G12 should have better corrosion protection, which is crucial on these engines. But you have to flush the engine properly, as G11 and G12 don't mix well.

90C on the dial - I forget, have you established how accurate that dial reading is, have you another gauge in your car or off-board, perhaps digital readout, of the same point of source for the dial reading to confirm that reading the dial shows?

The left analogue gauge in the console reads the coolant temperature between the expansion tank and the radiator.

Always is one click less than the one in the cluster.

As long as you have functional thermostat and cooling fan system, right pressure, no gas in the system and working radiator, it doesn't matter what liquid is in the system. 

Coolant has two jobs - anti-freezing and anti-corrosion.

OK, the "Official Skoda" repair shops here promote the G12 "because it's better for the sensors". 

They don't justify this but no one says in which sector is better compared to G11.

No sensors

@Thefeliciahacker what difference in performance you have seen now with G13 compared to the green G11 that you had?

I had green then g11 now G13. 

G13 has kept the cooling system spotless 

So no difference in performance? I mean in coolant, does get hot with more delay than G11?

So different location and relies on accuracy of of gauge and sensor/pick-up/wotsit/thingy and their pairing matching?

 

The car's original gauge is good enough for everyday general use but for your more precise testing and comparisons you need to stick with whichever is the most accurate measure and allow for it accuracy and precision.

Can not translate them to Greek, no meaning.

 

The factory takes indication from the coolant sensor and the after market from the lower hose, when the thermostat is closed of course shows much less, when the thermostat has opened and hot coolant returns to the expansion tank shows one click less because the lines on the factory are not so good in reading.

Interesting.

 

 

 

 

 

 

 

 

In the video some good points, some points that might be disputed and not enough information to gather how accurate the comparisons were., we are not told if the various coolants were claimed to be the same.  VW (stand up and salute) own labelled G12evo coolants in my experience at least are available at two different freezing point levels, have different VW parts numbers so are different and therefore should give different results to each in those test but both are VW own label G12eveo so it depends which one (r both) you put into those comparisons.  Depending on how the coolants are manufactured and by who actually there might even possibly be small variances in batches (but I don't know that for sure or at all).

 

As always there are compromises and more to it than those simple tests, basically you don't need worry about -25c but do want your car to warm up to operating temperature as quickly as reasonably possible and not too much over for too long.

Whatever it is that senses and transmit the temperature, possibly "sender" (of the information but it also has to detect the temperature), if it's an electric anologue gauge I guess the sender-transmitter is also electric but you might tell me differently.  Unless I misunderstood Thefeliciahacker put the factory ones are not sensors (or called sensors?).

The initial spot was there, before the factory one

 

 

 

but there was an accident (Chinese metal...sigh)

 

 

and i had to remove it from here.

Yes I remember that and the following post, I'm not the one putting up those videos and I've put my comments a few times before and after that video.  The high and low temperature point of the various coolants tested are only two points of measure are we are not told that the coolants are at equal concentrations and it doesn't tell us about their various levels of corrosion protection and lubrication.  All have service lives that are shorter than VW labelled G12evo at least.

You want the whole cooling/heating system clean inside and out, all parts and components working as they should, no additional hinderance from misplaced additional items or inappropriate insulation.

Very interesting results for HEPU 12 (i already have G11 from that brand) in boiling time and the time that needs to get heated for 2 'C only.

This G12 can be found in the local market, i wish the test had some other brands as Motul-SWAG-Febi-Valeo.

HEPU is a concentrate - I can't remember seeing or hearing in the video what ratio to water the concentrates were tested at, or what ratios the premixed were or their levels into minus temperate they were mixed for and rated at.

 

Test were simple electric ring to glass container at normal atmospheric pressure.

 

Whichever you chose to use just make sure it will be easily available in the future so that you can stick with it and not be mixing unknown factors in different liquids again.

It's because you can keep it at least for 5 years or is superior to the G12 in a specific sector?

The only factor we should care is anti corrosion which is superior 

The flush product arrived, in purpose i bought one that is mixed with water after the coolant drain, i don't want to add anything in the coolant again, enough trouble i had.

I will make few kilometres with the heat on (that's for the heater core) and then to the repair shop while it's stii warm for the drain.

 

Which one you bought. Use it for a couple of days at least 

For sure, i don't believe the "work in idle for 10 min" which some labels say.

Wynn's.

Bye-bye G11, after 24 years we ''divorced".
