Checking the tightness of the cooling system
1. Are the water hoses going to the radiator, engine and heating system tight? 2. The condition of the hoses can be determined by squeezing them. Hard, porous...

Checking and topping up the coolant
1. It is best to check the coolant level when the engine is cold, since in this case there is practically no pressure in the cooling system. 2. When the engine...

Replacing the coolant
1. Use the expansion tank cap to relieve the pressure in the cooling system, then remove the cap. Be careful if the engine is hot: risk of scalding! 2. Remove...

Filling the cooling system with antifreeze
For reliability, even in summer, you should use a mixture containing at least 40% antifreeze. However, if you frequently add only water, the concentration of...
