Hello, I'm changing a part of the water leakage in my vehicle, I'm changing a part of the other part of the vehicle, especially the water recirculation pump-70 degree antifreeze I'm using antifreeze seals gives harm?
Water is what cools the engine. After 60/40 (antifreeze/water) you actually lose the cooling benefit and go the other way (decrease cooling efficiency). Antifreeze is not a good coolant - it's primary purposes is to raise the boiling point and lower the freezing point whilst providing a lubrication and anti corrosion benefit. The optimum ratio is 50-60% antifreeze and 40-50% water.
