I jumped the gun and forgot to put the question in my hurray to get going. Sorry about that. I have two questions about the additive for the rad. The first one is how much Watter Wetter do I add to my '04 700? I live in an area that has a cold winter and I need to keep a strong mix of antifreeze. The second question is, do i need to put it in at this time of year? I do not think that radiator heating will be a problem for the next four or five months. Does it hurt to leave the additive in all year round in this climate?Thanks

 

If I remember it's 1 ounce per quart, so 2-2.5 ounce's will be enough.....

 

don't run water wetter in the winter!!! it will freeze

 

Thank you for the heads-up, this will be a spring job to add the water wetter.

 

you can run water wetter in the winter. test you coolant strenght and if its good to where you are then your fine.
