TL:DR:
One day i was driving and suddenly the aircond blow out hot air. I thought aww shucks the compressor failed and i got to buy new one. Awhile later, the temperature shoot up and im 2 bars before reaching the max so naturally i just stop at roadside. Upon opening my bonnet, i can see the water shoot out from the radiator reserve tank hole and so i call for towing service to my workshop who is pro in radiator services. He just change the thermostat and teach me how to monitor the water level to make sure the car is okay.
I've a different take after reading the whole thread.One day i was driving and suddenly the aircond blow out hot air. I thought aww shucks the compressor failed and i got to buy new one.

At this point in time as desctribed above , your engine has already overheated to the extent,unfortunately, your immediate subsequent replacement of thermostat (which I speculate as wasn't faulty, as yet ) and air bleeding by your radiator pro couldn't help to reverse the 'overheated' engine condition , which was later diagnosed and confirmed by SC as being caused by a crack in cylinder liner No 2.
You did well in shutting down the engine soon though, but .........

As i check the water every morning as instructed, i notice that i need to top up about 300ml every morning and total i refilled is about 1.5L of water in 3 days time.
This indicates , with hindsight, the No 2 cylinder liner was already badly cracked ...... nothing to do with thermostat replacement or less than ideal air bleeding by your radiator pro.

So something is amiss and i send to hyundai service center to have it check. They told me it was due to bubbling when installing thermostat and it was solved by bleeding the radiator.
This Service advisor or manager from SC is nuts..... yes, he's nuts!

The next morning i open the radiator cap and start the engine to check again and to my horror the water bubbling and spilling like mini volcano thus i send to hyundai again. This time they help me do radiator bleeding again but after 1 hour still unsuccessful. During the testing, came out an error code saying misfiring in cylinder no.2 and the error was cleared. SA asked me to leave the car for them to have more time to check.
Few days later, they told me they need to open the engine head and check the head gasket condition, fearing burnt gasket due to overheating and i consented to it. Next day, i was horried that the engine lining at cylinder no.2 was cracked and that probably caused all the problem. I was also told that the engine head was bent to about 0.25° (i assume is degree since he didnt tell me the unit). I asked if he can try to claim warranty but he denied as my wife who drive this car only service based on mileage and forgot to follow the monthly interval schedule. She apparently skipped the service from nov 2015 all the way to nov 2016 LOL.
Naturally I was not satisfied as when i consented to opening the head i was prepared to pay for it as the 1year change interval probably damaged the gasket and stuff. What i cannot believe was that 1-year mis-sighted will damage the engine block lining as in the picture and i have to pay for the engine block defects..
Anyone can help or got suggestion for this scenario?
There are 2 parties in the wrong here, Few days later, they told me they need to open the engine head and check the head gasket condition, fearing burnt gasket due to overheating and i consented to it.

a) You: for not checking radiator water level regularly, which I could understand your 'over-confidence' from it's low mileage reading of 50k km.
b)SC who did servicing in 2017 prior to overheating: I suspect SC was negligent during servicing job.
They were:
i )NOT checking radiator/reserve tank water level AND not topping up water to level during servicing job, or
ii)SC did check radiator/reserve tank water level AND did top up water but ..... did it wrongly by ......
topping up water well above MAX level marking as indicated on the reserve tank.
OP, what's the interval in between the day you observed radiator temperature shoot-up and the day SC did servicing prior to incident ? ......
a few days to 1-2 week(s) apart , or after months ?
