Although it didn't cleaned the corrosion

You sure the corrosion didnt get removed with acid?

Yes, because I still see orange thing inside radiator. Don't what did I wrong. Solution I made was 400 grams of citric acid imto 4 litres of distilled water and ran engine for 15 minutes with T valve removed.

Its fantastic, Ive been doing citric acid flushes since decades now and have fixed a huge number of cars which had bad cooling system - partially rusty, clogged with gel, mineral deposits etc.

cheap and effective - same stuff is used to clean washing machines, kettles, steam irons etc.

soda flushing is a good idea, but just a long flushing is also effective if soda is not available.

did all 4 litres of acid mix go into system? - rusty orange scale didnt dissolve out?

No offense, but its normal to feed expensive fluidsto the vehicles when they are new (or when we buy them even as 2nd hand vehicles).But later we know that feeding such expensive items doesn’t bring any miracles.These are just gadgets which 8 out of 10 times doesn’t work. Specially their Ceratec,Octane booster, Radiator Leak Stop, are pathetic products and didn’t work forme. Infact its insane to use Radiator Leak Stop as it clogs the Radiator linesbadly.

Ive also seen this - usually its a young car owner, who got his first car and assumes that all such products will make the vehicle into something else.

I did use the all the water till fill up to the system. Yes it does dissolved out the rust an water came dirty but not all of it. I will share pic of inside radiator in the morning.
