you dont have to use any antifreeze in an engine if you live in warm climates. you can run water but corrosion will set in. Use Water Wetter with the water. It has anti corrisive agents of that of antifreeze in it. Water has superior heat tranfer of any other glycol based coolants.
Why do racecars use it?
1. water is free
2. it evaporates
3. easy to clean up
4. better heat transfer than antifreeze
5. lower engine temperature, you can run more timing
I wouldnt use straight water without a corrosion inhibitor like Water Wetter.
All water pumps that i have put it are sealed bearings. How do you lube a water pump?
