Coolant leak 2007 Cooper
I come asking your advice. I have a 2007 mini cooper. About a year ago I had the radiator replaced as the coolant had leaked out the bottom corner of it. Appartantly that is a common fault with this car.
Anyways flash forward to the present day and low and behold its leaking coolant again. I noticed the level in the expansion tank had dropped to the Min level and so I topped it up. I filled it up ran it round and checked it after a bit. Again its dropped.
Could it be the radiator again? Any other thoughts? The water pump or the thermostat? Should I ask them to pressure test the system?
Just worried this is gonna cost me the earth and don't want to get ripped off by a garage.
Any help would be appreciated,
