Hi every1
I thought I had a broken heater core and leaking in the floor board. So I by pass the heater core with some U shape hose now. However, I found another leak from underneath kinda like dripping not major leak. Its big enough for it to over heat rather quickly and bubble in the expansion tank. I went below and took some photos but still couldn't find where the leak is? Any1 with some experience may give me a few options where the leak maybe? Thank you!

But that is the transmission pan. How could coolant go there?

 

Leaking into the cowl? Check the cabin air filter to see if it is wet.
Also remove the drain hoses. 1. Confirm they are clear all the way to the outside over the transmission. 2, make sure the drain hole in the bottom of the HVAC box is not blocked.

hope this helps.

That is the transmission correct? That looks like water not coolant. Are you sure you got the system bled properly, you could just have a lot of air in the system

 

I got a broken heater core and its leaking inside the floor board as well. My floor board is still very wet even after I by pass the heater core 4 days ago. I think now that there are some remaining water in the heater core leaking underneath through some channels. Today the dripping is not as bad as yesterday. I may get a shop vac to vac the remaining water out of heater core just need to get the correct hose adapter. I just used water instead of coolant for now. That explain its just water dripping just coolant. Thank you!! I guess I just answered my own question
