Hi Tony, yeah it is been sometime since I've been here.... It was crazy times in last few years, getting better now. I had covid two times and been dignosed with acid reflux lately, now trying to find what I can eat😥and what foods causing my heartburn... Getting better now. Thank you for asking.
The fluid comes out quite fast, at the moment I just put a plug on the overflow pipe, in that way all liquid stays in the container. If not, then it takes about 15 min for overflow bottle to get empty.
I've replaced it with a new one with 108 kPa, but nothing changed. The next thing would be to try and changed thermostat.
I did not change coolant, usually I just top it up when it was getting low.
Overflow bottle filled to the "Full" line. When it is hot, it could be just a bit more over the line, but not by too much.
