whats a reccomend brand of coolant for rx7's? i noticed im at the half way point. so i wanted to top it off.

 

You can get Mazda OEM shit f you want..lol

Anything green is fine.. DO NOT get dexacool.. it will fuck it up..

DEXACOOL=THE ORANGE SHIT

 

I read that we should use ethylene glycol, not propylene glycol. The normal stuff you find is propylene glycol. Something about them being mixed not being good.

Of course, I just refilled mine with propylene glycol, regular stuff from Wal-mart.

That was from the 1st gen board on rx7club.com, so 2nd gen may be different?

 

i used to have to get dexacool for my grandam. i firgued that would not be a good choice for the rx7

 

No dexacool anything else is fine i run the discount auto parts shit in my car and have for years no problems ever.

at one time i was running purified water and water wetter. cooled just as good as the discount auto parts stuff i use now. i figured if there is no difference why change so i went back to coolant
