Which Do You Use?

[weberje]

Which antifreeze do you use in your ride?

-Prestone antifreeze or DexCool?


And what additives do you use for your radiator? I've heard good things about royal purple- purple Ice. Any takers?

50/50 mix Dexcool
Flushed once a year
126K on the clock had 0 when I bought it

DexCool can become VERY corrosive!!!!! Unless your dealing with warr. issues we ALWAYS get rid of that stuff!!!!

[irishpenguin13]

[irishpenguin13]

i'll have to post a pic for you sometime of my temp gauge. it seems extremely low.....but it works.

[irishpenguin13]

runs cooler than that. right exactly between the first and second mark.

[irishpenguin13]

Or Someone Could Have Put In A Cooler 'stat

[irishpenguin13]

not sure. im gonna hafta say no. last two owners were an old lady and an old man.

The only times I have seen DexCool issues is when there was a leak or somebody tried to run it for a billion miles. If your cooling system/cap is maintaining pressure and your flushing it and replacing it once a year....you'll never have an issue. And never mix DexCool with anything else.

dex all the way

I second that!!

If you don't put there stupid tabblets in;that shit eats aluminum like NO tomorrow!!! We have got some VERY high voltage readings out of some customers cars coolant before we changed it out. If your running "orange" try it. Take a multimeter and ground one probe and put the other in the coolant and see what you get.
But thats how they can tell real quick on a warr. issue weather or not it has recieved it required services. They do everything for a reason!

The first thing to get flushed and changed in anything I drive.
Including the 05 Goat with a $550 Mazier pump. http://www.jegs.com/webapp/wcs/store...53453_-1_10135
It keeps it cooler than the stock pump even in the heat out here!

Please elaborate. Faulty intake gaskets are not because of Dexcool, just poor design. If you notice, the most GM engines with that problem are the 3.1/3.4 V6s. And, if Dexcool is the problem, what about the Olds 307 V8 engines from the 80s? I have changed so many of those intake gaskets back in the day I am almost rich from that.
