Asked by jpgirlmechanic Sep 14, 2017 at 05:27 PM about the 2001 BMW 7 Series 740iL RWD

Question type: Maintenance & Repair

What can I do?  On a 01 BMW 740il, radiator was replaced about a year ago.  Thermostat was replaced a few months ago. Front upper radiator hose cracked (plastic connector).  Replaced. Rear hose connector cracked. Replaced. Oil was overflowing from filter.  Did an oil change and replaced seal and filter.  Radiator just cracked today.  What is causing too much pressure to make all the cooling system to crack?

I have just learned from the Local BMW dealer that they replace all components the same time. I am using some after market and some OEM parts. There hasn't been any more leaks since replacing the hoses other than the radiator. I have been bleeding the system after changing each part. I may need to do better research on properly bleeding. I will be changing the bottle today.

Too much pressure implies that the radiator cap is not functioning properly.
