I RUN MINE 50/50

 

thanks....
one mor thing is the radiator supposed to be filled to the top?

 

If you have an overflow resevoir, then YES.

 

Use distilled water 50/50 or even better 60/40 (antifreeze/water) that protects to lower and higher temps...if you have the plastic reservoir tank fill the rad full and then the tank to the top -full- mark, thats about 2/3 way up....marked on the right side if I recall, at least on the 05 KQ it is.
Distilled water is cheap, use it, not tap or well water they have too many disolved minerals.
