Overflow rad tank level

[coopns]

My overflow container level is right on min when van is cold. After warm up and drive around for a bit, the level doesn't get much above min. Should I add a bit more fluid or is she ok?

Yes, add in enough to get it to the max "Cold" (or max level if there is no cold indication) level. You don't want to give it the chance to bring in air pockets to the system.

It won't hurt to add up to the MAX line when cold.

Even if you add too much, the extra will overflow out of the system when the system is hot.
