I replaced the hose that runs atop the radiator a month ago with the oem part. I had the expansion tank replaced about the same time. I have a leak that pools under the car, driver side front. I think the coolant sensor is on the passenger side, anything over on the driver side that I should be concerned about? The splash guard is wet when I look down at it from under the hood.
I'm right in the middle of the 100k cooling system replacement, I'm not taking it well. Any help is appreciated.

 

i did the water pump, thermostat, and hoses about 1 year ago on my 04/545.
There are 2 more hoses (1 main & 1 "aux" (to heater core?)) on the drivers side.
The main hose is probably not the leak, it is too far forward and easy to inspect.
The lower hose (to the heater core?) is accessible but difficult to change. The connections are down by the drivers side wheel well.
Hope you find the leak,
Good Luck, mike

 

Good info, thanks Mike. I'm taking the car in, I wanted to have some background when I talk with the SA.
