I started to see small drops of coolant on the garage floor every now and then. Got under vehicle but could not find the source. Tried pressure testing the coolant system. The only place I see coolant is at the seam of the oil pan at the corner near the oil drain bolt. I do not see coolant above this point. Where could the coolant be leaking?

2012 Acura MDX coolant leak

 

I can't tell exactly where the picture was taken. The prime suspect would be the water pump. The water pumps starts to drip drip drip when it is about to go out.

 

That's right, it looks like the water pump is leaking. How long ago did you change the water pump? There is a possibility that your entire timing belt is in antifreeze and may break because of this.

 

I did the complete timing belt service last April.

 

So you yourself answered your own question, unfortunately your new water pump is garbage.

 

My guess is aftermarket water pump in that case. They ALL leak. The gaskets aren't thick enough. Honda or nothing, better off with an original pump lol
