So for two months the problem went away. Then water pump was replaced. Fortunatly the front grills come off easy be carefull touching the tubes of the radatior feel the temp of each tube idleing cold tubes indicate clogged coolant flow. Then shine a drop light or flashlight thru the core and see if there is junk keeping the air flow from the tubes. The whole radatior can be replaced in minutes. Spring clips and rubber at the top and rubber mounts at the bottom slides straight up and out. In the USA we don't get the 2.0 liter four cyl 5 series.
