Hi there!

Merry Christmas to all!

I hope there are some enthusiasts who still check the forum despite holiday as I have an annoying issue that needs help badly. I'll have 2 weeks off, and I wish I could solve this during this time.

I recently had a bad coolant leak on my Sonata 02 V6, it was behind the air compressor, and it fitted well with a bad water pump leak. I did a water pump - timing belt job with a kit buying from Amazon in trying to fix it. However, after the replacement, there's still a minor leak, at similar site, only when engine is hot and coolant system in high pressure. And, a strange thing is that the leak has green color like the coolant but it look oily and even has some oil smell. It does not drop down like water but oozing and spread along surface and thread just like oil. See attached photos.

I'm wondering if it is coolant leak from water pump again and coincides with some oil leak, or it's oil mixed coolant leak from somewhere else. I'm ready to go back in to the water pump if it's a bad one, I just wanna make sure there's no other causes of the leak, esp the oily appearance of the leak.

Thank you in advance! And, have a great holiday!
