Lastly in addition of getting this exact 50/50 mix. In the end I just filled up with 50/500 mix. I managed to get about 4L in meaning there is 1 LITRE of pure distilled water in the system. I would suspect over time the coolant level may drop a wee wee tad due to not being exactly 50/50 but I will just top up with pure antifreeze and keep a litre to a side and that way I know I'll slowly but surely get to that exact 50/50

I hope I don't sound patronising but I'd like to say "Jolly well done that man"! Your post is a very welcome addition to the reading on this forum. It certainly looks like you did the right thing by flushing it through. Probably never been done in the life of the vehicle judging from the "stuff" in those bottles. So glad for you that it turned out so well.

How did the bleeding go? No problems?

I'm looking forward to reading any more posts you might do in the future.

Kindest regards
Jock

No not at all, I appreciate the kind words. I genuinely love this forum people are so knowleable and helpful. Im on the corsaD forum and it is a ghost town except for a few of us left, which is a real shame. Really hope this forum keeps going strong even with puntos no longer being made. The bleeding seemed to go fine, open bleeder> wait for coolant 2 come out>close it back>squeezing hoses leftright and centre lol> and let fans kick in a few times>test drive. I dont drive my car as much as average people do due to working from home office, so not out of woods yet will bee keeping an eye for next week or so and keep people informed should anything be wrong

Guys, after full heating up engine when thermostat opens, can you press big hose from thermostat to upper radiator corner sofly by two fingers like I do? I thought when thermostat is fully opened, borh hoses from (and to) radiator should be hard like rock...?

Just from memory I think the radiator pressure cap has a blow off pressure of 1.4 bar? Seem to remember that from my Panda and the boy's Punto. If this is the case then you might expect the system to pressurize to somewhere around that figure when fully up to temperature? So, in "real money" that's around 22psi which would be felt throughout th whole system. If the hoses are in good condition - and therefore supple - I would expect them to feel quite firm but not rigid. If they are really quite easy to compress then probably the seal in the pressure cap has failed, however if you are loosing coolant the same effect could be due to a leak somewhere else in the system.

Thanx Jock. I,m not loosing coolant and temp gauge never exceeded half. My system on Punto III has no radiator pressure cap, I think that pressure is regulated through cap on water reservoaire tank. But I checked also radiator hoses today on my Fluence 1.6 and both are soft too...maybe little bit more firm than on Punto. I'm still thinking about possibilities of my "engine ticking issue on hot engine" and I checked valves, oil passages, cleaned oil holes, checked valve clearances, cleaned valce cover. Everything OK). So I thought what if there,s air in radiator (isn't), so I checked hoses temp by hand when engine reached operation temp...but temp of upper hose from thermostat increased slowly, and hose was very soft. Thats why I thought that thermostat keeps opening, but it stuck somewhere in the middle. I thought that engine isnt cooled properly and that can cause that ticking...I'll check it more precisely... Because I found infos that sometimes, even cooling system is overheated, temp gauge shows good value... And I don't want to remove thermostat to check it at home in boiling water...1st I needed to know if radiator hoses are soft or hard when termostat is fully opened. I saw other vids on YouTube and guys were able to press hoses by two fingers too...But I'll check it also with laser temp measurement tool. Plus - when I checked hoses to radiator and they had appr 60-70 degrres of Celsius, fan starts blow for few seconds. Thats another indication that maybe my termostat isnt opening fully. And engine was overheated by previous owner, and it maybe could damage thermostat...

When doing such hose temperature checks, the car was stationnary - right ? So there was no air flow thru the radiator, resulting in coolant temperature increase... and fan start. Not an indication of failing thermostat, though that doesn't indicate a good one neither !! On modern cars the pressure cap is almost always on the expansion tank.

Isnt a ticking sound usually the cam lifters?...

bernie - car was stationary, but fan is spinning by info from coolant temp sensor which is near thermostat. And hose from term to radiator wasn't hot when fan started. My radiator has no cap, only bleeder valve on left upper side (when you are looking on engine). Also Renault Fluence 1.6 has no cap, Megane 2 and Fiesta hadn't cap too...

nikrox - what do you mean "cam lifters"? Because this is pure mechanical touching of cam lobe vs shimm on bucket. But this high ticking is different sound and valve clearances are ok. And it starts only when car reach operational temp and stops. It's also realted to outside air temperature - for example today: car was on operational temp, outside temp was 13. I stopped for a while and listened idle. I doesn't hear anyting, but after 30-40 seconds of idle it started ticking. First only weakly, but after another 1 minute sound became louder. That's because car wasn't in move and engine wasn't cooled by incoming air from outside. On cold engine there's no ticking at all, never. Only when car reach operational temp and isn't moving. So definately it's temperature-related.
That's why I asked question - when your car is on operational temp and thermostat is fully opened, if you can press upper radiator hose by 2 fingers and press gum completely?

Sorry..I was thinking of hydraulic cam lifters

OK, I knew that And make things more strange - when I touched IN/OUT hoses from/to radiator, upper side of hoses was warm, but their bottom sides were completely cold ??? Psycho?
Additional - water pump was changed (but ticking was there before), new coolant water, radiator without air. I really suspect thermostat that was damaged by overheating by previous owner and isn't opening completely, but stucks "somewhere in the middle". I'll check it more precisely

Ok guys, so everyting is OK. I checked it today and was sure that engine is on operational temp. Hose to radiator was hot and firm with same temp as other hoses, and hose from radiator was colder. So OK, hoses were 3 times firmed now. Last thing is to check for dirt between radiator and AC condenser radiator. Unfortunately theres no access, I think that I have to remove bottom plastic cover...

I believe you'll have to remove the bumper and front cross member too ... see recent post about condenser replacement ...

Thank Bernie. I checked it today by eyes Because when I put light from engine side, I can see through both radiators Of course there's fan support but it's clean. Because I don't know car's history I thought if there can be some sheet of carton or something big... Little bit sad that ticking isn't caused by inproper cooling, because cooling sys is easy to fix and thermostat costs funny 10 Euro... But OK, engine overal is running well
