Right guys I need some advice

Took car to indep bmw specialist.

Changed coolant drove 5 miles down the road. Car over heated.
Called garage turned out they hadnt closed the high pressure cap and the coolant just went

So they waited an hour used warm water and coolant to fill up max level on tank.

I drove off about 30 miles no problem kept checking amount of coolant always on max.

then left my car for three hours and the coolant has dropped down to mid way.

Drove my car another 10 miles and the coolant has dropped to minimum.


Any thoughts

they have not bled the system when they have changed the coolant hence the reason the level keeps dropping - whats happening is as the air purges itself out the system the coolant level drops. you might also find your heater doesnt work properly until the system has been bled properly due to an air lock. there should be three bleed screws/nipples in the system which need opened until air stops coming out of them.

they can be a right ***** to bleed as well :-)
