Proper level ( volume ) isn't the issue, having the coolant corrosion inhibitors at the proper % is the issue. Even then, coolant can slowly weep through gaskets then corrode bolts because the weeping coolant is trapped , loses corrosion inhibitors and does not get "renewed".
Be aware that coolant passages on the intake manifold and cylinder head may be pitted resulting in more work than anticipated.
