Hi
It's a bit odd that water gushed out. If engine was still hot, you would've felt it but you mentioned "ice cold". Just keep an eye to be safe.
Ive opened a hot bottle before. Just a very loud hiss from pressure, but no water gushed out.
You never mentioned what was the culprit for the over heating, just a few things replaced.
There's a hack where you can view coolant temperature on dash. Check YouTube for it. Use it to keep a tab on temperature.
I would still do a pressure test overnight for peace of mind.
It's me bein dumb. Ice cold is me touching the water pipe which worried me, not sure why it was so cold but I idled it and used the OBC temp monitor u mentioned. No overheating, and that top pipe heated up nicely as normal. Checked bottom pipes as well, hit up to around 94 degrees then fan kicked in and dropped to 90.
Took it for a long drive then let it cool outside in the shade for a few hours, slight hiss but no more gushing water, I think either it may have been overfilled or not bled enough. Im going to bleed it again in the morning to see if any bubbles come out.
Reason for overheating was definitely water pump and thermostat. We tested thermostat and it was shut closed even after heating it up.
We were not happy with how fan was running so replaced that and it worked way better so it seems to be a combination of things.
I'm happy that cooling system is done now.
I guess sometimes people get paranoid when getting car back after a week, tend to check everything and worry 😂
For those who want to check coolant temp mentioned. I used the below:
