Hello all, I am trying to fix a coolant leak that gives me the warning low coolant lights. I think the leak is from the water pump vicinity because I see the fluid sprayed at the top of the cylinder collected in little crevices near the pump etc. At first I thought its the water pump. However I took a closer look and saw a brass pipe (Water Pump Drain Tube) coming out of the water pump that is already badly corroded at the location where it bolts onto the water pump. I am suspicious that the water start spraying out this corroded section at highway driving speeds, and drains the coolant. So I am going to try replacing this tube first and hope to avoid replacing the water pump as it is a big bad job.
I have on hand a Water Pump Drain Tube, however it appears to come with out as gasket. My question is does it requires a gasket? where it bolts onto the water pump? Should I go back to the dealer and buy a gasket for it? Thanks!

Hello Everybody,
I am initiating the fixing of the coolant leak. I got my tools together and went to the car. I started the car and immediately I see a spot of green coolant drops onto the area just below the thermostat housing on the pump (see photo). So I am pretty much sure that the pump is leaking.
I wanted to start removing the fan blade but notice there is a piece of plastic surrounding it (I guess we call it Fan Shroud here right?). I tried to remove it but the fan blade is in the way, and I am not sure how I can remove it.
One other thing, after reading posts from here, I went and bought a Snapon FLXM13 tool hoping it will help me remove the 2 rear bolts on the water pump. But guess what? It might be useless. I looked at the visible front bolt on the pump (see photo) and saw that it is not a normal hex nut type bolt, but the reverse type where the hex shape is inside. See second photo. Since this unpleasant surprise is thrown at me, how can I modify the FLXM13 in order to use it? Not a nice situation at all.
Thanks in advance for any help.
