Ok so my D is loosing coolant at a rate of 5 quarts a week.
But where is it leaking?
Not a drip under it.
Not a stain anywhere.
Doesent smell inside.
All plugs looks the same.
So were is the hidden leak?

Time to get a coolant system pressure tester and hook it up.

I agree with Mark. It could just be a loose hose clamp that only leaks while the system is under pressure. I've seen it happen.

There isnt any stains around the clamps, im mostly
worried about the small hose from the pump to the intake
witch is mounted under the alternator and ac compressor.
Its completely impossible to see it.
I have a faint coolant smell from the engine when hot..
