DESCRIPTION
With the expansion tank being exposed to high pressures and temperatures, the plastic tank is known to crack and leak (particularly at the hose fittings). Without the correct amount of fluid in the cooling system, your BMW can overheat, causing expensive engine problems. With the high failure rate of ageing tanks, we recognise that the market has been flooded with notoriously cheap aftermarket replacements. This tank is made by Mahle, an original equipment supplier to BMW. Comes complete with coolant level sensor.
HELPFUL TIPS
Make sure you have enough coolant on hand before starting the job.
