OK,,, well I'm a little dizzy from quickly speed reading all the above( and a few brews!) so I'll just go with any of the above & change every 2yrs., never get to 24,000miles. Way too much thinking about this(also the engine oil fiasco). Put in an alum rad. last year, so I gotta kinda watch out. Here we go to extend the thread!!!

Back in the 60s and 70s I was a Chrysler Plymouth mechanic,Ma Mopar told us there was a reaction to the solder used in the rad with anti freeze used,caused the corrosion problems.

OAT type antifreeze is especially hard on solder. The glycerine is supposed to be much kinder to it, but more expensive to produce.
Ethylene glycol (an IAT type) not so much.

Ok, let me see if I pasted this correctly:

HOAT formulated antifreeze brands to avoid
HOAT or Hybrid Organic Acid Technology
Propylene glycol based good for 3-5 years, color = orange or yellow (less poisonous than IAT)
color = yellow or, possibly, green, pink, blue, red or orange

OAT type antifreeze products to avoid
OAT or Organic Acid Technology
Anything labeled “extended life” or “extended service”, Dex-Cool (GM brand), Zerex G-05, Zerex Asian Vehicle, Most Prestone products

IAT type antifreeze products to seek out
IAT or Inorganic Acid Technology
Ethylene glycol based, lasts for 3 years or
36K miles, color = green
Peak, Peak HD Sierra, Zerex Original

Ed, it looks good. 2/24000 for me,LOL. Read too many stories about dex-cool,not for me. Course, GM never could get anything right,and I part-timed at a GM dealership for 3-4 yrs!

Heck, I probably butchered the copy/paste.
In any event, good old green for me....and NOT Prestone.

Peak for me. They are an NHRA sponsor of John Force and company. Also, the local NAPA carries it and I like to support the old guys that work there...

What's really scary is that those old guys where there 40 years ago and were very young at that time like myself, but I don't look old, how can that be? Now I have to see what I've been using since 1977, it's green and smells sweet.
