Should I Use Water or Antifreeze Coolant?

[V4F]

I use 50-50 + water wetter . I flush my system spring & fall .

[mcorrell]

I use 50/50 water/Sierra antifreeze which should be a little safer around pets and kids on "open" systems. We get wild temperature swings in the NC mountains which allows for sub 20 degree mornings and 50 plus afternoons, so the "old" cars are never really put away for winter like they were when I lived up north.

Tom, I am a glutten for punishment, but I leave vinegar for at least 6 weeks. seems to take the rust out of everything.

never found 4 weeks to be enough....................

Antifreeze will leaks sooner than water, water cools better but boils at lower temp,i use rust inhibitor and water.

I've seen quite a few that use Rust Inhibitor and water that have some pretty nasty looking water in them. I think I'll stick with my 50/50 Peak and change it every two years.

This is one of those discussions that either side is set in their beliefs and I know I should just stay out of it. There is no way to convince the other side you're right... Haha. Like oil, air filters, etc.

I used water and rust inhibitor in my new rebuilt engine for three head nut torque checks, then 50/50 prestone and water. And I use Rotella 15/40 a full flow oil filter, K&N air filter and use Marvel mystery oil on occasion.

I run 50/50 Sierra and water in mine year round. I leave a 180° thermostat in it also.

I've been reading up on Evans waterless .

In both the 5-cylinder Mercedes diesel and 4-cylinder Model A Ford we use 50/50 PEAK brand coolant. Seems to work better than water with much less rust and radiator grunge.

"I've been reading up on Evans waterless"

thread on this about a year ago. You may want to check it out. The Evans does not boil until 320°, but your motor will be a toasted mess by then........

Another hoax

Where did you get this information from. Please name your source. Wayne

I run it in my S/W Town Sedan. No complaints. It never gets near 320 degrees in my car, so the engine is not harmed from using it. It will not fix a cooling problem (bad radiator, etc.). In fact, it has less thermal capacity than pure water, it is closer to 50-50 EG antifreeze. So cooling system needs to be good already.

After a long hard run at 55 MPH in the hot Texas summer, and then stopping at a red light, you can watch the coolant temperature really climb and nothing boils out. As soon as you start moving again, the temp drops back to 160-180 and all is good.

YMMV.
