Looking for modern antifreeze recommendations

I’m looking for recommendations regarding modern long-life antifreeze.

Now that I’ve installed my new 460 engine, had the radiator professionally serviced and am installing a brand new heater core, since I have yet to add coolant it seems as if it might be an ideal time to switch to a modern antifreeze that doesn’t need to be changed so often. Does anyone have any recommendations?

  • There may still be issues with original "long life" and some of the parts in a design that old
    That's why I switched everything over to a quality "universal" antifreeze.
  • I use nothing but standard ethylene glycol and distilled water in my 95 F53 460. Change it ever 3 years. When I pull the block drain plugs, there is no muck in the block. Water pump lasted 90,000 miles.
    It probably makes no difference what you use as long as you do the proper maintenance.
    I'm sure the diesel guys will tell you all their needs but your ol 460 is a lot more forgiving.

    I'm curious, what problems exist by using the long life coolants.

  • I don't know if they have changed things with regard to antifreeze but I wouldn't run a motor on straight water myself.

  • If your system is thoroughly cleaned out, almost any of the name brand anti-freeze products will last close to 5 years. I would add a can of water pump lubricant to the antifreeze mix just for a little added protection. You can also use distilled water which helps a little bit, especially if your local water is high in minerals.
