Which antifreeze/coolant do you use?
There are many to choose from, so which one do you use and why?
With this poll keep in mind that many of the brands have several different lines. For instance like GM, some brands have both Dexcool lines which are Organic Acid Technology (OAT) based, and standard ethylene glycol lines. Since it is pretty much accepted that OAT based (Dexcool) antifreeze is not good/recommended for the LT5, all the brands will be assumed to be ethylene glycol based unless specified otherwise. Also keep in mind that not all glycol lines have sufficient silicates or are not in fact "1825-M" compliant, which is recommended. As always, if the brand you use is not listed, post it and I will amend the poll to include it.

Re: Which antifreeze/coolant do you use?
 I am not using this yet but am thinking of using this  Actually I have not found ZEREX original formula yet  This Poll will be as exciting as the oil Poll I am sure. Last edited by Dynomite; 02-02-2010 at 12:38 PM. |

Re: Which antifreeze/coolant do you use?
^^^ According to this chart it looks like it is one of two in the Zerex line that meet GM 1825 spec.

Re: Which antifreeze/coolant do you use?
I'll go take a pict later, but I get mine from the chevy dealer. It's p/n 12378560.
It's expensive for sure, but it's what came in the car from BG back in 90.  I may go to the local NAPA store and see what they have on the shelf or what they can order that is an E-glycol silicate coolant 1825M spec. I have only one gallon of my GM stuff left after this yr's flush & refill.

Hammer suggested this in the Leaky Radiator thread  http://www.zr1.net/forum/showthread.php?t=10241&page=2  Re: Leaky Radiator Another item that can blow radiators is if the thermostat wasn't installed correctly in the housing. Easy to check, but have the catch pan ready if you pull the thermostat (don't ask me how I know that). Make sure it's seated correctly. Hold it in flush with the housing, use the bracket (Marc's trick) or a putty knife while you tighten the lower housing bolt. Last edited by Dynomite; 12-12-2010 at 01:06 AM. |

Re: Which antifreeze/coolant do you use?
About a month ago I read a number of antifreeze threads and freaked out! Last year I had installed all new hoses, clamps, new 180 (& drilled out, as explained on ZR-1 FAQ) stat, & flushed the system. I then used distilled water, water wetter and 10% Prestone. So big mistake using Prestone (as I had read), it has taken a month but I will be receiving my GM antifreeze tomorrow via GM Direct. Then I will re-flush the system and make it 10% with the GM green stuff...I don't drive it in freezing weather & it stays in a heated garage.
So I think I have it right, finally...

Re: Which antifreeze/coolant do you use?
Per recommendation of someone here I went with Napa that meets the specs.
