Changing Nexon's coolant at home as a DIY.
It has been 3 years already with the Nexon ,and I was noticing deposits in the coolant degassing bottle. I wanted to do it myself at home,so I purchased 4 litres of coolant and went about changing it with the help of my son.



Disconnected the battery first

I collected all the coolant in a container to measure how much came out

Despite collecting it some of it spilled on the ground

This funnel came in very handy

I idled the car for 15 minutes.Coolant level went down.I filled up again.I repeated the procedure 4 times. I opened the AC vents to full heat during all this.
Hope it helps other Nexon owners!
I enjoyed the DIY very much. Thanks for watching and reading!!

Hello Doc, did you not flush the radiator? It is always advised to flush the coolant when you find some debris. You can use Distilled water and vinegar to flush the coolant. I think if you fill directly in the radiator, you wouldn't have had to fill the reservoir 4 times(Correct me if I am wrong).

Most of the cars don't have direct access to radiator nowadays and no radiator caps. I think that's the case with Nexon also.

No I didn't flush the radiator. I removed the exit valve and radiator was drained through that only. Car is not old and coolant was not that dirty so I didn't flush it. I repeated the procedure 4 times to get rid of the air trapped. Bubbles keep coming out and to fill back completely press the hoses of radiator repeatedly after its becoming hot,to remove the trapped air. It takes quite long to remove the trapped air fully.

Correct. I will have to put water in the plastic bottle to do the flush and it will never come out fully. It will mix with the coolant.

Oh ok. I too haven't seen radiator cap in my Tiago. Thought I should I should remove somethings to get access and didn't bother to look at it.

I know this method and tried in my duke 390. Coolant didn't drain completely. Had to open the radiator cap. I thought cars also have same procedure and didn't know that cars don't have access to radiator now a days. Thanks for clarifying.

Cars do have the same procedure,but it's nowhere written in my manual about flushing coolant.It's only changing. Flushing can be done,but it's a tricky and lengthy procedure.
Moreover it was not required. My erstwhile Swift vxi and Ritz vxi had a separate radiator caps,and there flushing was easy.

Hello Sir @mayankdixit
Facing a strange problem. Front and rear side parking light automatically shut off after some time. But again it works fine after switching on off. Kindly tell me how can I fix it. One more thing, kindly share a closer shot of drainage point, from where u have drained out the old coolant.
Regards

I have put no.to your queries for better answer:
1) Your BCM is acting up.You may have to visit TASS for it.They will reflash it/maybe update it,if it's an older version.
2) Old coolant drainage is near the lower left side of radiator.I will try to take a picture if possible.Its visible by a small black pipe coming out of radiator bottom.
