    Default Coolant Hose Issue?

    We have a Haas VF2 with some very odd debris clogging the coolant strainer and nozzles. A guy opened up the strainer and pulled this funky green debris out. To me it looks like the inside of a hose, but since I haven't taken anything apart I'm just guessing. Has anybody else seen anything like this?

    It looks to big to go past the pump ,, so it would have came from between the pump and strainer ?

    That year is the machine ?

    Weird. Have you cleaned the coolant pan, anything to see there?

    It looks like a Mountain Dew bottle got sucked through the pump.

    That is how you tell what resin it's made from.

    Doesn't look chewed up enough to have gone through the pump. My guess is the coolant hose doesn't like your coolant.

    Is it sort of gummy/rubbery, breaks in bending, not very strong in tension? The Mountain Dew comment may not be far off. I am dead serious here.. You should see what becomes of a gallon of Coke-Cola syrup once dry.

    It's a long explanation of how I know this but if you take a liter of soda,mix with two liters of clean water add a dime size dollop of dish soap. Stir well and allow to sit you will get in a few days a layer of a brown rubbery material on top. This material is corn syrup with the water separated out. I imagine it would be green with Mt Dew.

    The components of coolant could very well act as soap and my suspicion is somebody accidentally or intentionally dumped soda into the coolant.

    Just a theory but it is based on fact and experience. If you ever worked in a place with a soda fountain, you know this material.

    I'm inclined to agree w/ DavidScott's assessment - It looks like the internal liner of a hose which has failed and separated ?? It's an interesting post for sure. Tell us if you figure it out.

    Coolant sump was just sucked dry and cleaned. Nothing unusual in there.

    Fortunately we have the kind of shop where people don't do that type of stuff. My guess is the flexible coolant hoses aren't compatible with Cimcool Cimtech 320.

    I think your problem is Cimcool. Worst shit I ever tried. After about 3 months it would start to gel up and clog all the screens. Inside of the machine would be covered in green slime.

    Ditch the Cimcool, ditch the problem

    That's interesting. Our Cimcool doesn't have that issue. It's actually the best, most trouble-free coolant I've ever used.

    you might call Bob taylor at Application specialties inc in kent ... I changed to Qualichem 250C collant a few years ago and its hands down the best stuff I have ever found .... FYI .. Ask for a free bucket to get started with ,,,

    Clean out the old stuff as good as you can then flush new stuff for a hour or so at 2% mix then clean once more and fill at 7% .....
