I came home today after driving and had coolant in the driveway originating from the left side front dripping near the oil pan bolt. I put the car on ramps and tried to find the leak. The leak does not occur when the car is running, only after you shut it off (which is common for a water pump). I saw some fluid leaking from the pipe that goes into the back of the water pump which is sealed with an o-ring. Has anyone ever seen this seal go? The car has 160,000 miles. It could be the water pump but it doesn’t look like it is weeping from there but it is hard to tell. The pipe that comes from the water pump has other pipes connected to it, but it doesn’t look like they are leaking. It looks impossible to get at the pipe that comes out of the back of the water pump. Any suggestions would be appreciated. I plan on taking the shroud off so that I can get a better look at where the leak is.
