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

Wynn's.

With chemicals you are best to follow the instructions that the manufacturer gives unless the contact the manufacturer to see what variances can be successfully made.

 

Whatever way you decided to do the work it needs the thorough flush through with water until it comes out very clean (then back-flushing might release more, before forward flush again) is required, then allowance made for the amount of residue clean water left in the system before adding concentrate or pre-mixed coolant,

    Pure water will have the highest heat capacity,  so will boil slowest for a given heat input.

  • Water has heat capacity 4.186J/gK, ethylene glycol, used in antifreeze, 2.42J/gK. No need to experiment, you can do the math. Just make proper mixture for your weather conditions. There's really

  • 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. G12+ supposedly mixes better with G11, but I w

I drain the old coolant while was still hot ,i did in purpose so the hot coolant would circulate inside the heater core.

I added the product with distilled water only, i will do at least 30Km distance, drain, i will add distilled water only, drain and then the G12 plus distilled water.

Nah, after of what happened to my expansion tank no more risks especially in chemistry.

I don't know any other Felicia with G13 except yours, no experience for the compatibility, long term use etc. :shake:

Risky experiment is not following my advise 

The German engineers of VW since (according to below)  2018 use G12evo, who would go against the German engineers, but then they keep changing their specification so it depends on when you last changed the coolant, G12eve is "lifetime" coolant too.

You have advise me: no 10W-40 oil,no cheap wiper blade motor,

to don't put an ECU ship, no Koni shock absorbers, no Apex lowering springs, no buckets, no headers and the rest of exhaust, no K&N filter, no modify my air filter box, no 3 point harness seat belt, no racing brake fluid, no tinted windows, not cut my engine cover, no Led bulbs, no modify the incoming air filter hose, no G12, no hood scoop to protect my sponge filter, no HID fog light bulbs, no body insulation, no quick shift, no sport steering wheel...did i forgot something?

I asked one of the most famous drivers here in GR, he had racing with every Skoda model and had a full modified Felicia for road use.

He convinced me about the use of G12 and since i had G11 for 24 years i think it's time for a change and test.

I will raise the antifreeze concentration to about 30 or maximun 40% (i don't nedd a 50%, GR is not Siberia).

That means you lack fundamental understanding about the use of antifreeze in vehicular cooling systems

I have no ABS and airbag edition, the factory steering wheel is for granny driving style.

The HEPU G12 arrived today.

You two really need to get a room.

Or both use the 'ignore user' function on each other.

It's completely pointless quarrelling with each other all the time.

Yes and i do this in purpose because i am Bad and i like it. :evilgrin:

Motul says 33% and i had 25% for some years, now i will go till 40% but unfortunately the Winter is gone together with his cold starts.

Let's see how that percentage works in hot Summer days here.

 

@Breezy_Pete No problem from me, some times that's the GR way on forum conversation.

Maybe you two enjoy it, so carry on.

I have post it many times, the ABS + airbag were sold as ''package'' back in 2000 and the cost was 700 euro if i remember correct. 

I didn't had the money so i didn't add that ''package'' in my order list.

What's the problem with 40% percentage?

@Thefeliciahacker you do tend to be too rigid in some of your thoughts and expressions, too much faith and emphasis on engineers, they do make mistakes and not know everything and in my experience as a total generality rarely admit they are wrong and don't know something.  Not everything has to be designed and instructed by an engineer many things on cars have successfully been done on a car without them and advances made, possibly even by ignoring the given engineering wisdom of that time.  Same with some legislation which may or may not be amended later.  If you think the German engineers are always correct and the best then I think you might find you are mistaken at some point.

 

You do give lots of good advice and you can always put what you think, your opinion, your knowledge and experience but you must accept that others have different and possibly lots more experience than you currently have.

 

As I've put before I hope you modify and rein in what and how you put things to others when you are working with others that are not engineers, and to women, but you are young so probably won't accept this until you are older and picked up a few experiences from continuing with this, perhaps you won't as there are plenty of old men with similar attitudes..

 

I'm totally lost on a few items that you have put are wrong and even unsafe/dangerous but it doesn't matter as I'm not in GR, not that I can see how they apply anywhere, but again it doesn't really matter.

HEPU G12, i see no problem with 40% percentage.

-25 'C in GR is a ''never going to happen'' especially in an island.

Another test is finished this afternoon, i did it in purpose because i wanted to circulate the Radiator Flush in the whole system, for few minutes i opened the heat although the external temperature was high.

I drove 41 Km distance, City traffic, about 20 Km Highway, 2 Km Mountain Roads and the rest City traffic till i come home.

 

I ''own'' a photo to @nta16 for the coolant temperature, what the cluster gauge shows (before thermostat)

 

OTN(3).jpg.1581219dd45792ba387de1a484764aa3.jpg

 

and what the aftermarket gauge shows (between the radiator and the expansion tank).

 

OTN(1).jpg.68c7102e98a9507f8539c3ff44129610.jpg

 


There is a 4 'C difference in indications.

 

 

The gauge in car is not accurate. They never are.

It can depend on which gauge in which car but generally until proven otherwise it is best to take a gauge as being just a gauge rather than an accurate.  About 16/17 years ago my wife had a brand new car whereas my car, well some bits of it, were 34 years old at the time, and at least a few of the gauges on my car were more accurate than on her brand new car but my gauges were mechanical and could be calibrated, one was electrical though and was accurate.  British engineering rather than German engineering quality.  😁  😄    .

Felicia has VDO (German) gauges but i never trusted 100% because takes commands from the coolant sensor, in the past the needle was going up-down from the 90 'C line and made me crazy till i find the reason.

Some detritus in the bottom of that sensor, wipe is and voila, the needle move return to normal.

 

HEPU G12 (P999) is in my hands now, i have work to do the next days.

The car is in the repair shop, HEPU G12 (P999) in 40% percentage will installed with distilled water.

First impressions from the HEPU G12:

The cold start (the car was parked outside in the road but in shadow) took about 1 minute so the car reach the idle much faster that the usual 3:40 but it's too early for final conclusions, more in future cold starts especially in the Winter.

Same route, same speed, same time and the temperature of the coolant raised one click faster than G11 which means (together with the 1st) that the car is getting warmed one click sooner and that is good for fuel consumption.

After at least one hour on the road the temperature was a bit lower than the G11, in the console gauge was 84 'C instead of 86 'C which was with G11.

No overheating and the needle in City traffic (in the factory gauge) didn't raised so high as with the G11 and the console gauge show that the highest temperature of the coolant in that 50 Km test was 90 'C.

It's too early but as for start i am very happy with the new G12, to abandon the G11 looks that was a very good idea and as we say here ''Better late than never".
