I could be wrong but it looks like this is leaking coolant. It's right of the waterpump. I saw someone else post this particular part and a comment about the plastic connector being the culprit, but I have not been able to find that post again. This is the only leak I've found but I haven't had a chance to look at the rear crossover yet.

 

That is a quick disconnect fitting on the water pump, its not serviceable, you probably will need to replace the pump.

 

Good point and has your water pump and plastic cooling hoses been changed yet?
Since it's a small leak now I would gather the parts you need as there is a number of them. The rear water manifold is another leaker and it requires the SC to come off.

This leads to the next question? How is the SC snout? Making any noises?
It helps to tell us what car you have? Full info.
Maybe where your at too as this is mostly US people so we are not familiar with some of the options not sold in the US.
Glad to see you caught it early too!

Thank you. I actually thought this was a separate part of the water pump and just checked my replacement and see what you mean. Okay, just waiting on 2 more things and I can do this!

 

Yeah I have replacement parts except for a couple still coming. I have not been able to spot a leak on the rear manifold yet so I'm not sure I need to do it yet. My upper pipe is the newer version already so not worried about that, though I will upgrade it if I need to replace the rear. I'm hoping to avoid pulling the SC.

 

Good Morning! We have tried to find that small part of the water pump and have come up empty handed. It really should be a serviceable part since all of the water pumps seem to leak at the same spot.

 

I think you have seen this but if replacing those plastic cooling pipes we now have an aftermarket supplier that has released Aluminum versions!
Several guys have installed them and no problems reported.

Al. Cooling Pipes

There is also a possibility they will release the rear water manifold in Al. as well. This would be a massive step up in the reliability of the cooling system which is our number 1 problem area!
