Jeff, you might check with Tracy Crook.  Way back when, he attempted to use
some clear plastic/nylon cored reinforced hose for his coolant system for
the same reason (I think) - so you could see what was going on.  As best I
recall, it was not up to the task due to heat and pressure - but these were
the main line hoses and not just to the header tank.  

 
I can not recall the type - but think he got them at the local hardware
store.

Thanks Kelly, I copied (Bill Eslick's) installation (seen at Round-up) and
the see-through aspect of that hose was a major selling point; it's easy to
see whether there's air or fluid in the line, which is very helpful .
ideally there should be fluid in the line and about 1 cup in the expansion
tank; I suppose removing the cap would provide same information . but the
tank has to be de-pressurized, cap removed and re-pressurized before flight.

Bill any comments on durability of that hose?

   Jeff,

    You might keep an eye on the plastic hose goinng to the bottom of your

expansion tank..........This particular hose is not durable and under the
high

heat under the cowl (perhaps not during your Canadian winter) might have

a short service life..........Project looks great and am looking forward to
all

further flight test info..........

-------------- Original message from Jeff Whaley <jwhaley@datacast.com>:

Thanks to you all for the congratulatory comments . attached is a picture of
expansion tank and preflight roll-out . the orange line is fuel return; the
brass is pressure gauge pickup and snifter valve installation.

After reading Eds' email I now know why the water temperature was so high.
I installed a thermostat with the onset of cold weather, but I couldn't use
the original Mazda thermostat because my temperature bulb protrudes across
the bypass hole.  Originally the bypass hole was plugged and there was no
thermostat; however, I removed the bypass plug and used a non-Mazda
thermostat !! . so that's why the underside of the Mazda thermostat is so
long! Thanks Ed for setting me straight and based on your comment about 20%
loss of efficiency, I could possibly see 230F x 0.8 or as low as 184F on
next flight . that would be great! For now the thermostat is gone and bypass
is re-plugged.

Closer examination of the belt and rubber deposits on underside of top
cowling suggests the belt got jammed in the pulley and cut by friction.

I tried again last night to remove the alternator pulley nut . what's the
secret? Left-hand thread? Loctite or what? It's so tight I'm afraid of
damaging something trying to get it off.

Jeff
