Coolant

Hi,

When I fill the coolant to the correct level line, it goes a bit under it from time to time. What do you advise ? (see photo).

Nothing, keep driving it.

Yea, drive it, but I would pressure test it to find a leak. Hopefully it is not a slow seepage head gasket problem. Or are you saying it reads different when hot as opposed to cold?

Well, it is not clear to me. I always check it early in the morning when it is still cool ..

So, you are saying that after you have topped off to the reservoir line, for I assume when you find it lower than expected when you check each morning, that you drive it and then when you check the next morning it is either still at the full line or reading below it? Does that sum it up correctly? Any recent work on the rig? How long has this been going on? Ever see any drops on the ground? Plus, it sure would help if you put the rig info in your posts.

Or I could lick my finger and put it in the air and I guess what vehicle, depending on which way the wind is blowing.

Not each morning. It reads below after driving for many days ... no drops on the ground ..

Mine does the same. Every so often I top it off with premix dexcool
