Yong Heng Flush of Water Jacket

Jump to latest Follow Reply
The Yong Heng does not have the fins as far as I know. Check out the vid at 13:45. Depending on the quality of water and additives one uses it may or may not need cleaned every now and then. I have never cleaned mine and it is doubtful many ever do. If they start running hot and you can't figure out why this may be the cause.

Sambo Cotton is one of the best with accurate no nonsense vids on these.

Yes, he had gunk in the water jacket I doubt there was allot of metal in there. I would expect it was mostly minerals from his water and or from whatever he used to treat the water so it would not corrode the metal. If you change out your water every few months this won't be a problem. I had an algae growth problem in my reservoir. I just changed the water every three months and it was not a problem. Then I added some water wetter and the algae growth vanished.

You should probly add something to your water so it is not so corrosive to the aluminum. Water wetter, watered down antifreeze or something like that.

Bio, No chemicals, as I plan to use fresh well water each time and throw water on garden, after use.

Brent, Per manufacturer's instructions, I flush coffee maker monthly with white vinegar, which has aluminum tubing. Why do you say you wouldn't? 

Gerry52, I've heard purified water is preferred since distilled lacks minerals and naturally wants to leech them from surrounding metals.

Anyone have any ideas regarding compressed air to dry water jacket, after use? Or maybe something to spray in jacket, after use, to displace water and protect metal?

Thanks for replies. WM

SDstephan,

Some might see this as a solution searching for a problem, but I think anytime water and metal come together, corrosion and eventual problems may occur. As I told the guy who found that abandoned F4 Crosman Nitro in a ravine, dealing with high pressure and corrosion on anything, needs to be taken seriously. Though being a member less than 6 months, I felt comfortable raising this question and seeking answers from those who may have already found solutions. Discussing it, and bouncing ideas off better minds than mine, helps me see more clearly towards the answer and may also get others thinking. 

My decision, since no corrosion exists in my new Yong Heng's water jacket now, is, after each use, to use very low pressure, compressed air to blow out, then spray a few pumps of Ballistol or WD-40 (silicone-based) in both ports. (Like couple of squirts of motor oil in spark plug hole on an engine heading for storage.)

So, Sir, as you can see, I've found a solution with help from a couple of knowledgeable members and that's one our forum's greatest strengths.

I can understand why you are so concerned now. Under those parameters my solution would be filtered/purified water as well. Although were it me I would add the water wetter as it can prevent corrosion for years, and keep the unit running cooler than plain water, with only the need to top it up every now and then. Still for as long as these things are gong to last, my guess would be two to four years for most of us, I don't see you having a problem cooling with just plain filtered water. I expect most are just using plain tap water in theirs.

Bio,

Was thinking along same lines. I use large under sink filter for drinking and cooking but, with replacement cartridges close to $40, don't think I'll use for Yong Heng. An inline filter, hooked to garden hose, would work, just need to find right one. Also, I'll need to research Water Wetter to see if it biodegrades safely. First I've heard that Water Wetter prevents corrosion, if so, might kill two birds with one stone.

Did you get M3 yet? Hope you got .25, as I'll depend on your "Impact" expertise for tuning tips. I agree that M3 is a bit much for a newbie, but something to grow into and enjoy for years, and with unlimited flexibility in modifications, what's not to love?

To those using straight tap water for Yong Heng Compressor cooling, please be aware that pitting and corrosion, on the aluminum water jacket, can occur. At time stamp 7:32 of Air Velocity Support's, 12/20/19, YouTube video, titled, "Yong Heng Compressor, 26 Month Update," the presenter shows actual corrosion from his machine. His solution, to address this on the replacement machine, is to blow out water jacket, with lung power, after each use.

A garage tank compressor, lightly pressurized, could replace lung power, to gently blow out system. A spray of Ballistol or WD-40 Silicone in each brass fitting (hose removed), should help to address problem. Leave hoses off brass fittings, till next use, to encourage airflow and further drying.
