Attention! When opening the expansion tank, hot steam or hot coolant may come out, cover the cap with a cloth and carefully open it. When the engine is hot, the cooling system is under pressure. If necessary, reduce the pressure before repair work. Use clamps of the appropriate series to fasten all hose connections. The arrows marked on the ends of the pipes and hoses of the cooling system must be opposite each other.
