BMW coolant pump pump leak exposes 10,000 BMWs
A leaked BMW coolamp pump has exposed 10,800 BMWs in the UK, with the owners of the machines facing financial loss after the water pressure was cut by around 1,000mm.
The leaks were discovered on Monday in a BMW Coolant Flow machine in Stockwell, Kent, by a homeowner who said he noticed the pump was working intermittently, with his water pressure being cut by less than a millimetre.
The pumps are used to supply the cooling system to the BMW 3 Series, 3 Series R and 3 Series Coupe models.
BMW said the pump is being fixed and the affected machines have been returned to service.
The BMW Coolamp Pump is used to control the flow of water in BMW’s cooling system.
It’s a simple operation, which can take a while to get right.
But the BMW Coolamps are used in all of BMW’s coolant systems, which supply cooling to almost every vehicle on the road.
The owners of BMWs are now facing a potentially costly repair and a potential loss of earnings, although BMW said they are not facing financial losses at this stage.
It said: “The water pressure is a fixed variable that is adjusted by the pumps on the same day.
The system was set to be fixed at 7600 psi for the next 30 days, but we are now working on fixing the pump and will be back to normal next week.”
The owners said they had installed a water sensor to check their water pressure and had also installed a new water filter in the Coolamp to try to reduce the amount of water being used by the pump.
However, they said they were still unsure about whether the pumps were properly operating.
They added: “It is not yet clear whether or not the system is functioning properly.
We are in the process of getting the water checked by a qualified engineer.
We do not know if it will be able to be repaired or if the water will remain in the system.
The Coolamp pump was fitted in the 1970s and has been a source of concern for BMWs since it was introduced.
The machines, which provide a high flow of cooling, can sometimes be over-loaded with water, forcing the pump to work overtime.
The company has been working on a new Coolamp, which was introduced in 2019, which will increase the flow rate by 500mm.
