Checking Antifreeze in a 2001 Gallant

My GF went out and bought an antifreeze tester. It's the kind with the
short rubber hose. She says when she went to check it from the
overflow, the hose wasn't long enough. (The level was properly
between the fill marks.) She says she then removed the radiator
cap and couldn't get the hose in as there was some sort of grid
near the cap that wouldn't allow the hose to be inserted.
    Please comment on her description of things. Does it sound
correct?
   Then, if so, I would think the only way to get a reading would
be to put a longer hose on the tester, right?
   Looks like I will have to drive down and pay her a visit!
   Thanks for your comments and advice.

   P.S. I assume both overflow and radiator are theoretically
both the same in terms of getting accurate readings.

It sounds like the 'grid' you mention are the fins inside the radiator . There should be enough coolant in the radiator to completley cover the fins , which from what you describe doesnt sound like it does.

Might be a good idea to drain the radiator and refill with new antifreeze.

Is it Ok then to add antifreeze directly to the radiator full strength
until the fins are covered up to about an inch below the cap, or will
that affect the overflow adversely?
   Also to get an accurate reading on the meter, I would assume
you would then need to run the engine for awhile, to mix everything
properly, then cool the engine, then measure, is that right?
   Thanks so much for your help!

Hi Frank ,

It all depends how much antifreeze is already in the system , and the level of the coolant . If theres alrady enough coolant ( strengthwise ) and you add more , you could end up overprotecting it.

To be 100% sure , its easier to drain it off and refill with the correct quantity .

If you decide to just top it up , then yes run the engine and let it mix in before taking your reading,

I agree with some others about the level improperly being below the
fins.  Here is some extra advice:

The level should always be overfull when you remove the main radiator
cap.  The radiator is a closed system, and uses vacuum to suck fluid
from the overflow back into the radiator when the engine cools off.  If
the system can not hold a vacuum due to a leaky hose or radiator cap,
then the coolant goes out to the overflow, but never comes back.

On our 99 Galant, I noticed corrosion around the radiator hoses at the
engine.  The factory spring clamps are insufficient to maintain a
perfect seal.  I moved the stock clamps a bit (no need to remove
completely) and added worm clamps and my problem with lost coolant was
cured.

When you flush your system and add new coolant per the coolant
manufacturer's recommendations, be sure to use distilled water.
