocked see. Heads Routine maintenance of the car and cooling System). |
| The driving belt of the water pump is faulty, or adjustment of effort of its tension (is broken see. Head Routine maintenance of the car). |
| The thermostat (is jammed see. Head cooling System). |
