My Maxima is killing any antifreeze I put in there, granted it's hot here in South Florida, I go though a whole bottle at least once every two weeks. My car has 170+ miles on it and it's a 95, I got it at 118+.

I only tune it up and change the brakes/rotors is it time for a raidiator flush?

 

what do you mean by "killing any antifreeze." -it gets low and you have to keep adding? If so, you've got a leak in the cooling system and flushing the radiator won't solve that problem. find the leak, repair, and you could flush the radiator at that time, never hurts.

 

Where is your antifreeze going? The cooling system is a closed loop system. If you are having to keep adding antifreeze then you are losing it somewhere. A flush will not hurt anything but you have a leak(s) somewhere if you're having to continually keep adding fluid that need to be found and fixed. And when you're adding antifreeze it should be diluted 50/50 with distilled water for maximum effectiveness or buy the pre-mixed varities.

 

its either going into the engine(BAAAAAD) or into the street (not so bad but still bad )

dont do any flushes untill u get that original problem sorted out

 

Do you smell antifreeze after driving for a while? You might have a pinhole leak somewhere or even a bad radiator cap (if you're lucky).

 

Mystery solved see his other post. Unfortunately he has a milk shake maker. Bummer deal.
