I need to do the task 2 times, one for heater core and one for the radiator. With the thermostat closed (the car is cold) would be no coolant flow in the upper hose or to the expansion tank.

I have replaced my ECU, no problem with the new and the existing immobiliser of the car, the programmer did his "magic things" and works fine.

No morer additives for me, i will try to take some photos from inside the expansion tank to see if there is muck on the side walls. I wonder a combintaion of hot water and white vinegar for (fast) in-out procedure inside the heater core won't help?

Different Motorsport world, racing in oval tracks, mainly RWD, lot of displacement engines, 0-60 mph, dragster, big size car body, very wide tyres and donuts,ugly masks (car grill), no metric system etc which don't fit to our ways. First time i heard about Quick shift was before 25 years, in the beginning there were negative comments (too tight, too stiff) from the first drivers and was very expensive here, now things changed but no kit for Felicia. In the photo the gear stick is already big in height, in Felicia if i make it shorter will be like this:

In country yes, as i said i have done it in the past but in City it's very difficult. All the videos from this work are in a garage-country home-repair shop. Nah, i am going to the G14 that will show up in the future, always one step ahead.

Oh, so it's not for us.

The In-Out hoses for heat core are not so convenient as they look in other cars, the one yes it's very accessible, the lower which goes to the engine block (if i remember correct) it's difficult to reach it's end.

Vauxhall isn't the right side steering wheel of Opel in UK? American cars have many differences with European, i just read, can not apply exactly of what they say. I have replaced some parts in my Felicia few years ago, the gear lever was a bit ''loose", now it's OK but i don't want to shorten the upper part of the lever.

https://www.wikihow.com/Flush-a-Heater-Core I have done it many years ago back in birthplace where i had space and a garden water hose available. I can not do it here now, maybe in the future i will go to a shop with proper equipment (an example) when i change the G11 to G12 because they say it's better although so many years i have not overheating problems with G11. @Thefeliciahacker has G13 but i don't want to go to far.

As i have seen in other cars as MX-5 Miata the new lever has bigger length below the ball.

I don't want to open new topic, i found this while searching for the same thing. ''Krátké řazení Škoda Felicia'' is in Cz so if someone search with that key-word: https://speedpro.eu/produkt/kratke-razeni-skoda-favorit-felicia/ https://autobazar.hyperinzerce.cz/auto-tuning-ostatni/inzerat/56276645276713241645-kratke-razeni-felicia-1-6-nabidka-brno Looks like repair work.

You means this? https://haynes.com/en-gb/tips-tutorials/what-is-car-heater-matrix This is in the back of the whole system, has 2 hoses (in-out) but i can not remove it by myself.

Since i removed this dirty expansion tank i have done 2 coolant changes. The coolant sensor is clean but i can not know what's happening inside the engine. I will try to take photos of the new expansion tank (walls, bottom) for any signs of muck.

Mine says, every 2-3 years, no need for more often because the gap only opens does not close so won't get any worst. I don't know if he is right or wrong. I have an MPi, so it's 0,25 IN and 0,20 OUT. Every year valve adjustment no matter the mileage? New gasket every time?

That's the way Men here in Greece speaking about their cars (even when they were in the Army), they give them female names. Every year there is a gap change? You adjust them all the times? Or you inspect them ''just as precution"?

I t was a difficult task, one hand holding the plastic tank and the other hand the Dremel, small pieces like filings everywhere even towards my face. This is the lower part, from there the hose goes to the radiator. I said the mechanic to remove the old coolant, fill it with water, rinse, fill it again rinse and then add distilled water and new antifreeze. No glitters or sludge was found in hoses, i personally check it even the coolant sensors was clean, no residues at all. According to the theory that when something boils the bubbles-lathe goes to the top and stays in the side of the utensil? Examples: https://www.argiro.gr/wp-content/uploads/2018/02/kameno-gala.jpg https://www.newsitamea.gr/wp-content/uploads/2014/10/med_gallery_447_8_96432.jpg The new coolant has about 450 Km on it, many times checked at night with flash light in purpose to the any glitters ''shining", nothing yet. The sides of the expansion tank are 95% ,only a small mark on one side but nothing serious. Except waiting and if necessary changing again the whole coolant and install a new expansion tank i don't know what else can i do. 🙄 No radiator cap on Skoda, there is only one on the expansion tank and the old and the new were clear. No residues (muck or glitters) on them at all.

Scratching the sludge. The ''glitters".

In the past (no internet, no forum, no pdf manual) we had major problem, only some old mechanics which knew Favorit wanted to work in a Felicia and we didn't knew anything except what the magazines wrote-stories by other drivers. Now he have Haynes, service manual, forum to ask for help there is a lot of knowledge from the owner. Fancy, famous repair shops (even young ECU programmers) don't want to work with it because they don't want to get their hands dirty and will have no big profit, they prefer newer models with ''come-i install-you pay a lot-go'' procedure.

Oh God, did you got any bad smell inside the cabin?

I have removed that expansion tank and i decide to cut it through to see how was inside and the result was shocking ! The most disgusting water expansion tank view that i have ever seen.

Same here in Greece but with he (Local) young ones, they have that ''wise guy'' attitude with OBD scanner-laptop in their hands, a robe like doctors and disagree with everything you say to them. In case they don't know they reject you ''it's an old car, i don't have the programme for this car, no bulletin, my supplier does not have original parts for this, not worth the cost" and other excuses. Thankfully we have some old mechanics and some non Locals (young, non-Greeks) with smaller not fancy repairs shops which accept to work with an old car. By the way have you ever take measures for fuel consumption in City-Highway?

Few years back i bought a new radiator fan, i learn by the hard way that the cables on the plug were posisioned wrong and the 2 scales of fan speed were in reverse. https://www.briskoda.net/forums/topic/485671-bosch-radiator-fan-for-felicia-help-wanted/?do=findComment&comment=5454358 No one made a test before they put it in a box for distribution to the parts shop (so also to customer).

Just before installation. Finally i have access to the throttle cable any time. I have already done 30 Km in City Traffic, the rest of the test will be in Highway to see the Fuel Consumption difference.

Count the rpm drop in gear change, make the change in 5000 rpm and make the same change again in 6000 rpm, then see where you are in the 1st change and where at the 2nd. The top performane for my car is above 5100 rpm.

Velocity Stacks with foram filter, very interesting but i am sure @Thefeliciahacker will disagree with them. Here in GR we call them 4 throttles mainly for ''street racers".
