Coolant issues

Yes, water works better than antifreeze at exchanging heat.

The higher the antifreeze percentage the worse it will be in warm weather.

So I shouldn't worry too much on that slight difference.

Like the engine runs perfect, no engine light and I only need to do a 3500km trip to a colder region.

Well, you should use the proper coolant.
But, no I wouldn't really worry about it being where it is.

Try rebleeding it but squeezing all the kinks and bends in the radiator hoses with the car inclinded so the open cap is the highest point.

I wouldn't worry too much since you changed out the sending unit.

Honestly, you should just drain like 20% of it out and fill with water and then refill with antifreeze when you get to a colder climate.

I'm sure it's fine, but if I was about to go on a 2,000 mile drive I'd make sure my cooling system wasn't fucking up.

That would just dilute the capabilities of the coolant.

I might do that since I am not particularly happy of doing a trip like that with "overheating"

Water is the coolant. The antifreeze doesn't cool.

A car with 100% antifreeze would overheat as if there was nothing in the radiator at all.

I don't know what mixed you used, but it shouldn't really overheat even with 50/50 mix. Could just be your gauge or something like the sending unit not calibrated to the gauge, idk. But 50/50 shouldn't over heat even if it's like 20c outside.

It'll actually be better on fuel ever so slightly

Thanks for the help guys.

It may be an issue with your thermostat not opening properly
