Sumo Posted April 18, 2003 Share Posted April 18, 2003 Which coolant do you use in your Z's Standard Green anti-freeze or the "Kool Aid" extended life used on the newer cars. Quote Link to comment Share on other sites More sharing options...
Guest silverbullet Posted April 20, 2003 Share Posted April 20, 2003 I once used the Prestone extended life A/F when it first came out some years ago in my mothers 1990 Nissan sentra, flushed it real good with chemicals like I do every year everything was very clean we (I) decided to install the 2-year extended life stuff, 2 yrs. later I went to flush it and flush and flush long story short that stuff so rusted the inside of the block I simply could not get all the rust out and every year after that I still get a significant amount of rust, absolutely will not use it again!

Guest rick458 Posted July 28, 2003 Share Posted July 28, 2003 you have to be careful with different antifreeze formulations they are made for specific component materials ie aluminum Vs copper or brass or cast iron that is why new owners manuals tell you what to use and what NOT to use my 2002 Explorer show specifically to NOT use the red Quote Link to comment Share on other sites More sharing options...
fl327 Posted July 28, 2003 Share Posted July 28, 2003 i use whatever is on sale for 5.00 or less, have a very mild climate, doesnt ever get to freezing around here, so i use a 25/75 coolant ratio to water, and for some reason or another, i end up flushing out the coolant about three times a year, so far, no crud! also found car runs better with the least amount of antifreeze possible, i only use it to avoid corrosion and scale.

Guest ON3GO Posted July 28, 2003 Share Posted July 28, 2003 i alwasy do like 70% water and 30% coolent. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted July 28, 2003 Share Posted July 28, 2003 Antifreeze not only prevents corrosion of engine parts (in particular aluminum parts), but it lubricates the water pump. Not sure what the advantage of running other than a 50-50 mix would be. Besides, never can tell when you might make a road trip into the mountains. I have also read ariticles claiming Toyota's antifreeze is incompatible with standard antifreeze. Thus when switching types make sure to flush the system to completely remove any traces of the old antifreeze. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted July 28, 2003 Share Posted July 28, 2003 30/70 with green stuff. And two water wetter added for summer time. Quote Link to comment Share on other sites More sharing options...
Guest cbrunberg Posted July 28, 2003 Share Posted July 28, 2003 I'm planning on trying the Evans waterless coolant. It's supposed to wet the surface area better, lasts a lifetime, uses a 0 - 3 pound cap (hoses and rad. last longer), doesn't need a thermostat, and is environmentally friendly. They say it's regularly used in heavy equipment , race cars and there new formula is great for daily drivers. It costs 25.00 gal but it's a lifetime product 8) . Read their website. http://www.evanscooling.com/main21.htm Carl Quote Link to comment Share on other sites More sharing options...
