VW Passat B5 2000 1.8 Gas ADR Engine: Coolant Leak & Fluid Exchange Connector Replacement

Hello, I have vw passat 1.8 gasoline, gas from 2000r engine code ADR. I have been running out of coolant for some time. These are not significant losses. I saw that there was a leak at the rear of the engine, dripped on the gearbox. I guess it's a stub pipe. I have already purchased https://e-katalog.intercars.com.pl/#/produkty...P108_196-O5725-krociec-ukladu-chlarzenia.html such an item. And here the stairs begin. How to name it .... there is no film (or I can't find it). I think the exchange is not too complicated but I will not do it without an instructor. I do not know if I want to buy any other sensor-style part etc. I would need some block diagram showing the order of works (what to dismantle to have a better approach etc.) Please help

Hello. I suggest putting the car back to the mechanic in a few hours. If you have no knowledge in this topic, I advise you not to do the work. And he'll find out exactly where the leak is from.

Unfortunately, for some time now I doubt "barn" mechanics and I can't afford asao. I am still waiting for help ...

There is no trusted mechanic a colleague does everything himself with this Passat?

no tire replace in vulcanization ... inspections at the station and the agent's ... Will anyone help?

I have just applied for this forum for knowledge

And how did you check that it is definitely a stub pipe and not something else?

as I wrote, fluid leakage and this connection is wet

Here almost all "barn specialists"
But we know that you need a 10mm wrench

keep going

I will give myself, and finding instructions on the internet replacing the metal piece takes less than 10 seconds.
The internet doesn't stop at youtube.

Hello,
I apologize in advance for lack of Polish letters but I do not have English windows.
In fact, there is nothing difficult about it:
You unscrew the elements that will hinder access to the connector, i.e. the air filter duct, I write it from my head recently I replaced such a connector in 2.0, then you put something underneath the car to catch coolant as it will leak.
You move the metal clip from the bottom hose, the plastic clip from the sensor, detach the cable from the sensor, unscrew the mounting screws and pull out the connector.
Before mounting, you wash the mounting places (I use acetone), you get new ones for the rings, unless they are included in the set I mean a ring for the head and the sensor and you fold.
