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