Yesterday, I drove home from work and was dropping something off at home before running out again. In the 10 minutes I was inside, about half of the coolant was under my car. The coolant was leaking right underneath the oil pan. The car did not overheat while I was driving the 2 miles home and the leak slowly stopped under my car.

I checked all the hoses and can't find any leak around the coolant hoses nor is there any leak from the radiator. My water pump has been laboring for quite some time and I was planning to replace it soon (already bought the part). It seems like this is the place where it is leaking. Does that make sense? Is this a simple R&R or could it have damaged the engine?

Thanks,

Alex
