Genuine BMW MINI Coolant Expansion Tank - Cooper S
The MINI Cooper S’s plastic coolant expansion tank is extremely susceptible to secreting coolant from anywhere around the middle seam. If your existing expansion tank is suspect or is diagnosed as leaking then replace it immediately with this genuine replacement. These are a very common failure on many BMW MINI models! As the coolant system is pressurised there is a chance that a leaking coolant tank can explode and deposit its content all over the MINI’s engine bay. Replace yours before a catastrophic failure leaves you stranded by the roadside. Quite simply don’t risk it!
Note: Supplied with genuine BMW MINI replacement expansion tank cap as well.
