Rust question
Does anyone know if engines run with antifreeze have less internal rust than engines cooled with just water? Thanks in advance, Craig.

Re: Rust question
I think all anti-freeze has some kind of rust/corrosion inhibitor, look at the lables. The thing I notice about it is that it is slippery and will leak where water might not, and I need to tighten the hose clamps a bit tighter.

Re: Rust question
Here's what Mr. Google says:
The modern antifreeze, however, does much more. It provides year-round protection of the cooling system: With proper additives it prevents freeze up in winter and boil over in summer (especially in cars with air conditioning). It provides protection from rust and corrosion and does not harm rubber hoses and plastics. |

Re: Rust question
Thanks again for your replies. I posted this because it occurred to me we have a better chance of getting thicker cylinder walls in a block that has had antifreeze run in it. I doubt anyone changes to water in the summer. Also if anyone doesn't live where they need it they might want run run it anyway. Comments welcome, Craig.

Re: Rust question
Water cools better, but you still need rust protection, and of coarse theres winter...so I use 50/50 antifreeze

antifreeze should be changed after 2-3 years. In the old days they lasted longer , but not anymore. |

Re: Rust question
So totally true. My 36 totally sludged and rusted up dictating a tear down. My old time radiator shop said it was a result of Prestone anti freeze. He said to only use Shell antifreeze.

Re: Rust question
I have a block that always had good antifreeze, cleanest block I have ever seen ,no cracks,not even any”factory” ones.
And blocks that are rusty inside,no corrosion protection in coolant |
