shows how much time a driver needs only for the Heater Core to pull out. He Is speechless till few minutes of the end of the video.

its a PIG OF JOB if you don't have to do it DONT

road to reach the end of the A

You have to remove the passenger wheel and you will gain good access, but no, I did not replace that hose, funnily enough because I couldn't source it new

Here are 2 photos from inside the expansion tank, isn't compleately clear.

 

 

 

 

 

I want to do a 2 stage flush, first with a 80% of a radiator cleaner (as Liqui Moly or Wynn's) and the existing coolant BUT then another one with the 20% remains and tap water.

I wonder it's absolutely necessary for the radiator cleaner to work ONLY with coolant? That 2 stage task won't clean the whole system better?

Try asking the manufacturers but I would not be surprised if they only say they can recommend using their products as the directions on their packaging and data sheets but it might depend on who you speak to at the companies.

 

Doing it the way you want is diluting the cleaner from what is recommended on the first stage and a very diluted cleaner on second stage and you will still have to flush thoroughly to get everything you can out of the system.  Better IMO would be 100% on first stage then thorough flushes and back-flushes until the water coming out is very clean.

Different approach, first the coolant out and later the radiator flush additive with water.

I don't wanna mess with the heater core especially when it's positioned in such an awkward place.

 

 

 

When i finish with this project i will replace the coolant expansion tank and i will take photos from inside, no i will not cut it as the previous because it's a job that will create lot of detritus in my balcony.

First impressions: i left the car to the repair shop, later the mechanic said that immediately the additive start to make something like "chemical reaction" and after few hundred meters (to get the coolant hot) saw some dark spots on the expansion tank (now has distilled water and the additive which also has clear colour).

So there is still some muck left inside the system, i will know more in the next days because due to hot weather i took my motorcycle to go to work.

Tomorrow i will have in my hands the old expansion tank (install a new one) and i will post photos of any remains.

Let's hope that in the new one i wouldn't see anything and the whole system will be clean after 2 flushes.

Here are some photos from previous expansion tank, the last with G11.

 

 

 

 

 

 

 

As you can see still there is some muck inside,not as the first one but exists. I see no glitters by the way.

 

 

 

 

 

The arrow shows the exit of the tank

 

 

 

 

 

from there via hose goes to the bottom of the radiator. As you can see there is no muck stuck in there.

 

 

 

 

 

 

 

 

Lets' hope that i will never see again such a dirty expansion tank. Now i have new with G12 which everybody says about it ''Oh, you put G12; the VW one" because in their mind the G12 is interwoven with the VW group.

As for the road test will take some days, we have high temperatures here and it's very difficult to drive in City without a/c (i want to make comparison with the G11 in same situations so no a/c).

 

I'm going to disagree with "everybody says". 🙂  Me personally, take many of the German and VW dictates, number, specs, with a pinch of salt and certainly with a car practically from the last century (indeed millennium) with an engine and system that weren't cutting-edge at the time wouldn't worry about G11 or G12 I would jus use an appropriate antifreeze/coolant but as with many other matters it's a lot about beliefs rather than anything being particularly good or bad, other than mixing different types or even brands together.

 

Cleaning (better thorough cleaning) and fresh appropriate coolant will help rather than leaving things as they were so it's all progress here, at the moment, for now at least. 🙃

I forgot to add the word ''here", especially the young mechanics consider that any VW group car must have at least G12 bcause ''the sensors read better". 😄

And where are these "VW" sensors actually made, do we know, are they specified for G12 and if so what about when G13 was the latest spec, as I put before if they want to keep up with the latest dictates then it's now G12evo.  There is only one absolute in life, well two but (some/all?) Greeks don't seem to agree with the second. 😄  

The mechanic made wrong in the calculation, now i about 45% G12 and distilled water.

I am inpatient to see in hot summer that combination how it will work, i have about 18 years to work in such a high antifreeze percentage.

Don't worry the residue distilled water (and whatever) left in from the last fill will reduce the percentage.

Where does the 18 years come from?

I had from about 2007 in my system a 20-25% percedage of antifreeze.

The lowest I've run was 30%

You had problem with my 40% and now you say you had 30% ?

Just one time! for just a few weeks when I saw poor performance, I emptied all out, it was due to dilution with distilled water, during the times the hg leak had started to progress

You had same coolant on since 2007?

Same type, G11.

I change it every 2 years.

Last photos before goes to recycle bin.

 

 

 

 

 

 

 

 

 

Let's hope that i will never see again an expansion tank like this in my car.

clean it with marbles and keep it as a spare

No, it's dirty, contaminated so it's a bad luck item.

The external temperature is hi here, about 42 'C so i can not drive without a/c.

I have to make a road test to see how the G12 works compared to the G11.

The "Glitters" chronicles continue. . . .
