I would like to know what people are using in their cars for coolant/antifreeze. From the factory, our cars came with the green inorganic compound fluid. That was pretty much the industry standard in the 1960's and 1970's. Since that time there have been new fluids introduced in the marketplace. The organic compound fluids, OAT, and the hybrid version or HOAT. GM has their own specification, Dex-Cool, and several of the aftermarket companies sell a "universal" coolant. These are all various colors from yellow to pink to orange to blue, etc. They all have different characteristics, positives and negatives for the collector car. I was wondering if there was a consensus as to which is best for our older Mustangs.

i use the green zerex.

Started using Evans waterless coolant, won't corrode internals. Good for cars that are seldom driven or even driven cars. Costs a bit up front, but does not have to be changed out like regular coolants.

Hi Charles,
I've been considering using Evans too. Did you start from a dry block or did you convert from a prior glycol based anti-freeze system in the car? I'd love to her your thoughts about using it.

Started with a clean system, no prior coolant. There's lots of good info on the web with tips on cleaning out used systems.

Great info....just watched a Jay Leno video about it. Never knew about it but wished I did when my car was restored. Will need to do more research but thinking it could be tough to eliminate all but 3% of the water from a system using water/antifreeze.

Only difficult area might be the heater core. Pull the block plugs or knock a freeze plug out if you have to. Let it air dry with the hoses all pulled a few days.

OK, guys...then just do it the "concours way"...pull your engine or rotate the car! ;D

I would like to know what people are using ....
In the winter I use Low Tox by Prestone or Zerex I think. Most the auto parts stores carry it or will order it. It is exactly as effective as regular antifreeze, but it is not sweet tasting and therefore your pets won't drink it and DIE like they will with regulat antifreeze.
In the summer I use water with water wetter added.

Thanks for the input.

Thanks for all the info. I'll have to check into the Evans. Then try to evacuate a few cooling systems. BTW, I always flush Dex-cool from any GM vehicle that has it. Replace with global. Dex-cool sucks.
