Default No problem but question about the radiator and coolant level.

When my car is cold I won't be able to see coolant down the radiator and the overflow is at the hot line. Doesn't matter how many times I top it off won't stay there. Is this normal ? Do I need to siphon any out of the overflow?(not going through the hassle of removing the hole thing) runs great, no leaks and now with the tune won't go past 170 at most. Not past 200 prior to the tune.

If your radiator is not full, no matter how many times you top it off.....you're losing coolant.

I've debated a blown head gasket. Done everything but a compression test on the cylinders. If I do it's a small *** blow. Run it till it breaks right ? I've pressure tested the cooling system, holds. Checked plugs. None of them were clean and one was gunked up. No white smoke. Hate to even think of
It now that I have it running so good.

Could be that you have a leak in the hose from the radiator to the remote reservoir. Quite common. A system pressure test will not detect it.
