D.FYLAKTOS

I was afraid of this and i asked for a cleaning few years back. Now i am using filter for kitchen hoods as an extra layer which stop everything (hairs, leaves, dust etc) but in my mind i have the thought to make a 3D printing oval shape receiver like a Casserole Dish with ### inside like this and add a filter like this after i cut it properly. For sure it's not like a stock constructior but it's far betetr than sponge.

Yes but what about the leaves, hairs from dogs etc, some of them may pass inside, where end-up? On the evaporator?

What's the benefits of G12 instead off G11 in our engine?

The weird is that in User Manual says: "TL-774 C Red colour 50% ratio" but D is red and not C and out engine it's an 1994 design.

At Winter where there is no a/c? They say that moisture on the sponge creates for in the windshield.

Yes but now the water goes in, the plastic tunnel ends inside the cabin (2 holes behind the seats).

So the G11 blue and the G12 red did not cover (at 30%) your expectations and you choose the G13 in the same ratio as better?

No sponge filter?

You had G11 (Green) before and for many years. For you the ''lowest'' ratio that can be used in Felicia is 30% and the ideal is?

@Thefeliciahacker If you had 30% G11 and 70% distilled water you think could face lubrication and corrosion problems?

The worst temperature all these 24 years for my Felicia was one day only at -4,5 'C in the year 2002 if i remember correct. Today i had a 200 Km trip, half in Mountain Routes and half in Highway (speed 100-120), the needle never touched the 90 'C line in the dashboard gauge, i don't have overheating problems, just that ''concern of mine" in Cold start.

@hzoltaan What gear oil are you using now? Have you ever use an additive like this? https://www.liqui-moly.com/en/pro-line-getriebeoel-additiv-p000070.html#5198 https://www.liqui-moly.com/en/mos2-antifriction-for-gears-p000009.html#tab-label-description-title

If you had 30% G11 and 70% distilled water you could face lubrication and corrosion problems? I think the minimum requirement is 20% antifreeze and covers till -8 'C. I have the assumption that if i have more antifreeze in my coolant (now it's too ''weak'') the engine will get hotter one click faster and will reach the 92 'C sooner than now. I don't know if this is right or wrong, thus i am asking.

@Rooted My primary concern is in Cold start which of the 4 combinations will reach first the 92 'C Watter Wetter says "Improves heat transfer and reduces cylinder head temperature" but in small routes in City i don't think i have that issue. @Warrior193 I never liked that 50-50 ratio, some drivers (which don't like to search things) and even some mechanics-seller promote it.

Some drivers here although live in hot climate use the 50% ,is there really need for this?

As we say here "you will pay this later". In this case (50% mixture) the radiator fan will work more often for example in city traffic compared to 20% in a hot climate?

The 50% concentration mixture from the first turn of the key in the morning (environment temperature) will reach the 92 'C first?

You can freely start talking.

I am on leave, in few days i will return home, i will change the water expansion plastic can and i will raise the antifreeze at least in 40% presentance (now it's 20%) to see if there is an effect in the time that the temperature reach the 92 'C.

I am in my old parents house far away from mine, i have with me only my phone, no proper equipment or time to do experiments or calculations. Thank you for your help.

For me which combination will reach first the 92 'C matters. Felicia came here with Green (G11), the manual says VW TL 774 C although some put G12 even G13.

@Rooted actually it's not 100 'C but around 92 'C, at this point (reading the red needle) my thermostat opens for 1st time. Has to do whith my Cold starts process, i think that the less antifreeze excists the more time needs to reach that point but other members maybe know better. I am on a trip now, when i return home i want to change the percentage of the G11 in my current coolant as an experiment.

First time asking that specific question, it's not about the role of antifreeze etc. It's crucial to know which of the 20-30-50% mixtures will reach the 100 'C first.

Gentlemen, i don't have the proper equipment to do the experiment so i am asking if a fellow Skodian member knows Chemistry far better than me. let's say that we have G11 antifreeze and 4 big boiling tubes-flasks or 4 big glass cans and inside there is: In 1st pure distilled water, in 2nd distilled water and 20% antifreeze, in 3rd distilled water and 30% antifreeze and in 4th distilled water and 50% antifreeze. We turn slowly the same heat source below to all 4 tubes-flasks (or glass cans), here is an example We measure by clock: 1) the time that each mixture will reach the 100 °C (then we remove it) 2) the time that each mixture after the 100 °C will cool till environment temperature. I don't care which of the 2nd,3rd,4rth will reach it's maximum point, i care only till 100 °C. According to your knowledge and experience what could be the results? Which of the 4 will reach the preset temperature first and which of 4 of them will cool faster?
