A little water pump leak ...

[THE ZUKE]

Sorry, I thought you had a small block. The advice to check using a paper towel sounds pretty good to me. 

No problem

Your cooling system may be self leveling itself. Where are you finding the coolant? If the WP is leaking the coolant will end up on the engine harmonic balancer, then it will drip down on the K-member. The engine looks dry in those photos, Is the coolant resting on the floor beneath the overflow hose?

Then there are some wet marks on the 2 pictures where we see the big black piece under the front of the engine and the pump. By the way the puddle is on the ground and shifted from the WP. I followed the overflow pipe and it is the opposite of the puddle under the recuperator on the right of the radiator. My question is: 2 inches of liquid cooling over radiator elements is not too much? Next weekend I'll leave 1/2 inch of liquid above the radiator elements. Go drive a little and then see if the puddle occurs. Today I started the cuda, I let it rise to its temperature for a little while, then I stopped the engine. An hour later I went back to see if the puddle arrived. There was nothing under the car. It's really a crazy stuff, this phenomenon.

It may be filled too high. If it didn't drip today then try if for a few days without filling it up. The level depends on a lot of things, rad cap pressure, radiator material, thermostat etc. I assume you have tightened all hose clamps with a screwdriver?

if you have a stock rad there is a metal strip visable under the filler neck , that is the fill line

Thank you, I didn't know this information. The radiator is no stock because it's an aluminium model.

Yes I tightened all the collars. At the end of the week, I will remove some water because I'm pretty sure there are too many. It's really odd that the puddle is only formed when the engine is hot but not if I run it in slow motion. As soon as possible I will go out and on returning, I will stay in front of the engine while it is cold. To try to find where the water is flowing when the engine is really hot.

Bad and good news, there is a very small leak in the liquid cooling circuit. 
I drove 15 miles, coming home, there were traces of liquid cooling but nothing serious.
Before going off, I had to remove more than one liter of liquid cooling from the radiator because the level was really too high.
For the moment, I do not know exactly where the leak is but at the end of the afternoon I cleaned everything in the front part of the engine and under too.
Tonight there are 3 drops of liquid cooling on the big black crossbar where the front axle is and also some dripping on the pulley under the water pump.
The leak is hidden behind the pulley.
I just ordered all the joints and also silicone (To apply yours advices).
I will put pictures when I do the disassembly and the replacement of the joints.
Before it is necessary that the material arrives at my place. LOL

Hi guys, 
News of the small leak of liquid cooling.   
After removing the first part of the water pump.
The seal was really not beautiful, without silicone and very thin ...  but the pump is recent.
It took me over an hour to remove all the small pieces that remained stuck. 
I followed your advice by putting silicone on both sides of the new gasket and on the four screws.   
Result tomorrow evening when I will put the coolant back and I run the engin.

A little of topic, but your car looks like it is a very nicely done car. K member, etc look nicely painted and assembled. 

Looks like a Fram oil filter though..might want to pick up a better quality oil filter.

Thanks for B-BLUE 
So I will say yes and no because everything is not yet at the top on my Cuda. 
Since she arrived home (around November 15, 2018), I only drove 40 miles.
In France we are in winter, it stays in the garage because the weather is really bad for more than 2 months.
I take this opportunity to make or redo what is wrong or is to improve. 
I will change the oil and replace the filter just before spring. I keep your link, thanks. 
The topic about filter is interesting. 
In two weeks with a friend we will replace the DA box with a Borgeson.
I will take pictures for those who are wondering.

News of the day 

I received my new water pump (an Eldelbrock).

It seems really better than a Mopar perf, the finition is better than the other one.

I have a question, where is the good place for the little hole (Have a look on my picture)?

I guess it must be down but is that it? 

Why do the 2 pumps have 2 legs different from the 2 others? 2 do not have the same shape as the 2 others

[RUNCHARGER]

The hole points down.

the casting differences around the mounting holes affect nothing ,  the squared casting goes to the top on both
