she only took 4L this time, last time i thought i put 4L fluid 4 l water? am i wrong? i put stop leak in her this time, could that have pluged it up? any way to tell?

Mine takes 1 gallon Antifreeze and about 1/2
Gallon water and it's full, that's about 4L and 2L
for a total of 6L fluid, I'd say she's full

is it bad to run pure fluid? cann it do damage?

Pure Coolant doesn't cool as well
as a 60/40 mix, but I don't think it
can cause any damage.

It's a lot easier to use the premixed stuff.  I buy the Green premixed stuff from my local O'Reillys.

Straight water or pure antifreeze is never a good idea except in an emergency.  Always mix according to the instructions on the container if you are buying straight antifreeze.

Straight antifreeze will actually cause leaks where you never had them. Most likely place is the water pump seal.

WOW!!! i better go out rite now and fix that. last thing i need is more leaks. thanx sooooo much
