I have been using engine ice in both my Vulcans and when I drained it so I could put new o rings on my coolant pipe going into the head the color was the same as it went in four years ago my bikes run normally cool and never had any issues with either bike it’s premixed and a half gallon is what I used in both bikes. Cost about 35.00 half gallon.
I used some Water Wetter once. Owner of a motorhome with a 440 Mopar was obsessed with getting the temperature down from the normal operating temps.

We used that and some other mods and got it down to 160 degrees. I wouldn't run mine like that, but that's what he wanted.

Find a way to get rid of the deathcool, I kept a gallon around and it ended up in a vehicle.

I researched quite a bit but don't recall the reactions and chemistry involved. I just know it's not for cooling systems. It might make good ballast for tractor tires, but there are cheaper liquids.

My last three vehicles purchased came with Dexcool and mud. I do recall picking the last vehicle up and the seller put green antifreeze in it before I left. There's a theory that mixing it causes the mud, but I think it occurs anyway.. Another theory blames exposure to air, but there's always air in the overflow bottles.

This truck has been the worst I've seen, so much mud in two flushes. It couldn't have lasted much longer, but looks like new now.
Time to change the Coolant in the Vulcan since its over 20 years old. I started it up here and there let it run for 30 mins but it didn't overheat. Im just going to change the coolant because it has little particles in reservoir. I just want to know to myself that Im safe, that will cause one less of an issue for the cooling system. Some say use Dexcool but I use Prestone in all my vehicles except the audi. Its picky. Anyone have an idea on what to use on our 89' Vulcan 750? Thanks!
