Attention! The coolant level is checked on a cold engine.
1. Remove the seat (see «Seat - removal and installation»).
2. Remove the left side trim (see «Side trims - removal and installation»).
3. An expansion tank of the engine cooling system is located under the left side trim. The translucent body of the tank is marked with marks corresponding to the minimum and maximum allowable levels of coolant. The fluid level on a cold engine should be between the two marks.
1 - UPPER, mark of the maximum coolant level; 2 - LOWER, minimum coolant level mark
4. If there is not enough liquid in the tank, it must be added through the filler hole. If the level is too high, you must first determine the cause of the increase in the level of the coolant, and only then bring the level to normal.
Reasons for rising coolant levels
|Description of the fault
|Too high coolant level
|During previous checks, the true coolant level was incorrectly determined and an excessive amount of coolant was added
|We remove part of the liquid with a technical syringe or a rubber pear, bring the liquid level in the tank to normal
|Level does not change with engine temperature
|1. The pressure reducing valve in the filler cap of the cooling system has failed. The pressure in the cooling system exceeds the nominal value
|Replacing the filler cap (see «Coolant - replacement»)
|The fluid level in the expansion tank rises when the engine starts, and fluid begins to flow out through the expansion tank drain pipe. Air bubbles are visible in the liquid. The level drops when the engine is turned off
|2. Broken cylinder head gasket. Gases from chambers (s) combustion breaks into the engine cooling circuit. There may be traces of oil and gasoline in the coolant
|Replace the gasket
