Over heating???

Agreed, but it's not the norm in this situation of what usually causes that problem.

I guess for starters the over flow hose should of been routed to a cleaner environment. It's located in the dirtiest place possible.

For some reason the secondary clutch is dirtier then the primary and the brake being there also probably adds to the filth. Something the R&D probably over looked or never addressed.

I have noticed the hose can actually get condensation in it, water droplets not coolant.

A one way check valve could help stop the contamination but I don't think it would keep it from happening in an extremely dirty area.

It's like that old saying water does run up hill and this is in a very turbulent area.
The foam is a give away of how dirty it is, below the clutch shroud it's black with grime.

Side note also, the top where you grab it to open the panels was overlooked, foam gets damaged right away, these were damaged upon pickup. I'm sure I added because I'm not gonna treat it like a baby.
I keep my **** clean but there's a line at some time

Anyway,
It's a very turbulent area and the condensation of the bottle would draw I believe.

When it's running at operating temp watch the circulation in the bottle, it's pumping and hits the other side of the bottle.

Something that just dawned on me after thinking about the last pics , that coolant shouldn't be ORANGE like extended life coolant !!!!!! Mine is good old green ethylene glycol just went out and checked , didn't know the O.E. ' s switched to that ????????Hope they haven't , that's what block test fluid looks like when their are hydrocarbons in the cooling system !!

Hawkster I don't think their is anyway for that much dirt to migrate up that tube !! It isn't like a coolant recovery system on a car which will sometimes pull coolant up the hose from the overflow bottle ? That hose is either under pressure when venting or same as atmosphere when not . My overflow hose is spotless all the way down and my coolant is GREEN not orange somethings goofy here ??!!
