Great forum members -

We have:
WDE46 = Automotive Engineer
SeanC = Ph.D Theoretical Physics

Now if we can find a Materials Engineer to chime in... we'll be rockin'.

Actually our upper and lower rad. hoses are quite soft when brand new.

Also, "tapping" into our cooling system at the bleeder screw (and at the auxiliary sensor) locations wouldn't be a bad idea without too much concerns of weakening or causing a part to fail.
