Warning: do not attempt to remove the expansion bank cap while the engine is hot - you risk scalding yourself. Do not leave the coolant container open for a long time as it is poisonous.
Prevention
- The closed cooling system does not require regular topping up of liquid. If you have to do this often, then there are leaks in the system. Check radiator, all hoses and connections for signs of leaks. If a leak is found, fix it as soon as possible.
- Use antifreeze all year round, not just in winter. Do not top up the cooling system with clean water, as antifreeze lowers the boiling point and raises the freezing point.
1. The coolant level depends on the engine temperature. With a cold engine, the fluid level should be between the marks "MAX" And "MIN" on the side of the tank wall. With a hot engine, the fluid level may be slightly above the mark "MAX".
2. If it is necessary to add coolant, wait until the engine has cooled down. Slightly unscrew the cap of the expansion tank to relieve pressure in the system, then unscrew and remove it.
3. Add a mixture of antifreeze with water through the filler neck of the expansion tank to the level of the mark "MAX". Install the cover and tighten it securely.
