Coolant Rust

[BayMonty]

Has anyone had any experience with Evans Waterless Coolant?

I had the major maintenance done a few weeks back but still seeing some rust deposits. Not bad, but would like to get it all out and replace coolant with Evans.

I run it in my 3.8 Mivec truck. Good so far, but my cooling system is setup for extreme temps

I had some bad coolant rust and I used evaporust and man, did it do wonders.... Got it at Walmart was like 20 bucks

Thermocure works miracles! I tried multiple products, flushes, parts on my 73 dart, this stuff cleared it out in one pass.

Same. My 2.5 Gen sat for a while before I bought it apparently as it would occasionally creep up the middle if I sat in traffic for a while. I opened the cap and it looked like OPs, mine took a few more passes, like 4 bottles of DI and a couple 100 miles to get it all out, but yeah that stuff is amazing. Plus its pretty environmental, too! And you can reuse it for several flushes if its still rusty; I used it in 3rd's, so for every 1/3 of the bottle to 1 DI.

Just make sure you don't need to to drive it right away long distances as releasing all those particulates may increase overheating short term. Mine jumped up past 3/4 of the way as I was putting it under load to get it to all come out on the freeway. But she would make it through the crazy snow in Utah and the avalanches in CO thereafter without ever going over.

You have to use the whole bottle and it is not reusable. It will works by dissolving and suspending the rust. Use the whole bottle with distilled water, drive the snot out the truck. Open the block drains and flush with distilled water until clean. Might require opening and closing the drains a couple times and 4 water flushes with distilled water.

If you look at the MSDS it's ~10-15% water (waterless! ha!) and the rest is ethylene glycol, potassium salts and sodium nitrate. Which is.. precisely what regular coolant like Prestone is. In my estimation Evans is a marketing company whose primary product is a convincing argument that their product is somehow different from Prestone, while it is in fact not at all different.

Thank you! Good info

I watched the manufacture's youtube video before buying it, it said specifically you could use multiple times for other anti-rusting purposes.

Besides, I got it to work with the way I described so I'm convinced it can be used in that manner from being that hideous color OP showed to a bright green.

I know it's been a while, but any update on this?

Hi BayMonty,
I ended up pulling the motor and swapping with a low mile one from an 89 I found. There was enough scoring on the crank journals that I wouldn't have wanted to keep running with it. After talking with the PO, I believe that the material in the coolant was all of the stop-leak that was put into the cooling system when the first head gasket issue came up. This material didn't really show up until I replaced the aftermarket aluminum radiator with the recently cleaned OEM radiator. I believe that the OEM radiator allowed a much higher flow rate of coolant and that stirred up the stop-leak in the block.
