i thought the coolant was very hot in my 645 to the point that its actually boiling and if i take the top off it isnt very nice to put your finger in there! So i changed the coolant - opened the rad and let it drain but didnt drain the engine block. Filled it back up today with 5 litres of concentrate then i was going to put 5 litres of distilled water in but i could only fit about 1 litre in. started engine and coolant still gets very hot. I spoke to a BMW specialist and they said these engines do get very hot (i had a 1.6 ford before so different type of engine i guess) but i thought before how hot the bmw ran.
Also does the electric pump procedure work on these cars where you hold the accelerator down as I couldnt get it to work.

bearman - thanks

As i was used to the Focus before which when opened the coolant was pretty "cool", this 645 alarmed me at the temp the coolant was at. All the pipes from the tank are really hot to the touch - something that wasnt on the Focus. I know they are completely different cars and the bmw engine is more than twice the capacity.
There is no coolant temp needle as well which is annoying.
