Radiator questions

[ZeaZer]

I went to check out my m10 radiator fluid since i just replaced the radiator and the fluid isnt filled to the top like its visible but kind of hard to say how deep it is maybe like 65% full is it like that because i have absolutely no leaks and i just topped it off with new antifreeze/water mix

If you only refilled the coolant when you replaced the radiator and didn't check it after the car got up to temp thats why it's low. When the car get up to temp the thermostat opens up and lets more water into the engine. So you need to top it off again

Im going to leave it for now check it again in like a week

Being that the m10 doesn't have an overflow tank, the coolant level should be about an inch below the neck when cold. When it heats up any excess will push itself out and there's your level

Ok my car was up to temperature and it looked like 40% full again no leaks what's so ever

Anyone know what's happening?

Yes. You're posting a nebulous question.

But if you're losing water and it's not going onto the ground, the next place
to look is the tailpipe. A sniffer can detect antifreeze in the exhaust....
