mini buildup

[broncomatt]

I have used everything under the sun for overheating issues. THe water wetter works, but not ideal if your in an area that can freeze. I'm using the edelbrock high flow pump and it does work good. THe fan shroud is the biggest help you can do. The fan type is also very importent, as little flex in the blades as possible. I also recomend an aluminum radiator, I have a Howe. If still persistant, try a lower temp t-stat. I run a 160 in mine, just to have some heat. Other wise I wouldnt even run one. The other thing I have seen is a bad coolent mixture. NIssans are prone to not gettting up too temp if the mixture is too much coolent. We mix ours at 40coolent/60 water. Just becarefull if you let it sit where it can freeze. Tell me what your running now and I may have more suggestions.
Love the new engine!
