Antifreeze

Yes you need antifreeze. Go to Caterpillar and get permanent Antifreeze and ask them how to install. Back in the Good Ol Days when they were building the Alaska pipeline I heard of truck drivers from Houston running to AK and having the radiator freeze while running down the road because they didn't use antifreeze.

Oh by the way if you don't buy the pre mixed dilute 50/50 with distilled water. NOT soft or tap. I'd be surprized if your cooling system is not ruined for running it that way. A rusted POS.

You need 50/50 anti-freeze and water in your radiator to protect against corrosion and boil over in hot weather. It should be obvious that you need it for any temperature below freezing.

I will second that.

Don't forget about your windshield washer fluid. If you're from the south it's only good to 32f. Use your fluid on the drive north. Once you get north buy some of the good stuff and mix it with that southern water stuff.

Yup, you need it, but what you are driving determines WHAT KIND of COOLANT you need.

It's not "anti-freeze". It's "antifreeze/coolant", and yes, you need it regardless of where you are driving, unless you like overheating your engine.

What they said.

Florida is flat. When the biggest hill you'll ever climb is about 6 feet high, overheating isn't much of a problem. When the coldest it'll ever get is in the high twenties, and then only for a few hours, freezing is no problem. There is no where else in North America where both those conditions apply.

Beyond that, every water-cooled engine I've ever heard of exposes a combination of aluminum, copper, brass, zinc, cast iron, and steel to the cooling system. Without the corrosion inhibiters of any of the anti-freezes, these metals are guaranteed to corrode like crazy. When that happens, it makes those engines very susceptible to overheating, especially, as well as sheer mechanical breakdown. If you've been running straight water for 35 years, I'm curious how many engines and/or radiators and/or water pumps you've had to replace?

EVERY water cooled engine manufacturer I've ever seen specifies a specific antifreeze(s) in their cooling system for good reasons. Just follow what's recommended in your owners manual. Some manufacturers allow less than 50/50 (water/antifreeze) mix for mild climates but most recommend a 50/50 mix for normal use changed at specific intervals unless they specify lifetime coolant. In my experience, "lifetime coolant" means how long your engine will reliably last if you don't change it regularly.
