For repair shops, water pumps are a subject that regularly leads to customer complaints. The demands made of the water pump in old cars are greater than for new vehicles. The cooling systems become contaminated from use (wear and tear, ageing) and from possible repairs (replacing the cylinder head gasket, opening the cooling system). It is easy for particles to spread through the entire cooling system and therefore to penetrate the sealing gap of the mechanical seal and destroy the smooth surface. A faulty water pump and an insufficient volume of cooling water can quickly do a lot of damage to the engine.
So the “MEYLE Mechanics” show why it’s important to flush the cooling system in their latest video. And in the process they explain how to protect a water pump from wear and tear and breaking down.
